2027 Yamaha Four Stroke Portable Heavy Load F20LMHB

Meet the Yamaha F20LMHB—a new, portable 20 HP four-stroke outboard that’s built to turn a wide range of small-boat days into easy days. Finished in classic Yamaha Gray, this engine looks right at home on everything from a sturdy utility jon to a heavier-loaded skiff, inflatable, or small sailboat that wants dependable push without the bulk of a larger powerplant. (This listing is for the engine only, not a complete boat.)
At the heart of this F20 is a 432cc in-line 2-cylinder four-stroke with SOHC and 4 valves total (two per cylinder). That displacement is the secret sauce for the “heavy load” feel: you get confident low- and mid-range muscle for getting on step, carrying extra gear, or punching through a stiff breeze—exactly the kind of real-world torque that pairs well with light to mid-size hulls that need practical thrust more than bragging rights. Rated at 20 bhp (14.9 kW) at 5500 RPM, it sits in the sweet spot for boats that want lively acceleration and a comfortable cruise without feeling overworked.
Because it’s fuel injected and runs on regular gas, the F20LMHB is designed for simple ownership and efficient cruising. Dial in your speed, let the prop do the work, and enjoy the kind of fuel economy that makes longer runs, more exploring, and more time on the water feel like the obvious plan.
Marine-ready details show up where they matter: water (open loop) cooling, salt water capable construction, and a smart protection package that keeps you informed and protected—an engine alert system (visual/audible) plus emergency RPM reduction if conditions demand it.
Rigging is refreshingly straightforward. You get tiller steering control and a manual trim system with 4 positions to help match the boat’s attitude to load and water conditions. Power is delivered through a propeller with a 2.00:1 gear ratio, and this model comes in a 20-inch shaft—a common fit for many transoms in this class. Starting is simple and reliable with a pull starter, and there’s a 16-amp alternator to support onboard electrical needs.
