2020 Yamaha 15 HP F15SEHA Outboard Motor

Weighing in at 117 lbs, the 2020 Yamaha F15SEHA sends 15 hp through two cylinders and a 15-inch shaft, steered by tiller, started with a button. Fuel passes through a single carburetor into 362cc of displacement, and full throttle lands between 5000 and 6000 rpm.

Before you order

Running a short shaft on a transom built for a longer one means the lower unit never gets deep enough, hurting cooling and control alike, so confirm the boat's transom measures right for this 15-inch shaft before ordering. There is no way to correct this after the fact short of changing the shaft itself.

Who it suits

Tiller steering paired with electric start suits a small boat where the operator sits near the motor and wants push-button starting without a console rig. At 117 lbs, mounting and removing it is manageable for one person without a hoist or extra hands, and the carbureted fuel system keeps the whole setup mechanically simple.

Upkeep to plan for

Expect the usual carbureted-engine routine: fresh fuel each season, a stabilizer if the motor sits over winter, and a battery kept charged so the electric start is ready when needed. Owners switching from a manual pull-start motor usually notice the convenience right away, along with the small added duty of keeping that battery topped off.
