2020 Yamaha 15 HP F15SMHA Outboard Motor

Tiller steering and a pull-cord manual start keep this 2020 Yamaha F15SMHA simple: 15 hp from two cylinders, new, weighing 111 lbs. Carbureted at 362cc, its full-throttle rpm range runs from 5000 up to 6000.

Who it suits

A manual-start tiller motor is the simplest version of this engine, with no electrical system to look after, which fits boats where low weight and few moving parts matter more than push-button convenience. One person can generally mount or remove it without a hoist.

Before you order

A transom that is taller than this shaft length allows will leave the lower unit too shallow, which hurts cooling and steering together, so line up the 15-inch shaft with the boat's actual transom before ordering. This carbureted engine also benefits from fuel being drained or stabilized before extended storage.

Keeping it running

Because there is no charging system, the only electrical component to think about is the ignition itself; most upkeep on a motor like this comes down to fresh fuel, a clean spark plug, and the usual gearcase oil change on schedule. That short parts list is part of the appeal for owners who service their own small outboard rather than hauling it to a shop.

Common questions
