DF40

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.

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.
