2027 Yamaha Four Stroke Portable Heavy Load F25SMHC

Meet the 2027 Yamaha F25SMHC—a Yamaha Gray portable four-stroke outboard that’s built to turn small-boat days into big-boat confidence. This is an engine-only listing (no boat included), perfect for repowering a lightweight to mid-weight hull where smart torque, easy handling, and dependable efficiency matter most.
With 25 hp (18.7 kW) at 5500 RPM, this 2-cylinder, in-line four-stroke is a sweet spot for 15" transom setups on boats that like to plane quickly and stay comfortable at cruise—think utility skiffs, jon boats, compact fishing rigs, and small inflatables that need real push without stepping into heavy, oversized power. The 432 cc displacement and SOHC 4-valve design help it deliver strong, usable pull through the midrange, while the 2.00:1 gear ratio is well-suited to swinging a prop efficiently for loaded runs, current, or working duty.
Fuel stops shouldn’t be the highlight of your day on the water. This F25 uses fuel injection and runs on regular gas, which helps keep cruise fuel economy practical and predictable—especially for anglers and explorers who rack up hours at steady throttle. Cooling is water (open loop), and it’s salt water capable, making it a solid choice whether your weekends are spent on inland lakes or coastal bays.
The portable mindset continues with a straightforward pull start, and the tiller steering keeps control simple and direct. At 126 lbs dry (15-inch shaft), it’s substantial enough to feel planted on the transom but still in the realm of manageable for small-boat owners. Dial in your running attitude with the manual trim system offering 4 trim positions, letting you adapt to changing loads or chop without complication.
For peace of mind underway, Yamaha includes a visual/audible alert system plus emergency RPM reduction, helping protect the engine when conditions demand attention. And with a 16-amp alternator, you’ve got useful charging capability to support your on-board electrical needs while you cruise.
If you’re looking for a dependable, salt-ready, efficient Yamaha Gray F25 to power a compact hull with confidence, this 2027 Yamaha F25SMHC is ready to go. Warranty coverage varies—ask our team for the details available on this engine.
