Tohatsu Outboards has taken their 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.

Tohatsu also succeeded in drastically reducing sound level and vibration on the new 15hp EFI outboard. Major advantages of the EFI system is  quick startup with no choke needed, crisp acceleration throughout all RPM ranges, as well as a significantly increased fuel efficiency at wide open throttle.

As with all Tohatsu Outboards, you can count on it to deliver the same reliability their reputation was built on. Go ahead; put the engine to the test! You won’t regret it! Free Shipping!

Multi-Function Tiller Handle

Stop Switch, Front Shift, Friction Adjusting Screw and Power Tilt Switch (if equipped) are integrated into the tiller handle
for convenience and ease of operation.

Stowable Carrying Handle

Tohatsu 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 Design for Easy Maintenance

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