Yamaha F4 (F4 Series)

The Yamaha F4 strikes the sweet spot between featherweight portability and practical everyday power. Four horsepower is the ideal output for small aluminum tinnies, inflatable pontoons, and lightweight fiberglass runabouts — enough to maintain a comfortable planning speed while remaining easy to handle on and off the water.

Yamaha’s refined four-stroke engine technology gives the F4 smooth, quiet operation and excellent fuel economy compared to older two-stroke designs. The robust tiller handle provides direct, responsive steering, while the reliable recoil start system means you’re never far from getting underway. A neat, symmetrical design keeps the motor balanced during transport and mounting.
