2017 Tohatsu 9.8 HP MFS9.8BEFL Outboard Motor

This 2017 Tohatsu 9.8 HP MFS9.8BEFL runs a 20-inch long shaft with tiller steering and electric start, built for transoms that need the extra reach. Tohatsu's own spec sheet puts it at 90.4 lbs, a two-cylinder four-stroke displacing 209 cc with carbureted fuel delivery and a wet-sump oiling system. It is a straightforward match for sailboats needing auxiliary push, and for jon boats, skiffs or inflatables set up for a long-shaft motor.

Controls and fit to confirm

Tiller steering has an adjustable friction setting, trim and tilt are manual, and the shift lever is mounted up near the cowl rather than on a console, giving forward, neutral and reverse. Full throttle falls between 5,000 and 6,000 rpm. Measure your transom height against the 20-inch shaft before ordering; getting this length wrong changes how deep the propeller rides.

Running and upkeep

Cooling is water-based and thermostatically controlled, the engine is rated for saltwater, and ignition runs on a digital CD system. Oil capacity is 27 fl. oz. of SAE 10W-30 or 10W-40. A three-blade aluminum wheel ships already mounted, along with the external fuel tank and its quick-connect line, so there's little to assemble beyond bolting the motor to the boat.

Does it need a separate battery? No battery is built into the motor; electric start draws off your boat's own battery.

What's the listed weight? Tohatsu's own numbers put this unit at 90.4 lbs, the figure repeated across its spec sheet.
