2019 Yamaha 8 HP F8SMHB Outboard Motor

Built on a 15-inch shaft rather than the longer option Yamaha offers on this platform, the 2019 Yamaha F8SMHB is an 8 hp two-cylinder four-stroke weighing 87 lbs. The F8SMHB runs a carbureted 212cc block with a 9.46:1 compression ratio and a 12-volt, 6-amp alternator.

Who it suits

Smaller aluminum boats, inflatables and dinghies with a lower transom are the fit for the F8SMHB's 15-inch shaft, and the twin-cylinder design keeps the whole package light enough to carry by hand between a boat and a vehicle rather than hoisting it with gear. Its wet-sump lubrication also means no separate oil mixing before each outing.

Before you order

The F8SMHB ships with manual starting, though an electric starter kit is available as an option if you would rather not pull-start it. Confirm 15 inches is correct for your transom, since Yamaha also sells a longer-shaft version of this same engine under a separate listing.
