Yamaha 20HP F20SMHB Tiller Manual 15in Shaft

The Yamaha 20HP F20SMHB is a high-performance 432cc two-cylinder outboard featuring a 15-inch short shaft and traditional manual recoil start. As one of the lightest 20-horsepower outboards in its class, it utilizes Yamaha’s innovative battery-less Electronic Fuel Injection (EFI) to provide effortless starting and smooth, fuel-efficient performance without the weight of a battery. Its mechanical soul is defined by pure portability and torque density, making it the premier choice for aluminum fishing boats and inflatable tenders that prioritize weight savings and reliable, clean-burning power.

Focused on superior operational durability, the F20SMHB is shielded by specialized anodic protection and Yamaha’s multi-layered anti-corrosion system to combat the rigors of high-salinity marine environments. The ergonomic tiller handle features a forward-mounted shift lever and an easy-access stop switch for comfortable, intuitive control. Maintenance is simplified through a front-mounted freshwater flush port and conveniently located service points. This model includes a robust 16-amp alternator, ensuring sufficient power to support basic navigational lighting and electronics even in a manual-start configuration.
