Meet the Lineup
6 HP
Our 139-cc 6-hp portable is an impressive little outboard. It boasts surprising features for such a small motor, like labyrinth exhaust and a long span mounting system for smooth, quiet power. It also offers the convenience of an external fuel tank (in addition to its built-in tank) for extended range and added convenience.
- Only 60 pounds (15” shaft model)
- Available in 15” and 20” shaft lengths
- Solid 6-amp alternator (optional)
4 HP
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.
- Only 60 pounds (15” shaft model)
- Available in 15” and 20” shaft lengths
- Solid 6-amp alternator
2.5 HP
Our 72-cc 2.5-hp portable outboard is the smallest motor on our roster, but it still packs a punch. Completely redesigned, it’s even more portable, easier to store and clean burning.
- Only 37 pounds (15” shaft model)
- Available in 15” and 20” shaft lengths

PORTABLES PACKED WITH
PERFORMANCE
They weigh as little as 37 pounds, but all offer impressive features like electronic ignition, thermostatic cooling and 180-degree steering.
Features & Benefits
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.
The portable F6, F4 and F2.5 all offer impressive features like electronic ignition, thermostatic cooling and 180-degree steering.
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.
Yamaha’s F2.5, F4, and F6 feature our Easy Storage Oil Retention System. This pressurized oiling system prevents leaks, enabling on-side storage.
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.
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.
RELIABILITY & DURABILITY
WET SUMP
A pressurized oil delivery system that incorporates a compact and durable oil pump to keep all of the moving parts of their Overhead Valve systems lubricated and running smoothly for maximum reliability.
