The new Suzuki DF90 is the first and only outboard in its class to feature a self-adjusting oil bath timing chain instead of traditional belts. Automatic hydraulic tensioners ensure it is correctly tensioned at all times, minimizing maintenance. This Suzuki outboard motor uses Lean Burn fuel saving technology - which predicts fuel demand depending on operating conditions and allows the motor to run on a very lean fuel mixture. Special developments have significantly reduced the noise and vibration of the motor. It also features a tilt angle limiter designed to protect your boat from damage.
 
A POWERFUL DESIGN.
Twelve years after starting the four-stroke revolution, with its award winning DF70 and DF60 outboards, Suzuki has reinvented the category again with the DF90A. The first of Suzuki’s new generation of four-strokes, the DF90A is a showcase of advancements and achievements – like digital sequential electronic fuel injection, a powerful 2.59:1 final drive ratio, and a zero-maintenance self-adjusting time chain. All of this comes in addition to Suzuki’s Lean Burn Control System, and newer models also sport the optional Suzuki Troll Mode System.
BE IN THE KNOW
The DF90A hosts digital sequential electronic fuel injection, meaning it reads the electronic control unit monitors throttle setting, engine RPM, cylinder wall and air-intake temperature and atmospheric pressure all at once. All of these considerations cause the fuel injection to enter the combustion chamber at the most optimal opportunity. The benefits are smoother and faster acceleration, crisp throttle response and quick, reliable starting, no matter what the temperature is.
DON’T SCARE THE FISH
Glide into your favorite fishing honeyhole with Suzuki’s Troll Mode System. The engine’s revs can be adjusted in 50 rpm intervals by simply pressing the Troll Mode control switch from idle up to 1200 rpm, giving you control over your wake and speed.
