2027 Yamaha Four Stroke Portable Heavy Load F15SMHA

Meet the 2027 Yamaha F15SMHA in classic Yamaha Gray—an engine-only solution that’s ready to turn a wide range of small boats into go-anywhere, do-anything rigs. This portable four-stroke outboard is built around a 362cc in-line twin, and that displacement is the secret sauce: you get the kind of confident low- and mid-range push that lighter, smaller blocks can’t always deliver. For 14–16' aluminum fishing boats, utility skiffs, small tenders, and other lightweight hulls in the 15-hp class, this motor is a sweet spot—enough horsepower to get up and go, and the torque to stay happy when the boat is loaded with gear, a cooler, or a second passenger.
At wide open throttle, the F15 is designed to run in the 5000–6000 RPM range (rated 15 bhp at 5500 RPM), giving you the flexibility to dial in performance with the right prop and load. A 2.08:1 gear ratio helps translate that power into solid bite at the propeller—exactly what you want when you’re pushing off a beach, maneuvering around docks, or working in current.
As a four-stroke that sips regular gas, it’s an easy engine to live with for long days on the water. Cruise along for a shoreline hop, a slow troll back to the ramp, or a run across the lake—either way you’re getting efficient four-stroke operation without needing anything exotic at the pump.
This model keeps things simple and dependable: pull starting, tiller steering control, and manual trim with four trim positions to help you match the engine angle to your hull and conditions. Cooling is water (open loop), and it’s salt-water capable, making it equally at home on the bay or the backwaters.
And because peace of mind matters offshore and on the lake, Yamaha builds in an engine alert system with visual/audible warnings plus emergency RPM reduction to help protect the powerhead when something’s not right.
With a 15-inch shaft and an impressively manageable 111 lb dry weight, the F15SMHA is a great match for transoms designed for short-shaft outboards—portable in spirit, serious in capability. Ask us about warranty coverage available for this new Yamaha outboard and get rigged for your next season.
