Specifications subject to change without notice.

This outboard comes in a variety of configurations. We have short 15" and long 20" shafts available, manual start and electric start models that feature a 12V charging system. We even have an ultra long 25" shaft for you sail boaters!

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 MFS9.9hp Electronic Fuel Injection (EFI) which is the lightest 4-stroke battery-less EFI 9.9hp 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!
