DF115ATX - Black, Electric, 25" Shaft Length, Remote Power Tilt and Trim.
If an engine with performance is an essential part of your boating life, then you need our combination of quality, reliability and choice. The Suzuki DF115A is perfect for all kinds of freshwater boats, inshore boats and even offshore fishing boats. Bottom line, you won't find more power, more advanced technology or a more compact package anywhere.
“The Ultimate 4-Stroke Outboard”. Since its introduction, Suzuki's flagship 300 hp V6 has been a showcase for advanced technologies and designs. The award winning DF300AP incorporates "Suzuki Selective Rotation" - the world's first outboard that combines standard and counter-rotation operation into the same lower unit. Two-Way low water pick up inlet provides engine cooling with increased water flow. The DF300AP also features “Suzuki Precision Control”. This fly-by wire control offers silky smooth shifting and throttle response. The addition of "Suzuki Lean Burn Control" with "Oxygen Sensor" can provide an improvement in fuel efficiency, especially while cruising on the long run home. Go with a Proven Winner, Go Suzuki.
Packed full of innovative engineering, this super quiet and reliable outboard means that whether you’re boating for work or play, you never have to worry.
Suzuki's DF150AP incorporates the Drive by Wire Suzuki Precision Control System for easy, smooth and precise throttle and shift operation. The AP model also incorporates Suzuki Selective Rotation which enables the outboard to operate in either clockwise standard rotation or counter clockwise rotation. The DF150AP is based on an inline four cylinder DOHC powerhead with a 2,867cm³ (174.9 cu.in.) displacement. While the large displacement contributes greatly to producing exceptional acceleration and torque, it doesn't mean that they are comparatively larger and heavier in size. On the contrary, Suzuki's engineers have targeted this big block motor to be one of the most versatile four strokes in the 150 HP class.
Unusually the Suzuki DF200 has a 55-degree V6 DOHC powerhead compared to the 60 degrees favoured by other outboard motor manufacturers. The engine is oversquare with a cylinder bore way larger than the piston stroke to reduce piston speeds at higher rpm and the 54amp voltage regulated alternator is under the flywheel eliminating the need for any belts.
To reduce gearcase torpedo diameter but still retain a reasonably deep reduction ratio, Suzuki opted for reduction gearing at the crankshaft in addition to the gearcase, pushing the powerhead weight farther forward and raising the combined ratio to a deep 2.29:1. This effectively converts engine torque to thrust at the prop and enables efficient coarse-pitch props to be swung without creating unnecessary hydrodynamic drag.
Powerhead access is good, with the fuel and engine oil filters easily reached and all wiring is neatly laid out as expected of a Japanese outboard. Valve clearance adjustment is needed only every 400 hours but requires removing the camshafts to set the shims, not an easy task. Surely the feeler gauge and spanner system adjustment of valve clearances would have been the better route, but all engine manufacturers have their own ideas of what works.
To reduce sump oil dilution that occurs with all four-stroke outboards during extended trolling periods, the sump capacity is a massive 8lt, 30 to 40 per cent larger than some of the competition. The Suzuki DF200 may have an SUV engine but it has been marinised well. Suzuki recommends its own Motul-made FCW (Four Cycle Watercooled) SAE 10W40 oil intended for all ambient temperatures.
Engine oil and filter changes are recommended every 100 hours or annually after the first 20 hours and providing this is done by an authorised Suzuki Outboards dealer, the recreational warranty is five years.
Maximizing Fuel Economy And Performance: With the launch of the new generation DF115A, our engineers have delivered a trio of outboards that offer great fuel economy without sacrificing on performance. This has been achieved by employing our advanced Lean Burn Fuel Control System.
Transferring Power Into Speed: Our in-line four cylinder outboards utilise aggressive gear ratios that enable these outboards to swing a larger prop. The combination of a large prop and lower gear ratio delivers plenty of torque, exhilarating acceleration and exciting top-end speed.
All Torque: With acceleration and manoeuvrability high on the list of priorities it is no surprise that the DF140, with its excellent power to weight ratio, was one of the models selected for use at the London 2012 Olympic & Paralympic Games Sailing Regatta.
Innovative Technology: The DF115A includes an O2 Sensor Feedback System that helps to keep emissions cleaner and more stable. In addition to this the DF140A and DF115A also benefit form a knock sensor that detects and controls abnormal combustion allowing the engine to operate at optimum performance.
Cleaner, More Efficient Operation: Suzuki utilizes a number of its advanced technologies to deliver cleaner, more efficient operation that conforms to the Recreational Craft Directive (RCD) – Directive 2003/44EC of the European Parliament and of the Council, and has received three-star ratings from the California Air Resources Board (CARB).
