Suzuki’s Fuel-Efficient, High Performance, New Generation DF40
In 2011, Suzuki announced the launch of new fuel-efficient and high performance four stroke outboard motors – the new generation DF40. The new model boast a host of technical features that combine to give them increased fuel efficiency and performance, while weighing less and fitting more compactly on the transom – all of which are qualities that today’s boaters are demanding.

Not surprising that Suzuki has been honoured with a prestigious Innovation Award at the 2011 Miami International Boat Show for its new DF40 outboard motors. The award was made on February 17, by the National Marine Manufacturers Association (NMMA) and Boating Writers International (BWI), recognizing the DF40 as the most innovative new products in the Outboard Engines Category.
Starting is a breeze, with Suzuki’s Easy Start System. Turn the key once and the engine automatically turns over, coming to life at your command. Once underway, Suzuki’s advanced Lean Burn Control technology takes full advantage of sensors monitoring engine performance and ambient environmental conditions. Using this input, the Lean Burn Control accurately predicts engine needs to provide the fuel injection system with just the right mixture of air and fuel, delivering optimal fuel efficiency.
Initial tests have shown that these new generation outboards use 27% less fuel than thecurrent 40 models, mainly in the cruising range, which is where the engine is used for the majority of the time.
These new outboards are based on the Suzuki’s proven in-line three-cylinder dual overhead cam (DOHC) 12-valve engine with a highly efficient air intake system, which comes into effect in the high RPM range. With 941 cm3 of displacement, multi-point sequential electronic fuel injection, these engines respond quickly and confidently to every move of the throttle, particularly when accelerating from cruising speeds. All of this technology combines to provide quiet and efficient operation as well as exhilarating performance. For example, the Suzuki engineers are pleased to report that the new DF40 is 6% faster in their top speed and 25% quicker in acceleration than the current Suzuki models.
When designing these new engines, Suzuki’s engineers also paid close attention to durability. Internal oil flow is more efficient, keeping moving parts better lubricated while using less energy. These new engines also feature Suzuki’s maintenance-free oil-bathed timing chain, which will give boaters years of dependable service. This is the first time this feature has ever been offered in the 40 horsepower class.
The compact size and light weight of the new DF40 make them an ideal power match for a wide variety of boats, including; FRP pleasure boats, fishing boats, small RIBs and aluminium boats. In particular these new outboards will be ideal for entry level boating.
Suzuki is proud to have been chosen the sole supplier of marine outboard motors to the London 2012 Olympic & Paralympic Games Sailing Regatta, with the all-new DF40 being one of the models used for this prestigious event.
