Suzuki's Lean Burn Control System

Suzuki’s innovative Lean Burn Control System was first introduced on the DF90A/80A/70A to great acclaim from boaters and the media alike. It predicts fuel needs according to operating conditions allowing the engine to run on a more efficient fuel mixture through the use of a lean air-fuel ratio. It delivers its benefits over a wide operating range, providing significant improvements in fuel economy from low-speed operation into the cruising range. Combining this system with the Suzuki Precision Control electronic throttle and shift system allows the operator precise control over engine RPM for improved fuel economy over a wider operating range. This combination also delivers smooth power transitions throughout the entire RPM range. In-house testing shows that while cruising, the DF300AP is 14% more economical than the original non-Lean Burn DF300 without sacrificing any power of the original DF300

Multi Stage Induction

Suzuki’s Multi-Stage Induction system is used to increase engine performance. Each cylinder in this system is equipped with a set of short and long intake manifolds that are utilized in relation to engine speed. At lower rpm the longer pipes deliver an optimum volume of fresh air into the chamber, improving combustion and boosting low-end torque. At higher rpm, the valve on the shorter, direct intake pipe opens up letting air in the chamber directly boosting high-speed power output. (DF250W/250/225)

Advanced Features Only Found On The DF200AP*2

* 2 : DF200AP production is scheduled to start in February 2015.

Suzuki Selective Rotation

Large boats equipped with multi-outboard installations generally pair a standard rotation outboard with a counterrotation model to keep the boat traveling in a straight line and on an even keel. Once requiring the purchase of a dedicated counter-rotation model, Suzuki’s innovative Suzuki Selective Rotation eliminates that need by incorporating a special, unified design of gears, shaft, and bearings in the lower unit that allow the outboard to operate reliably and efficiently in either direction.
Available only on the DF200AP, counter-rotation operation requires an optional activation switch that connects to a circuit inside of the engine compartment plus the installation of a counter-rotation propeller*3.
