Suzuki’s 4-stroke technology delivers clean, efficient operation that conforms to the Ultra-Low Emissions 3-Star rating from the California Air Resources Board (CARB).

Exceptional features such as forged one-piece crankshaft, stainless steel water pump, race-proven 4-into-2-into-1 exhaust system, computer-controlled fuel injection and painstaking attention to detail ensure that your Suzuki DF140 will continue to deliver optimum performance at almost any throttle setting, temperature or altitude. We make propulsion hassle-free so you can concentrate on having fun.

Our DF140 incorporates a number of features that help to guard the outboard against exposure to the elements. Suzuki Anti-Corrosion Finish is specially formulated to protect parts of the aluminum exterior that are constantly exposed to e elements. Other features that increase the outboard's durability include forged pistons treated with an Alumite coating for increased heat resistance and a resin coating on the piston skirt for improved resistance to wear and friction reduction, and a water-cooled voltage regulator in the outboard’s electrical system.

From the first second you power up the DF140 you’ll recognize the power and precision of a well-designed machine. Digital ignition reacts without hesitation. The engine runs quietly and smoke-free. And performance is nothing short of total technological harmony.

An engine cover design features a large air induction port to provide maximum airflow and thus, maximum power.  

Suzuki's engine management system controls every aspect of the DF's engines performance. It also allows for a much more accurate control of the operation of the outboard and minimizes human error. Today's outboards are no longer purely mechanical, performance has improved dramatically by the incorporation of computer technology. The Suzuki engine management system controls the engine ignition system and provides the ideal fuel supply under all operating conditions making adjustments for engine wear and ensuring optimum performance throughout the life of the motor. It also enables engine safeguards to be incorporated such as over rev limiter, oil change reminder system and enables servicing to be simplified by using a plug-in diagnostic programme on a lap top computer to interrogate the inbuilt engine management module.

The Suzuki DF140 is light and compact while providing exceptional performance, easily giving this motor the best power-to-weight ratio in its class.

Suzuki pioneered the use of Multi Point Sequential Electronic Fuel Injection in four-stroke outboards with the introduction of the award winning DF70 and DF60. Found on all models from the DF40 and up, the system utilizes an ECM (Engine Control Module) that constantly monitors crucial data in real time, from a comprehensive network of critically placed sensors. Using this data the ECM instantly calculates the optimum amount of fuel to be injected at high pressure into the cylinders by the Multi Point Sequential Electronic Fuel Injection system. The system delivers lower fuel consumption, reduced exhaust emissions, smoother starts, crisper acceleration, smoother performance, and maximum efficiency.

Suzuki set the standard with the use of an offset driveshaft with the original DF90. Effective at reducing the size of the outboard it also moves the outboard’s center of gravity forward for better weight distribution. Found on all models from the New Generation DF70 and greater, it also provides improvements in power performance, balance, and vibration reduction.

It's also the first 4-stroke to utilize an oil cooler, ensuring that all that horsepower is available under every condition.

At idle, only the tell tale water jet will assure you that the motor is running. Very low noise allows you to talk normally to your passengers or crew when out on the water. Add to this very little engine vibration and you have peace and quiet to go along with a great day on the lake.

Suzuki uses its own, original Suzuki Anti-Corrosion Finish to guard the outboard against the harmful effects of corrosion. This special formula is applied directly to the outboard’s aluminum surface to provide maximum bonding of the finish to the alloy surface. Layered on top are an epoxy, primer undercoat, black metallic finish, and clear acrylic resin finish that together, form an effective treatment against corrosion.

Suzuki builds in convenient features that add to the quality of your boating experience. Among those features are a tilt limit switch to prevent the motor from tilting past a preset limit as well as dual engine flush ports for easy flushing of the cooling system.