Maximizing Fuel Economy, Maximizing Performance: Recognizing a need for more fuel-efficient outboards, Suzuki developed and introduced its innovative Suzuki Lean Burn Control System on the DF90A/80A/70A outboards, which received great acclaim from boaters and the media alike. The system predicts fuel needs according to operating conditions allowing the engine to run on a more efficient fuel mixture through the use of a lean air to fuel ratio. Its benefits are delivered over a wide operating range providing significant improvements in fuel economy from low-speed operation up into the cruising range.
O2 Sensor Feedback Control System: Like Suzuki's flagship DF300AP, the DF140A/115A/100A feature an O2 Sensor Feedback Control system that keeps emissions cleaner and more stable. By controlling the air to fuel ratio across each of the engine's operating ranges, the system provides an optimum amount of fuel to the engine regardless of rpm.
DOHC 4-valve Engine: Suzuki has a long history of designing and manufacturing engines for motorcycle, automobile, and marine use. Drawing upon this unrivaled experience Suzuki engineers have designed an in-line four cylinder engine that delivers high power output, high performance, excellent fuel economy, and efficient operation. With a displacement of 2,044cm3, the in-line four-cylinder block is topped with a high performance 16-valve, dual overhead cam (DOHC) powerhead.
Obtaining Maximum Performance: The 115A utilizes an enhanced air intake system that maximizes airflow into the engine to obtain greater power output. In order for this system to achieve full potential, greater exhaust efficiency is required as well, so the engines are designed with an efficient "4 into 2 into 1" exhaust system that reduces drag in the exhaust letting it flow smoothly out of the cylinders. This design increases low to mid-range torque on these outboards and provides the wide powerband that boaters want. The 115A also features a two-stage reduction gear that delivers the torque needed to turn a large diameter propeller. This is normally done using larger gears or a larger gearbox, but Suzuki has long employed a two-stage system that provides the required torque without adding unwanted bulk or weight to the engine. With a final drive ratio of 2.59, these outboards produce plenty of torque for quick acceleration. It also features a two-stage reduction gear that delivers a larger gear ratio of 2.59. On the drive shaft, the first stage reduction delivers a ratio of 1.24 while the second stage, in the gear case itself, delivers a further reduction of 2.08. The biggest gain this system delivers is in its capability to use a highly efficient, large pitch, large diameter propeller.
Knock Sensor: The DF140A and DF115A are Suzuki's first four-cylinder outboards featuring a knock sensor. Found on some V6 models, this system is used to detect and control abnormal combustion allowing the engine to operate at optimum performance. The system increases engine durability and helps deliver maximum power.
Multi-point Sequential Electronic Fuel Injection: Multi-Point Sequential Electronic Fuel Injection is Suzuki's sophisticated fuel injection system found on Suzuki outboards from the DF40A to DF 300A. The system uses a 32-bit computer in the electronic control unit to monitor vital operating data gathered from a series of sensors located in critical areas on the engine. Processing this data in real time, the system automatically calculates the optimum amount and exact timing of fuel to be injected at high pressure into the combustion chamber. Benefits include smoother and faster acceleration, crisp throttle response, maximum fuel economy, low emissions, and quick, reliable starts.
Suzuki Water Detecting System: Water in the fuel can lead to problems that include poor combustion, lower power output, and corrosion. The Suzuki Water Detecting System is designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel. The filter also designed to let you check for water visually.
Suzuki Troll Mode System (optional): The Suzuki Troll Mode System is optionally available on all three outboards. This system provides finer control over engine speed at low rpms keeping the boat moving at a steady speed while trolling. When the system is engaged, engine speed is controlled with an independent control switch that adjusts engine revs in 50rpm increments over a range that spans from idle to 1,200rpm. In addition to the control switch, which can be mounted nearly anywhere on the console, the system includes a tachometer and is compatible with Suzuki's SMIS digital gauges or the dual scale analog gauges.
Technologies
Offset Driveshaft: Pioneered by Suzuki, the use of the offset drive shaft on four-stroke outboards has long been utilized to reduce the size of the outboard. Found on all Suzuki four-strokes from the DF70A and up, this design positions the crankshaft in front of the drive shaft simultaneously moving the outboard's center of gravity forward. While the design contributes greatly to the outboard's overall compactness and increased power performance, it also moves the engine's axis of inertia, the point where engine vibrations are at a minimum, up over the upper engine mount, thus greatly reducing vibration. These outboards also incorporate two-stage gear reduction designed to take maximum advantage of the power produced by these high-performance engines. Providing a final drive ratio of 2.50:1—the largest you can find in either of these outboard classes—it delivers powerful torque for quick acceleration and great top-end speed.
