Yamaha F4SMHA – 4HP Short Shaft Outboard Motor For Sale

When you need a step up in power without sacrificing portability, the Yamaha F4SMHA delivers. This 4 HP Yamaha outboard motor for sale packs 4 horsepower at 5500 RPM into a compact, 59-lb package — making it one of the most popular portable outboards among freshwater anglers, canoe and kayak fishermen, and tender owners who need more push than a 2.5 HP can provide. The 15″ short shaft makes the F4SMHA a perfect match for low-transom aluminum fishing boats, jon boats, and inflatables where extra pushing power is needed without the weight or cost of a midrange engine.

Built on Yamaha’s proven 4-stroke platform, the F4SMHA runs on regular unleaded fuel with no pre-mixing required — making it cleaner, quieter, and more economical than comparable 2-stroke designs. Fuel consumption is impressively low for a 4 HP outboard, which translates to more time on the water between fill-ups. The tiller handle delivers direct, responsive steering — smooth, reliable, and intuitive for solo operators. Starting is effortless with Yamaha’s reliable pull-start system, and the compact powerhead design means the engine stores easily in tight boat compartments.
