2027 Yamaha Four Stroke Portable Heavy Load F25LWTHC
Description
Meet the 2027 Yamaha F25LWTHC Four Stroke portable outboard in classic Yamaha Gray—a smart, hard-working engine-only upgrade for the boater who wants reliable push without stepping up into bulky horsepower. This is a standalone marine engine listing (not a boat), ready to be matched to the right hull and put to work.
With 25 hp (18.7 kW) at 5500 RPM from a 432cc, 2-cylinder in-line 4-stroke, this F25 is a sweet spot for boats that need confident torque and control rather than sheer top-end speed. It’s a great fit for many light-to-midweight 20" transom rigs—think utility skiffs, small center consoles, inflatables, jon boats, and kicker/aux applications where a strong midrange and predictable handling matter. The 2.00:1 gear ratio helps translate that power into practical thrust at the prop, so getting on plane (or staying efficiently on step) feels more effortless than the horsepower number alone suggests.
At cruise, the fuel-injected fourstroke design is all about smooth, consistent fueling—especially handy when conditions change or you’re hopping between idle zones and open stretches. It sips regular gas, and the fourstroke cycle is built for efficient, confidence-inspiring run time when you’re using your boat the way most people actually do: cruising, exploring, and working a shoreline without constantly thinking about the fuel dock.
This outboard is also designed with real-world rigging and usability in mind. You get electric start with pull backup, plus tiller steering for straightforward control. Dial in your running attitude with a power trim system offering 4 trim positions, helping you adjust for passenger load, chop, or a lighter solo setup. And because boating doesn’t always give second chances, Yamaha includes a visual/audible alert system with emergency RPM reduction to help protect the engine when something needs your attention.
Built to run where boaters run, it’s salt-water capable and uses water (open loop) cooling. Output for accessories is supported by a 16-amp alternator, and the 20-inch shaft configuration pairs cleanly with many common transoms. Dry weight is a manageable 143 lbs, keeping portability and repower flexibility firmly in the “yes” column.