2-Stage Gear Reduction: This system which incorporates the Offset Driveshaft features a first stage reduction between the crankshaft and driveshaft, and a second stage reduction inside the gear case. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller. Advantage: High propulsive efficiency with large diameter propeller, Powerful navigation, maintaining propeller rotation even with a larger load and increased power to turn large diameter propellers, offering quick acceleration.
Lean Burn: Suzuki's innovative Lean Burn Control System was first introduced on the DF90A/80A/70A to great acclaim from boaters and the media alike. It predicts fuel needs according to operating conditions allowing the engine to run on a more efficient fuel mixture through the use of a lean air-fuel ratio. It delivers its benefits over a wide operating range, providing significant improvements in fuel economy from low-speed operation into the cruising range. Combining this system with the Suzuki Precision Control electronic throttle and shift system allows the operator precise control over engine RPM for improved fuel economy over a wider operating range. This combination also delivers smooth power transitions throughout the entire RPM range. In-house testing shows that while cruising, the DF300AP is 14% more economical than the original non-Lean Burn DF300 without sacrificing any power of the original DF300.
Self-Adjusting Timing Chain: Suzuki's self-adjusting timing chain is featured on the DF60A which is the first outboard in the 44.1kW (60PS) class equipped with this maintenance free feature. The chain is oil-bathed and features an automatic hydraulic tensioner that keeps the chain properly adjusted at all times for maintenance free operation.
Anti-Corrosion Finish: To guard against corrosion, Suzuki protects its outboards with its own specially formulated Suzuki Anti-Corrosion Finish. Applied directly to the outboard's aluminum alloy, this finish provides maximum bonding of the finish to the aluminum surface. Layering an epoxy primer undercoat, black metallic (or white) finish, and clear acrylic fiber finish on top of this forms an effective treatment against corrosion, protecting those parts of the outboard's aluminum alloy that are constantly exposed to saltwater.
Two-Way Water Inlet: The engine's cooling system relies on water supplied through low water intakes located on the lower unit. Utilizing this dual low water inlet configuration increases water flow into the lower unit, which delivers greater cooling efficiency. Positioning the forward inlet at the gear case nose delivers a greater water supply especially at high speeds. The second inlet is also positioned lower allowing the engine to operate in shallow water conditions.
Water Detecting System: Water in the fuel can lead to problems that include poor combustion, lower power output, and corrosion. The Suzuki Water Detecting System is designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel. The filter is also designed to let you check for water visually.
Tilt Limit System: A tilt limit system that prevents the outboard from tilting beyond a certain angle.

The DF6 brings 4-stroke performance and efficiency to portable outboards. Compact and lightweight, the DF6 is easy to transport and delivers surprising low- and mid-range torque for quick acceleration.
Knowing that small portables like the DF6 get transported a lot, we set out to design this outboard compact and lightweight to make transporting easier. Not to stop there, we added features that would make its operation easy and more user friendly. As four-strokes, the DF6 outboard deliver clean, economical operation, and being made by Suzuki, you know it delivers excellent power, performance, and durability.
Key Features
More Compact And Much Lighter: While maintaining the engine displacement of 138 cc, the conventional design has been overhauled and downsized to realize 1.0kg weight reduction (24.0kg). The lighter weight has improved operability. Along with weight reduction, the carrying handle integrated into the lower cover which has been rounded and made easier to hold, and an additional grip at the front further improve its portability.
Enhanced User-friendliness: The overhead integral fuel tank and the new lubricating systems allow transport and storage of the outboard on any of three sides (port, starboard, or front) without leakage of fuel or oil. Because the overhead fuel tank is placed right above the carburettor, it also allows gravity fuel supply, enabling the engine to start instantly right after filling fuel, even after long-term storage. These features have enhanced its user-friendliness as a portable outboard motor.
Lightweight: In addition to a reincarnated stylish appearance, the newly designed and developed Suzuki DF6A,DF5A and DF4A boast the unrivaled lightweight, 24.0Kg (S-shaft models). The lighter weight has improved portability as well as operability.
Outstanding Handle Operation: An ease of handling that has enjoyed great popularity. Further improvements to the tiller handle have successfully mitigated vibrations contributing to fatigue and stress when transmitted to the hand during operation. The DF6A, DF5A and DF4A particularly excel at vibration mitigation in the mid-range.
Offset Crankshaft: Positioning the crankshaft slightly off center of the cylinder reduces lateral pressure against the cylinder wall as the piston moves up and down in the cylinder. The result is smoother piston movement, which improves operating efficiency.
