MFS20EEFS
Marine Specialist Insight: The Tohatsu MFS20EEFS (MPN MFS20EEFS) is the pinnacle of portable 20 HP performance. Utilizing Tohatsu's award-winning Battery-Less Electronic Fuel Injection (EFI), this 15-inch short shaft motor delivers exceptional torque and top-end speed without the maintenance burden of a carburetor. Featuring Electric Start with a manual backup, it is the ideal power choice for larger inflatables, aluminum fishing boats, and heavy-duty tenders that require reliable, clean-burning power.
Lightweight Power with EFI Precision
The Tohatsu MFS20EEFS (MPN: MFS20EEFS) offers a class-leading power-to-weight ratio. The 333cc twin-cylinder engine is designed to provide immediate throttle response and a significantly smoother idle than traditional carbureted models. Because the EFI system is "battery-less," you enjoy all the benefits of digital fuel injection—such as automatic altitude compensation and easy cold starts—regardless of your battery’s state of charge.
This model is equipped with a multi-function tiller handle, which integrates the gear shift, throttle control, and steering tensioner for ergonomic, one-handed operation. The MFS20EEFS also features Tohatsu’s optimized center of gravity, making it easier to tilt and transport than other 20 HP motors in its class. With a high-output 12A charging system, it provides ample power for your fish finders and GPS units while underway.
