2027 Yamaha Four Stroke Portable Heavy Load F15SEHA

Meet the Yamaha Four Stroke Portable Heavy Load F15SEHA—a compact outboard that’s all about doing real work while still being easy to live with. Finished in classic Yamaha Gray, this engine looks right at home on everything from practical utility skiffs to compact fishing rigs, and it’s sized perfectly for small hulls that want confident push without jumping to a bulky powerplant.
At 15 bhp (11.2 kW) at 5500 RPM, this 2-cylinder, 4-stroke in-line design delivers the kind of usable torque that small boats appreciate most—especially “heavy load” setups like a jon boat with a full cooler, a couple of anglers, and gear, or a tender that regularly hauls supplies. The 2.08:1 gear ratio helps translate that power into strong propeller bite, giving you better authority getting on plane (or just pushing steadily) when the boat is weighted down.
Because it’s a 4-stroke that runs on regular gas, it’s a smart choice for owners who care about sensible fuel use at cruise and day-to-day practicality. The SOHC valvetrain with 4 valves (2 per cylinder) and a 9.3:1 compression ratio are all aimed at smooth, efficient performance—ideal for longer idle-to-cruise runs around marinas, coves, and backwaters.
This model is built for real marine conditions, too: it’s salt water capable, cooled by water (open loop), and backed up with an engine alert system (visual/audible) plus emergency RPM reduction for extra peace of mind when you’re far from the ramp. Starting is simple with electric start, and the onboard 10-amp alternator helps keep your battery supported while you’re out exploring.
Rigging stays straightforward with a 15-inch shaft, tiller steering, and manual trim with 4 trim positions, so you can dial in the running angle for shallow spots, varying loads, or changing chop. And at just 111 lb dry, it’s a genuinely manageable option for portability and repowers where weight matters.
This is an engine-only listing—perfect for powering the right small hull with Yamaha reliability in a clean, timeless Yamaha Gray package. Warranty coverage varies by program and region; contact the dealer for current Yamaha warranty details for this model.
