2027 Yamaha Four Stroke Portable Light F4LMHA

Meet the 2027 Yamaha F4LMHA Four Stroke Portable Light outboard in classic Yamaha Gray—a small engine with big “let’s go explore” energy. This is an engine-only listing (not a complete boat), perfect for giving the right hull the right kind of power without adding unnecessary weight or complexity.
With 4 bhp (3 kW) at 4500 RPM from a 139cc, single-cylinder, 4-stroke OHV design (2 valves), the F4 is a great match for lightweight small craft that don’t need brute force—think tenders, small inflatables, canoes, and compact utility boats where predictable thrust matters more than top-end speed. That 2.08:1 gear ratio helps translate the engine’s power into confident prop bite, so you get useful push for docking, shoreline runs, and steady cruising.
Because it’s a four-stroke running on regular gas with carburetion, this Yamaha is built for the kind of efficient, easygoing operation small-boat owners appreciate—especially at typical cruise speeds where you’re just covering water smoothly rather than running wide open. Cooling is handled by water (open loop), keeping temperatures in check out on the water.
It’s also designed with real-world portability in mind. At a 61 lb dry weight and with a 20-inch shaft, it’s a solid fit for many small transoms that call for a long-shaft setup. Steering is simple and direct with a tiller, and the manual trim system offers 5 trim positions, letting you dial in running angle for different loads and conditions. Starting is straightforward via pull start, and there’s a 6-amp alternator for basic charging support while you’re underway.
Best of all, it’s salt water capable, making it a smart choice for coastal tenders and harbor hopping. If you’re looking for a clean, dependable portable outboard in Yamaha Gray that’s sized right for small hulls and built to sip fuel at cruise, the F4LMHA is ready to be the little engine behind your next on-the-water mission.
