Priced To Sell! Inventory Units Only Boasting the honor of the lightest weight outboard in its class, Tohatsu’s newly designed MFS 20hp Electronic Fuel Injection (EFI) is a great choice for a wide variety of boaters. Just because it is lighter in weight than our previous 20hp four stroke, doesn’t mean this model won’t deliver the same level of performance. This 20hp battery-less electronic fuel injection four stroke has exceptional torque and top end speed, with low vibration. We chose to build an EFI outboard because it has easy startup with no choke required and smooth, crisp acceleration throughout all RPM ranges. Another added benefit of an EFI versus our previous carbureted outboard is the fuel efficiency at wide open throttle, which allows you to go up to 50% farther on less fuel.
