Tohatsu MFS3.5 Portable Outboard Motor 2024 – 3.5HP Four Stroke

Tohatsu MFS3.5 2024: More Push, Same Featherweight Package

The 2024 Tohatsu MFS3.5 takes the same 86cc (5.2 cu in) single-cylinder four stroke that powers the MFS2.5 and tunes it to 3.5 HP (2.6 kW) — meaningfully more thrust for headwinds, current, and a passenger aboard, at essentially the same carry weight. Ergonomic front and rear handles, an integral fuel tank, full 360° tiller steering for reverse thrust, and shallow water drive round out a genuinely grab-and-go package. For most buyers weighing the two, the MFS3.5 is the smarter buy in the small portable class.

Benefits & Applications

The extra horsepower matters most when you’re loaded or fighting wind — for tenders, inflatables, canoes, jon boats, and sailboat auxiliary duty. Compare the Tohatsu MFS2.5 2024 or rivals like the Mercury 3.5 HP 2024. Bigger block: Tohatsu MFS4 2024.

Frequently Asked Questions

Is the MFS3.5 the same engine as the MFS2.5?

Same 86cc block — the MFS3.5 is tuned for higher output, so you gain thrust without meaningful extra weight.

Which shaft length should I choose?

A 15-inch short shaft suits most dinghies and tenders; choose the 20-inch long shaft for sailboats and higher transoms.

Does it have a reverse gear?

No — 360° tiller steering rotates the engine to provide reverse thrust.