Easy After-storage Start: Because the integral overhead fuel tank and one-way valve allow gravity fuel supply, the engine can be started without opening the engine cover, even after long term storage.
Quiet Operation: The low noise level is the result of a silencer, designed to optimize the capacity and shape of the air intake. The new design of the rocker arm and the plane bearing of the crankshaft also help reduce the noise level. We also changed the structure of the parts related to the rocker arm and eliminated its excessive play. In addition, we changed the crankshaft bearing from a common ball type to a plane type.
Highly Reliable Lubricating System: The forced lubrication system of the DF6A, DF5A and DF4A has an additional oil passage to the upper and lower crankshaft and connecting rod big end. The addition of a first-in-its-class** oil filter greatly increases the reliability of the lubricating system. Furthermore, the new position of the oil window allows for visual confirmation of the actual lubricating condition.
Three-way Storage: The new fuel and lubricating systems allow extremely convenient storage of the outboard on any of three sides (port, starboard or front) without worrying about the storage orientation.
Improved Portability Inner Handle: The carrying handle integrated into the lower cover has been rounded and made easier to hold.
Improved Portability Outer Handle: An additional grip at the front of the lower engine cover provides the convenience of carrying the outboard with both hands.
New Tilt System: The tilt system of the DF6A, DF5A and DF4A offers different up-and-down paths of the shallow drive arm compared with the previous models. When raised, it can be locked at three positions. When lowered, it can just be smoothly moved to its lowest position without locking.
Suzuki's Anti Corrosion System: Suzuki protects its outboards with an anti-corrosion finish specially developed by Suzuki. Applied directly to the aluminum surface it maximizes the bond between the finish and the surface, increasing the protection and durability of parts that are constantly exposed to saltwater.
Lower Emissions, Efficient Operation: Suzuki’s advanced four-stroke technologies deliver highly efficient operation and lower emissions. This allows Suzuki outboards to conform to some of the world’s strictest standards including the EURO 1 Emissions Standards (Directive 94/25/EC as amended by Directive 2003/44/EC), and receive a three-star rating from the California Air Resources Board (CARB).

The NEW DF200A Four-Cylinder delivers the kind of impressive performance you expect only from a V6 Engine – But from just four cylinders, meaning it is much lighter and more efficient.
Suzuki's NEW DF200A inline four-cylinder outboard motor stands to redefine lightweight outboard performance and fuel economy by delivering advanced features, enhanced reliability and impressive power on par with a V6 engine. At just 226kg, the new DF200A is more than 12% lighter than Suzuki's V6 DF200. Even so, it produces the same 147kW (200PS) of power to offer boaters the choice of a lighter, leaner, more compact solution that comes without any compromises.
Go Lean, Go Green, Go Suzuki.
Key Features
Semi-direct Air Intake System: A specially designed cowl and semi-direct air intake system were designed to provide cooler air to the tuned long-track intake manifold while a four valve per cylinder DOHC powerhead with Variable Valve Timing lets the engine breathe more efficiently increasing acceleration and top end speed. Added to that are a fuel injection system and Suzuki's Lean Burn Technology for improved fuel economy.
Big Block High Performance Engine: With the DF200A, our goal was to build an outboard that provides all of the power and performance of a 147kW (200PS) class V6 outboard using a lighter, more compact four-cylinder configuration. To deliver that level of performance our engineers used an inline four-cylinder engine with a 2.9-liter "Big-Block" displacement and a higher 10.2:1 compression ratio to generate impressive acceleration and low-end torque.
Resonator: The engine's exhaust system is a well-known source of engine noise, but another, often overlooked source is the intake manifold. Air being sucked into the intake manifold at high velocities can generate a harsh sound. The DF200A incorporates an air intake resonator that reduces such noise keeping operation exceptionally quiet.
Suzuki Lean Burn Control System: The Suzuki Lean Burn Control System is an intelligent fuel delivery system that achieves remarkable improvements in fuel consumption making fuel-efficient four-stroke outboards even more economical. Monitoring engine performance and operating conditions in real time, the system uses the 32-bit onboard ECM to predict fuel needs and deliver a leaner, more precise fuel mixture across the outboard's operating range. The results show significant improvements in fuel economy across the entire powerband, including the cruising range where the engine is used a majority of the time. Comparing the new DF200A with the original V6 DF200, tests show up to a 19% increase in fuel efficiency mainly in the cruising range (around 70% of its maximum speed).
