Yamaha F20 20HP Portable Mechanical ES Outboard – Reliable & Compact

The Yamaha F20 Portable Mechanical ES Outboard Motor is a versatile, reliable, and compact engine designed for small boats, dinghies, inflatables, and auxiliary craft. Yamaha’s engineering ensures that this 20-horsepower outboard combines power, portability, and fuel efficiency in a user-friendly design suitable for both recreational and practical applications.

What It Is:
The F20 is a 20HP, two-cylinder, four-stroke outboard with a mechanical electronic shift (ES) system. Weighing approximately 97 lbs (44 kg), it is portable and easy to mount while delivering robust performance for small and mid-sized watercraft.

How It Works:
Equipped with a 366cc engine, the F20 features Yamaha’s mechanical ES system, which allows smooth gear shifting and enhanced control over speed and maneuverability. Its manual start with optional electric start ensures reliable ignition, while the tiller handle provides precise steering. The engine’s wet-sump lubrication and overhead valve (OHV) design offer durability and quiet operation.
