Suzuki DF300 4 Stroke Outboard

 

The DF300 takes advantage of many of the same sophisticated technologies proven in our other V6 4-stroke outboards. Performance enhancing features include a dual overhead cam (DOHC) powerhead with 4-valves per cylinder, Suzuki’s Variable Valve Timing (VVT), and multi-point electronic fuel injection. Other features found on the DF300 include a narrow 55° V-block design, offset driveshaft, and two-stage gear reduction which help make the DF300 compact and sleek.

 

Suzuki’s 4-stroke technology delivers clean, efficient operation that conforms to EURO 1 Emissions Standards and an Ultra-Low Emissions 3-Star rating from the California Air Resources Board (CARB).

 

A large air induction port contributes to the DF300’s high power output by maximizing airflow into the engine. Increased airflow results in greater low- to mid-range torque to provide the wide powerband that outboards need. It also includes a water separator that aids in keeping water out of the electronic throttle body, and a heat shield to keep intake air as cool as possible.

 

The DF300 incorporates a number of features that help to guard the outboard against exposure to the elements. Suzuki Anti-Corrosion Finish is specially formulated to protect parts of the aluminium exterior that are constantly exposed to saltwater. Dual engine flush ports make flushing of the engine as easy as possible. Other features that increase the DF300’s durability include forged pistons treated with an Alumite coating for increased heat resistance and a resin coating on the piston skirt for improved resistance to wear and friction reduction, and a water-cooled voltage regulator in the outboard’s electrical system.