Suzuki Multi Stage Induction (MSI): Getting the right amount of air into the cylinder has a great impact on performance. High-speed operation typically requires a greater volume of air, low-speed less. Suzuki's Multi-Stage Induction system meets these needs by utilizing two intake manifold pipes per cylinder to ensure the engine gets the right amount of air. At low rpm, air enters the combustion chamber through a longer, curved manifold pipe designed to improve combustion and improve low-end torque. As rpm increases, the valves open on the direct intake pipes. Shorter and lacking resistance, these pipes allow a greater volume of air into the chamber, increasing the engine's ability to breathe efficiently at high rpm resulting in higher power output during high-speed operation.
Quiet Operation: Suzuki four-stroke outboards have long been noted for their exceptionally quiet operation. Suzuki engineers go to great lengths incorporating methods designed to keep outboard operation as quiet as possible. In a noise comparison test between the DF200A and a competing 147kW (200PS) in-line four-stroke outboard, the results clearly show that the DF200A runs quieter than its competitor.
Suzuki Selective Rotation: Large boats equipped with multi-outboard installations generally pair a standard rotation outboard with a counterrotation model to keep the boat traveling in a straight line and on an even keel. Once requiring the purchase of a dedicated counter-rotation model, Suzuki's innovative Suzuki Selective Rotation eliminates that need by incorporating a special, unified design of gears, shaft, and bearings in the lower unit that allow the outboard to operate reliably and efficiently in either direction. Available only on the DF200AP, counter-rotation operation requires an optional activation switch that connects to a circuit inside of the engine compartment plus the installation of a counter-rotation propeller.
Suzuki Precision Control (Electronic Throttle And Shift System): Only available with the DF200AP version, Suzuki Precision Control is a computer-based throttle and shift system that replaces mechanical control cables with a digital fly-by-wire system to eliminate friction and resistance in the controls. The system provides smooth and precise control along with crisp, immediate shifting which are particularly helpful during low rpm operation and when maneuvering. Combined with Suzuki's Lean Burn Control System, the system also helps to improve fuel efficiency over a wide operating range. Suzuki Precision Control also features safeguards that help protect the engine and drive against damage due to mishandling and is compatible with single, twin, or triple installations as well as dual station operation.
Dual Engine Flush Ports: Over time, salt, sand, and dirt buildup can restrict flow in the cooling system causing damage. To help prevent such buildup, both outboards are equipped with two freshwater flush ports that make flushing the cooling system as easy as possible. With one port located on the port side of the down housing and a second on the front panel, you'll always have easy access to the flushing system whether the boat is in or out of the water.

Offset Driveshaft: Pioneered by Suzuki, the use of the offset drive shaft on four-stroke outboards has long been utilized to reduce the size of the outboard. Found on all Suzuki four-strokes from the DF70A and up, this design positions the crankshaft in front of the drive shaft simultaneously moving the outboard's center of gravity forward. While the design contributes greatly to the outboard's overall compactness and increased power performance, it also moves the engine's axis of inertia, the point where engine vibrations are at a minimum, up over the upper engine mount, thus greatly reducing vibration. These outboards also incorporate two-stage gear reduction designed to take maximum advantage of the power produced by these high-performance engines. Providing a final drive ratio of 2.50:1—the largest you can find in either of these outboard classes—it delivers powerful torque for quick acceleration and great top-end speed.
2-Stage Gear Reduction: This system which incorporates the Offset Driveshaft features a first stage reduction between the crankshaft and driveshaft, and a second stage reduction inside the gear case. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller. Advantage: High propulsive efficiency with large diameter propeller, Powerful navigation, maintaining propeller rotation even with a larger load and increased power to turn large diameter propellers, offering quick acceleration.

Shorter and lacking resistance, these pipes allow a greater volume of air into the chamber, increasing the engine's ability to breathe efficiently at high rpm resulting in higher power output during high-speed operation.
VVT - Variable Valve Timing: Suzuki's engineers designed the 4.0-liter V6 engine with an aggressive cam profile that delivers maximum output and performance at high rpm. In coupling this cam profile with Suzuki's advanced Variable Valve Timing (VVT), the DF300AP/250AP delivers the additional torque that outboards need for accelerating in the low to mid-range. VVT achieves this by adjusting the timing of the intake valves, allowing them to open before the exhaust valves are fully closed, creating a momentary overlap in the timing where both sets of valves are open. Using VVT, this overlap can be increased or decreased by altering intake timing with the camshaft resulting in optimum timing for low and mid-range operation.
