Yamaha F20SMHA – 20HP Short Shaft Outboard Motor For Sale

The Yamaha F20SMHA marks a significant leap in the Yamaha portable outboard lineup — delivering 20 horsepower at 5500 RPM from a robust 4-stroke powerhead that is still compact enough to be classified as a portable engine. This 20 HP Yamaha outboard motor for sale is purpose-built for boaters who need real performance power without committing to a fixed midrange installation. At 114 lbs with a 15″ short shaft and tiller control, the F20SMHA is an ideal primary motor for 14 to 17-foot aluminum fishing boats, inflatable boats, and light fiberglass hulls with low-profile transoms that need genuine push — not just enough power to idle around.

What sets the F20SMHA apart from smaller portable outboards is its multi-cylinder 4-stroke architecture, which delivers a noticeably smoother, more refined power delivery at all throttle settings. The extra displacement and cylinder count give the F20SMHA strong mid-range torque, excellent fuel economy relative to output, and the kind of consistent, reliable starting performance that Yamaha 4-stroke engines are known for. Whether you are trolling for striped bass on Long Island Sound, running across a freshwater lake to your favorite fishing spot, or pushing a fully loaded inflatable through a light chop, the F20SMHA handles it with confidence.
