MFS15

PORTABLE

We do our best to provide you with the best engine we possibly can. That’s why we have taken our 15 hp model and made it better by introducing our MFS15hp Electronic Fuel Injection (EFI) which is the lightest 4-stroke battery-less EFI 15hp model in the industry! You can enjoy added features such as a higher power-to-weight ratio, which is the most important factor for small horsepower outboards. We also succeeded in drastically reducing sound level and vibration on our new 15hp EFI outboard. One major advantage of the EFI system is a quick startup with no choke needed and provides crisp acceleration throughout all RPM ranges as well as a significantly increased fuel efficiency at wide open throttle. Go ahead; put the engine to the test! You won’t regret it!

Power Tilt! We’ve added Power Tilt to our remote steering/throttle models to provide you even greater operating convenience. This engine offers the same features as our standard 15hp EFI model plus an added power tilt feature for greater operating convenience. As with our other engines, you can count on it to deliver the same reliability our reputation was built on.

FEATURES

Multi-Function Tiller Handle

Stop Switch, Front Shift, Friction Adjusting Screw and Power Tilt Switch (PTS: on power tilt models only) are integrated into the tiller handle for convenience.

Stowable Carrying Handle

We’ve incorporated a carrying handle on the front that can easily be tucked away when not in use.

Fuel Water Separator

A high quality, user-friendly fuel water separator is standard equipment on all EFI 20 | 15 | 9.9 motors. This unique yet simple fuel water separator doesn’t require the use of a single tool to drain the water.

Center of Gravity Improved

By moving heavy components (i.e. crankshaft, driveshaft) 30mm forward compared to the previous model, the tilting weight has decreased by 26% from the previous version, making it much easier for users to tilt manually.

Compact Fuel System Layout for Easy Maintenance

The Vapor Separator Tank (VST) has been designed to integrate the high pressure fuel feed pump, regulator, and fuel cooler into one component.
