Suzuki has announced the launch of two new fuel-efficient and high performance four stroke outboard motors – the new generation DF40A and DF50A.
The new models were unveiled at the Miami International Boat Show and 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.
Suzuki's Lean Burn Control technology uses sensors to monitor 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 two new generation outboards use 23 percent less fuel than the current 40 and 50 models, mainly in the cruising range, which is where the engine is used for the majority of the time.
Both of these new outboards are based on the Suzuki's in-line three-cylinder dual overhead cam (DOHC) 12-valve engine with an air intake system, which comes into effect in the high RPM range.
With 941 cubic-centimetres of displacement and multi-point sequential electronic fuel injection, these engines respond quickly when accelerating from cruising speeds.
According to Suzuki, the new DF50 is six percent faster in their top speed and 26 percent quicker in acceleration than the current Suzuki models.
These new engines feature Suzuki's maintenance-free oil-bathed timing chain, which is the first time this feature has been offered in the 40 and 50 horsepower class.
The compact size and light weight of the new DF40 and DF50 are suited 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.
The new engines should reach Australian and New Zealand shores around August 2010.
