Tohatsu has introduced a new Electronic Fuel Injection (EFI) four-stroke outboard engine to its range; the 9.9 horsepower EFI Sport. The lightest outboard in its class delivers incredible torque and top speed, getting you there fast. The battery-free EFI system on the MFS9.9 offers superior starting performance compared to previous carbureted models. In addition, with the EFI outboard, there is no need for a choke button when starting, and you will notice smooth and rapid acceleration throughout the entire rev range.

We set out to completely redesign an already successful engine, and we have exceeded that goal. Tohatsu’s new 9.9 EFI Sport model is at the top of the list in terms of top speed, idle fuel consumption and, most importantly, fuel efficiency at full throttle. Our fuel efficiency offers 50% more range than the competition***.

So what are you waiting for, get the 9.9 horsepower EFI Sport and Enjoy the Wind!
The 9.9 horsepower EFI is available in three different shaft lengths: 15”, 20” and 25”. Tohatsu’s 9.9 horsepower offers a great option for boats: Power Trim! Our 9.9 horsepower EFI engine is way ahead of the competition with the 4-blade high-thrust propeller found on power trim models. With Tohatsu’s 9.9 horsepower and now a power trim option with electronic fuel injection, why would you want to try anything else?