Lean Burn: Suzuki's innovative Lean Burn Control System was first introduced on the DF90A/80A/70A to great acclaim from boaters and the media alike. It predicts fuel needs according to operating conditions allowing the engine to run on a more efficient fuel mixture through the use of a lean air-fuel ratio. It delivers its benefits over a wide operating range, providing significant improvements in fuel economy from low-speed operation into the cruising range. Combining this system with the Suzuki Precision Control electronic throttle and shift system allows the operator precise control over engine RPM for improved fuel economy over a wider operating range. This combination also delivers smooth power transitions throughout the entire RPM range. In-house testing shows that while cruising, the DF300AP is 14% more economical than the original non-Lean Burn DF300 without sacrificing any power of the original DF300.
Self-Adjusting Timing Chain: Suzuki's self-adjusting timing chain is featured on the DF60A which is the first outboard in the 44.1kW (60PS) class equipped with this maintenance free feature. The chain is oil-bathed and features an automatic hydraulic tensioner that keeps the chain properly adjusted at all times for maintenance free operation.
Anti-Corrosion Finish: To guard against corrosion, Suzuki protects its outboards with its own specially formulated Suzuki Anti-Corrosion Finish. Applied directly to the outboard's aluminum alloy, this finish provides maximum bonding of the finish to the aluminum surface. Layering an epoxy primer undercoat, black metallic (or white) finish, and clear acrylic fiber finish on top of this forms an effective treatment against corrosion, protecting those parts of the outboard's aluminum alloy that are constantly exposed to saltwater.
Selective Rotation: In multi-outboard installations on large boats, a counter-rotation outboard is usually paired with a regular rotation model to help keep the boat traveling on an even keel and in a straight line. The DF300AP/250AP is built with special counter rotating gearing in the lower unit, which causes the prop to rotate in the opposite direction. Suzuki Selective Rotation eliminates the need to purchase a dedicated counter-rotation outboard by using a special switch that when connected to a circuit inside of the engine compartment, turns a regular rotation outboard into a counter-rotation model with a counter rotational propeller. This industry first is made possible through a special, unified design of gears, shaft, and bearings in the lower unit that are designed to operate reliably and efficiently in either regular or counter-rotation directions.
Precision Control: Only available with the DF200AP version, Suzuki Precision Control is a computer-based throttle and shift system that replaces mechanical control cables with a digital fly-by-wire system to eliminate friction and resistance in the controls. The system provides smooth and precise control along with crisp, immediate shifting which are particularly helpful during low rpm operation and when maneuvering. Combined with Suzuki's Lean Burn Control System, the system also helps to improve fuel efficiency over a wide operating range.

When the system is engaged, engine speed is controlles with an independent control switch that adjusts engine revs in 50 rpm increments over a range that spans from idle to 1200 rpms. In addition to the control switch, wich can be mounted nearly anywhere in the console, the system includes a tachometer and s compatible with Suzuki's SMIS digital gauges ot the dual scale analog gauges.

Suzuki's DF150AP incorporates the Drive by Wire Suzuki Precision Control System for easy, smooth and precise throttle and shift operation. The AP model also incorporates Suzuki Selective Rotation which enables the outboard to operate in either clockwise standard rotation or counter clockwise rotation. The DF150AP is based on an inline four cylinder DOHC powerhead with a 2,867cm³ (174.9 cu.in.) displacement. While the large displacement contributes greatly to producing exceptional acceleration and torque, it doesn't mean that they are comparatively larger and heavier in size.

Award-winning and exciting outboards, precision engineered to give you the power and performance you need, when you need it. The DF250AP is based on the DF300AP and shares the same award winning innovations and designs of Suzuki's flagship outboard. Advanced features like Suzuki Selective Rotation, Suzuki Precision Control and Suzuki Lean Burn Control, plus big V6 power combine to provide boaters with outstanding performance and great convenience. Go with a Proven Winner, Go Suzuki!
NEW SUZUKI SELECTIVE ROTATION
In addition to our drive-by-wire system (Suzuki Precision Control) and the Lean Burn Control System, the DF250AP feature Suzuki's Selective Rotation. In its standard form, the outboard will operate in regular clockwise rotation, using the forward gear. Now, by changing the gear-shift mode and adding a counter rotational propeller, the same outboard can operate in counter rotation mode (anti-clockwise).
