2027 Yamaha Four Stroke Portable Heavy Load F25SWTHC

$5,800

Description

Meet the 2027 Yamaha F25SWTHC—a portable, heavy‑load‑ready outboard that brings big confidence in a compact package. Finished in classic Yamaha Gray, this engine looks right at home on hardworking transoms and weekend adventure rigs alike—and it’s being offered here as an engine-only listing for repower or new install (not a complete boat).
With 25 hp (18.7 kW) at 5500 rpm from a 432 cc inline 2‑cylinder four‑stroke, the F25 delivers the kind of punch that suits small to mid-size tiller-steered hulls—think utility skiffs, jon boats, inflatables, and other lightweight fishing or work platforms that benefit from strong low‑to‑midrange pull. Matched to a 2.00:1 gear ratio, it’s set up to convert that power into practical thrust, helping a load-carrying hull climb onto plane (or push efficiently in displacement mode) without feeling strained.
Because it’s fuel injected and runs on regular gasoline, the F25 is built for easy ownership and strong fuel economy at a comfortable cruise. The four‑stroke design and SOHC, 4‑valve breathing (2 valves per cylinder) are all about clean, consistent power delivery—ideal for long runs between spots and steady-speed trolling without constant fiddling.
This model is also ready for real marine duty: it’s salt water capable and uses water (open loop) cooling to keep temperatures stable when you’re working the engine in hot weather or pushing into chop. For peace of mind, Yamaha’s visual/audible engine alert system and emergency RPM reduction add a smart layer of protection when conditions (or maintenance intervals) aren’t perfect.
Rigging and handling are straightforward for hands-on boaters. You get tiller steering, a power trim system with 4 trim positions, and the flexibility of electric or pull starting—a nice combo for both convenience at the dock and backup capability on the water. This configuration is a 15-inch shaft model and carries a manageable 126 lb (57 kg) dry weight, making it a solid choice for portable-minded owners who still want true heavy-load capability.
