2021 Tohatsu 20hp, EFI 4-Stroke

Now available on remote steering/ throttle models, the new 20hp Power Tilt is ideal for inflatable, small fishing and pontoon boats. The uniquely designed engine improves functionality and convenience with its light and compact power tilt and transom bracket. Now you can tilt your motor out of the water with just a push of a button. Simplify your boating experience with this new power tilt model.

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 MFS20 Electronic Fuel Injection (EFI) which is the lightest 4-stroke battery-less EFI 20hp 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 20hp 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!