In counter rotation mode the power is transmitted through the reverse gear, which has been changed to give it the same characteristics as the forward gears. This is a world first in outboard motor technology. PROVEN TECHNOLOGY
By using our advanced technologies these V6 outboards deliver superior performance. They have dual overhead cam (DOHC) powerheads with four valves per cylinder and multi-point sequential electronic fuel injection. The 55° V-block design and offset driveshafts contribute to making them remarkably compact. The DF250AP delivers high performance with our Variable Valve Timing (VVT), by maximising torque in the low/mid-range. Features may include:
If an engine with performance is an essential part of your boating life, then you need our combination of quality, reliability and choice. The Suzuki DF140A is light and compact while providing exceptional performance, easily giving this motor the best power-to-weight ratio in its class. An engine cover design features a large air induction port to provide maximum airflow and thus, maximum power. It’s also the first 4-stroke to utilize an oil cooler, ensuring that all that horsepower is available under every condition. Added up, the DF140A provides heavy-duty performance and long-lasting durability in a lightweight package. Go Lean, Clean, and Green. Go Suzuki!
Cleaner, More Efficient Operation
Suzuki utilizes a number of its advanced technologies to deliver cleaner, more efficient operation that conforms to the Recreational Craft Directive (RCD) – Directive 2003/44EC of the European Parliament and of the Council, and has received three-star ratings from the California Air Resources Board (CARB).
Maximizing Fuel Economy & Performance
With the launch of the new generation DF140A, DF115A and DF100A, our engineers have delivered a trio of outboards that offer great fuel economy without sacrificing on performance. This has been achieved by employing our advanced Lean Burn Fuel Control System. Transferring Power Into Speed
Our in-line four cylinder outboards utilise aggressive gear ratios that enable these outboards to swing a larger prop. The combination of a large prop and lower gear ratio delivers plenty of torque, exhilarating acceleration and exciting top-end speed. All Torque
With acceleration and manoeuvrability high on the list of priorities it is no surprise that the DF140, with its excellent power to weight ratio, was one of the models selected for use at the London 2012 Olympic & Paralympic Games Sailing Regatta. Innovative Technology
The DF140A, DF115A and DF100A include an O2 Sensor Feedback System that helps to keep emissions cleaner and more stable. In addition to this the DF140A and DF115A also benefit form a knock sensor that detects and controls abnormal combustion allowing the engine to operate at optimum performance.
O2 Sensor Feedback Control System
Like Suzuki’s flagship DF300AP, the DF140A/115A/100A feature an O2 Sensor Feedback Control system that keeps emissions cleaner and more stable. By controlling the air to fuel ratio across each of the engine’s operating ranges, the system provides an optimum amount of fuel to the engine regardless of rpm.
DOHC 4-Valve Engine
Suzuki has a long history of designing and manufacturing engines for motorcycle, automobile, and marine use. Drawing upon this unrivaled experience Suzuki engineers have designed an in-line four cylinder engine that delivers high power output, high performance, excellent fuel economy, and efficient operation. With a displacement of 2,044cm3, the in-line four-cylinder block is topped with a high performance 16-valve, dual overhead cam (DOHC) powerhead.
Obtaining Maximum Performance
The DF140A/115A/100A utilize an enhanced air intake system that maximizes airflow into the engine to obtain greater power output. In order for this system to achieve full potential, greater exhaust efficiency is required as well, so the engines are designed with an efficient “4 into 2 into 1” exhaust system that reduces drag in the exhaust letting it flow smoothly out of the cylinders. This design increases low to mid-range torque on these outboards and provides the wide powerband that boaters want. The DF140A/115A/100A also feature a two-stage reduction gear that delivers the torque needed to turn a large diameter propeller. This is normally done using larger gears or a larger gearbox, but Suzuki has long employed a two-stage system that provides the required torque without adding unwanted bulk or weight to the engine. With a final drive ratio of 2.59, these outboards produce plenty of torque for quick acceleration. Both models also feature a two-stage reduction gear that delivers a larger gear ratio of 2.59. On the drive shaft, the first stage reduction delivers a ratio of 1.24 while the second stage, in the gear case itself, delivers a further reduction of 2.08. The biggest gain this system delivers is in its capability to use a highly efficient, large pitch, large diameter propeller.
Knock Sensor (DF140A/115A)
The DF140A and DF115A are Suzuki’s first four-cylinder outboards featuring a knock sensor. Found on some V6 models, this system is used to detect and control abnormal combustion allowing the engine to operate at optimum performance. The system increases engine durability and helps deliver maximum power. Multi-Point Sequential Electronic Fuel Injection
Multi-Point Sequential Electronic Fuel Injection is Suzuki’s sophisticated fuel injection system found on Suzuki outboards from the DF40A to DF 300A. The system uses a 32-bit computer in the electronic control unit to monitor vital operating data gathered from a series of sensors located in critical areas on the engine. Processing this data in real time, the system automatically calculates the optimum amount and exact timing of fuel to be injected at high pressure into the combustion chamber. Benefits include smoother and faster acceleration, crisp throttle response, maximum fuel economy, low emissions, and quick, reliable starts.
