Tohatsu 9.8HP MFS9.8BS Outboard Motor

This spec listing covers the Tohatsu 9.8HP MFS9.8BS in its manual-start form: a 15-inch shaft, no electric starter, weighing 82 lbs, the lightest version of this engine sold under this exact model code.

Manual start, short shaft

Dropping electric start removes the alternator and charging hardware from the build, which is why this configuration comes in lighter than motors that keep that hardware. The 15-inch shaft keeps it suited to boats with a shorter transom rather than a tall one. Two cylinders displace 209cc through a single carburetor, with full throttle between 5000 and 6000 rpm, numbers shared across this whole engine family regardless of starter type.

Deciding if this is the right configuration

Choose this one if you're comfortable with a pull-start and don't need onboard charging from the outboard itself; choose an electric-start model instead if you want push-button starting or plan to run electronics off an alternator. Weight savings and fewer moving parts are the trade for giving up that convenience. Warranty on this unit runs 5 years from Tohatsu, the same term carried across this engine's whole lineup regardless of configuration.

Does this version include a charging system? No, that's reserved for electric-start models.

What's the shaft length? 15 inches.

Is this fuel injected? No, a single carburetor feeds both cylinders on this engine.

What's the starting method? A manual pull cord, with no electric-start hardware fitted.
