Suzuki’s latest 40 & 50hp models

Suzuki has announced the launch of its new generation DF40A and DF50A four-stroke outboard engines.

The new models boast a host of technical features that Suzuki said combine to give them increased fuel efficiency and performance, while weighing less than ever before and fitting more compactly on the transom.

One of the features include 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 is claimed to accurately predict engine needs to provide the fuel injection system with just the right mixture of air and fuel and deliver optimal fuel efficiency.

Suzuki claim initial tests have shown that these two new generation outboards use 23 per cent 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 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 are said to respond quickly and confidently to throttle movement, particularly when accelerating from cruising speeds.

Suzuki engineers claim the new DF50 is six per cent faster in top speed and 26 per cent quicker in acceleration than the current Suzuki models.

These new engines also 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 make them an ideal power match for a wide variety of boats.

The new engines should reach Australian and New Zealand shores around August 2010.
