2025 Yamaha Outboards F4 hp

The harbor is like glass as you board the tender to your cuddy for a day on the water; your trusty Yamaha Portable ushering you out. With easy starts, incredible efficiency and reliable performance, Yamaha’s F6, F4 and F2.5, are perfect for all sorts of light duty. Wherever the day takes you, take along a little extra power with Yamaha’s smallest Portables.

Our 139-cc 4-hp portable outboard mirrors our OHV F6, with a couple less horses. It features the same ergonomic, easy-grip starter handle with a built-in decompression device for effortless starts. The F4 also features a built-in fuel tank with the option of switchable access to an additional external tank for amazing extended range. There’s no stopping this little brute.

Features may include:
  • Only 60 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths
  • Solid 6-amp alternator

Power and Performance

Lightweight, Portable Power

They may weigh as little as 37 pounds, but these Overhead-Valve portable outboards are packed with features that create smooth, quiet power. This includes a CDI or TCI ignition system, an optimally balanced crankshaft, a long span mounting system and a labyrinth exhaust.

Surprising Performance

The portable F6, F4 and F2.5 all offer impressive features like electronic ignition, thermostatic cooling and 180-degree steering.

Record Setting Fuel Efficiency

Small motors use less fuel, but according to the Guinness Book of World Records, the Yamaha F4 actually set a world record for fuel efficiency, traveling 67.27 continuous statute miles on one gallon of gas.

Convenience and Control

EASY STORAGE

Yamaha’s F2.5, F4, and F6 feature our Easy Storage Oil Retention System. This pressurized oiling system prevents leaks, enabling on-side storage.

COMFORTABLE CONTROL

Incredibly nimble, the F6 and F4 feature 180-degree steering and the F2.5 features 360-degree steering with a dynamically balanced and dampened twist-grip throttle for comfort and convenient maneuverabilty.

PORTABILITY AND STORAGE

Built-in front and rear handles make these lightweights easy to carry. Resting pads and an easy oil retention system allow for convenient on-side storage without cowling scuffs or oil leakage.
