2018 Tohatsu 20 Hp MFS20ES Outboard Motor

The 2018 Tohatsu MFS20ES is the short-shaft version of the manual-start, EFI 20 hp line, built with a 15-inch shaft, tiller steering, and rope starting eased by a decompression device. Like its long-shaft sibling, it carries no alternator since there's no electric starter for one to support, which keeps the motor's wiring about as simple as a modern EFI engine gets.

Short shaft, manual start

Choose the 15-inch shaft only if your transom height calls for it; shaft length should follow the boat, not your preference for manual or electric start. This EFI engine's full-throttle range covers 5,000 to 6,000 rpm.

Fuel and equipment

Expect roughly 3 gallons of capacity, near 12 liters, from the tank that ships with this motor, piped through its own hose rather than borrowed from another model. An aluminum propeller is included, the manual and tool kit ship apart from the tank, and the engine is cleared for saltwater use without any extra prep.

Q: Can I add a battery charging option later? The listing doesn't include an alternator for this version; confirm with us before assuming one can be retrofitted.

Tohatsu backs the MFS20ES with a 5-year warranty. Rope starting means less to go wrong electrically, so most of the long-term upkeep here comes down to fuel quality, plug condition, and keeping the cooling passages clear.
