In-Line Four Stroke

PERHAPS THE MOST VERSATILE OUTBOARDS ON THE WATER.

There's a reason why the compact, lightweight F150 is our best-selling outboard. Actually there are a lot of reasons. Flats boats. Deck boats. Offshore boats. Pontoons. Deep-V hulls. The F150 is a perfect choice for so many boats, delivering the power and acceleration of a 150hp two-stroke - in a clean, quiet, fuel-efficient four stroke. If your boat calls for less horsepower, the F115 gives you outstanding performance and versatility, in a suitably lighter package.

• LESS ENGINE VIBRATION. Twin Counter Balancer Shafts on the F150 minimize engine vibration for a smooth, pleasant boating experience.
• THE UNIQUE 10MM OFFSET CRANKSHAFT on the F150 provides greater intake volume, and four Tuned Intake Tubes increase low- and midrange torque, boosting acceleration.
• GREATER POWER AND RELIABILITY. The 16-Valve Double Overhead Cam not only maximizes power by using four valves per cylinder, but also eliminates rocker arms and their adjustments. Increased air supply and volumetric efficiency also increase performance.
• EXCEPTIONAL PERFORMANCE. Electronic Fuel Injection is controlled by the ECM (Engine Control Module), continually adjusting the fuel/air mix to properly match engine load and speed.
