Yamaha F9.9SMHB2 – 9.9HP Short Shaft Outboard Motor For Sale

The 9.9 HP 4 stroke outboard motor (F9.9SMHB2) represents a significant step up from the 6 HP class — delivering nearly double the power in a design that remains compact enough for smaller boats and manageable enough for transport without a full motor bracket. This 9.9 HP Yamaha outboard motor for sale produces its rated horsepower at 5500 RPM through Yamaha’s proven 4-stroke single-cylinder powerhead, giving you the smooth, consistent power delivery that Yamaha portable outboards are internationally known for. At 87 lbs with a 15″ short shaft, the F9.9SMHB2 is an excellent match for small aluminum fishing boats, jon boats, and inflatable tenders where extra pushing power is essential.

The “B2″ designation marks an updated design series with refined carburetion and improved cold-start performance over earlier 9.9 HP Yamaha models. Boaters who previously ran 9.9 HP 2-strokes will notice an immediate improvement in fuel economy and a dramatic reduction in exhaust smoke when switching to the F9.9SMHB2 — benefits that compound into significant savings over a full season of regular use. The tiller handle provides immediate throttle and gear response, and the 15” shaft keeps the engine compact enough for boats where transom space is at a premium.
