2027 Yamaha Four Stroke Portable Heavy Load F20SWB

Meet the Yamaha Four Stroke Portable Heavy Load F20SWB in classic Yamaha Gray—an engine-only listing built for boaters who want real-world muscle without the bulk. This 20 hp (14.9 kW) in-line twin is a sweet spot for small aluminum fishing rigs, utility/jon boats, inflatables, and compact skiffs that need dependable push with confident low-end torque for passengers, gear, and “one more cooler” days. With 20 bhp on tap at 5500 RPM and a 5000–6000 RPM full-throttle range, it’s tuned to get a lightweight-to-midweight hull up and moving efficiently, then settle into an easy cruise.
The 432 cc displacement, 9.3:1 compression ratio, and SOHC 4-valve layout (2 valves per cylinder) give this four-stroke a responsive feel when you roll into the throttle—exactly what you want when working in current, maneuvering around docks, or nudging a loaded boat onto plane. Fuel injection keeps things consistent, and it runs on regular gas, making everyday operation simple and wallet-friendly at cruise.
Built for the marine environment, open-loop water cooling and salt-water capability help this outboard feel at home on lakes, rivers, and coastal runs. You’ll also appreciate the peace of mind that comes from a visual/audible engine alert system plus emergency RPM reduction—smart protection when conditions (or distractions) happen.
This F20SWB is a 15-inch short-shaft model, a common match for many portable and small transoms, and it weighs in at 126 lbs dry—solid and stable without being overbearing. Starting is flexible with electric start or pull start, and charging support comes via a 16-amp alternator for keeping onboard electronics happier. Power transfers through a propeller with a 2.00:1 gear ratio, while manual trim with four positions lets you dial in running angle for your load and water conditions. Remote steering control rounds out the setup for clean, confident helm integration.
Stop in and let’s make sure your hull is paired to the right shaft length and setup—this Yamaha Gray F20 is ready to be the hardworking heart of your next season.
