Tohatsu 9.9HP | MFS9.9EEFS

The Tohatsu 9.9HP MFS9.9EEFS takes the EFI, 333cc engine from this family and puts it on a 15-inch shaft, weighing around 104 lbs with electric start. It's the short-shaft route into fuel injection for boaters who don't need a long-shaft motor's extra reach.

Short shaft meets fuel injection

A 15-inch shaft suits boats with a shorter transom, and pairing it with EFI rather than a carburetor means more consistent starting without choke adjustments, particularly useful on small boats that get started and stopped often through a day on the water. Full throttle runs between 5400 and 6100 rpm on this twin-cylinder four-stroke, noticeably more revs than the carbureted engines sold under a different displacement in this catalog.

What's included

A built-in alternator keeps a charging circuit live once the motor is running, handy for basic electronics aboard a small boat. Hardware in the box runs to a propeller, a 3.1-gallon tank with fuel line, a tool kit, a lanyard cutoff, and an owner's manual on top of that charging hardware. Tohatsu's warranty runs 5 years on this unit, the same term applied across its outboard range, carbureted or fuel-injected, and worth confirming before any work that might affect coverage.

How short is this one's shaft? 15 inches, matched to a lower-transom boat.

Is a manual-start backup included? This listing lists electric start only.
