F15SEHA Yamaha 4 Stroke 15hp Portable Outboard – Compact Power, Maximum Reliability

The F15SEHA Yamaha 4 Stroke 15hp Portable Outboard is the perfect blend of lightweight design, fuel-efficient power, and Yamaha’s proven four-stroke reliability. Compact yet powerful, it’s engineered for boaters who demand dependable performance for fishing, tender runs, and leisure cruising without sacrificing portability or economy.

This 15hp outboard is part of Yamaha’s acclaimed portable range — offering smooth acceleration, quiet operation, and advanced engineering ideal for small boats, inflatables, and aluminum fishing vessels. Whether you’re navigating inland waterways, powering a dinghy, or running a backup kicker motor offshore, the Yamaha F15SEHA delivers effortless control and responsive handling in every condition.

Engineering and Mechanical Design

At the core of the F15SEHA is a two-cylinder, 4-stroke, 362cc engine designed for easy starting and efficient performance. The engine’s Single Overhead Camshaft (SOHC) system improves combustion precision and fuel burn efficiency, while Yamaha’s Electronic Ignition (CDI) ensures instant, reliable starts — even after extended storage periods.

The manual start and tiller handle configuration give boaters direct, tactile control, while the short shaft (15″) design suits small transoms and portable use. Its Forward-Neutral-Reverse (F-N-R) gear system allows seamless shifting and precise maneuvering, particularly in tight marinas or when trolling.

Lightweight aluminum construction and an anti-corrosion coating extend the outboard’s life, even in harsh saltwater environments. Combined with Yamaha’s precision machining and tight tolerances, the result is a portable motor that runs smoothly with minimal vibration.

Performance and Benefits

The Yamaha F15SEHA offers performance well beyond its class. Delivering 15 horsepower with steady torque across all RPMs, this model makes planing effortless for small boats and provides consistent thrust for everyday boating tasks.

Key advantages include:

• Fuel Efficiency: 4-stroke technology and EFI-like precision ensure maximum mileage on every tank.

• Low Noise & Vibration: Engine mounts and muffler design reduce noise for a quieter ride.