Suzuki Water Detecting System
Water in the fuel can lead to problems that include poor combustion, lower power output, and corrosion. The Suzuki Water Detecting System is designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel. The filter also designed to let you check for water visually.
Suzuki Troll Mode System (Optional)
The Suzuki Troll Mode System is optionally available on all three outboards. This system provides finer control over engine speed at low rpms keeping the boat moving at a steady speed while trolling. When the system is engaged, engine speed is controlled with an independent control switch that adjusts engine revs in 50rpm increments over a range that spans from idle to 1,200rpm. In addition to the control switch, which can be mounted nearly anywhere on the console, the system includes a tachometer and is compatible with Suzuki’s SMIS digital gauges or the dual scale analog gauges.
Multi Function Tiller Handle (Optional)
Available on the DF115A and DF100A only, Suzuki’s Multi-Function Tiller handle is ergonomically designed using computer modeling to simulate the operator’s body, arm, and eye movements to optimize placement of the shift lever, switches, and indicator and provide easier, more comfortable control of the outboard. The shift lever is also ergonomically designed to provide a comfortable feel whether it’s operated with the left or right hand. The power trim and tilt switch is located on the handle grip allowing simultaneous operation of the throttle and trim and the handle also incorporates a Suzuki Troll Mode System switch.

Mounted on a Cruise Craft Outsider 625 and pushing a total of 1800kg, including three adults, the demo Suzuki DF200 outboard provided plenty of top-end speed with relaxed and frugal midrange cruising. It started instantly hot or cold with no oil smoke appearing and providing the antiventilation plate was kept at least three-quarters immersed, power astern with the massive 16 x 20in Suzuki stainless steel prop was very good. The remote-control box had a positive yet smooth shifting operation.
Idling along, only a slight tremor ran through the Cruise Craft Outsider 625 and above 1000rpm there was absolutely no vibration, so if you want flab reduction the Suzuki DF200 definitely isn’t the way to go. Holeshot was good but the engine really came alive over 3000rpm. When I floored the throttle lever from these revs my unsuspecting co-tester Richard Ardizzone was thrown clear across the cockpit to the stern lounge. Thank God there was one!
Running at 3000rpm the hull was fully planing and this rpm would be ideal for long offshore runs returning excellent midrange fuel efficiency. The forte of any four-stroke engine is midrange rpm efficiency and the Suzy didn’t disappoint.
Through tight turns at 4000rpm with the leg trimmed in there was no prop ventilation, just steep hull banking common to all deep-vee hulls. At or near wide open throttle the Suzy was so quiet we could all talk normally at the helm.
THE VERDICT Valve clearance complications aside, the V6 Suzuki DF200 outboard motor is well designed and engineered and with scheduled maintenance and regular freshwater flushing should provide years of trouble-free enjoyment. Its massive piston displacement is the largest of all the 200hp outboards, so the engine is completely under-stressed. It won’t reduce flab but neither will it encourage tinnitus!
Unusually the Suzuki DF200 has a 55-degree V6 DOHC powerhead compared to the 60 degrees favoured by other outboard motor manufacturers. The engine is oversquare with a cylinder bore way larger than the piston stroke to reduce piston speeds at higher rpm and the 54amp voltage regulated alternator is under the flywheel eliminating the need for any belts.
To reduce gearcase torpedo diameter but still retain a reasonably deep reduction ratio, Suzuki opted for reduction gearing at the crankshaft in addition to the gearcase, pushing the powerhead weight farther forward and raising the combined ratio to a deep 2.29:1. This effectively converts engine torque to thrust at the prop and enables efficient coarse-pitch props to be swung without creating unnecessary hydrodynamic drag.
Powerhead access is good, with the fuel and engine oil filters easily reached and all wiring is neatly laid out as expected of a Japanese outboard. Valve clearance adjustment is needed only every 400 hours but requires removing the camshafts to set the shims, not an easy task. Surely the feeler gauge and spanner system adjustment of valve clearances would have been the better route, but all engine manufacturers have their own ideas of what works.
To reduce sump oil dilution that occurs with all four-stroke outboards during extended trolling periods, the sump capacity is a massive 8lt, 30 to 40 per cent larger than some of the competition. The Suzuki DF200 may have an SUV engine but it has been marinised well. Suzuki recommends its own Motul-made FCW (Four Cycle Watercooled) SAE 10W40 oil intended for all ambient temperatures.
Engine oil and filter changes are recommended every 100 hours or annually after the first 20 hours and providing this is done by an authorised Suzuki Outboards dealer, the recreational warranty is five years.
