PORTABLES
The marsh rustles in the fall breeze as you deploy your decoys. There’s nothing like a trusty Yamaha Portable outboard for a crisp day of fishing or duck hunting. Yamaha’s Portable F25, F20 and F15 pack impressive power-to-weights and all the advantages of Yamaha’s award-winning, portable design, including carrying handles, incredibly light weights and more. The F25 even comes in matte brown, in case stealthy is part of the ask. No matter what’s ahead, your Yamaha Portable will be ready to go.

THE OUTSTANDING,
25 HP PORTABLE
Yamaha’s F25 is still the lightest 25-horsepower outboard on the water—two stroke or four stroke. Its portable design and class-leading power-to-weight mean 25 horses can boldly go where they’ve never gone before. Jons. 14-foot aluminum fishing boats. The bed of your truck.
Features & Benefits
The F25, F20 and F15 all feature a two-valve-per-cylinder, single-overhead-camshaft design that provides better breathing and more power.
An optimally balanced crankshaft and labyrinth exhaust deliver smooth power, while Microcomputer Ignition adjusts timing to maintain maximum engine performance, economy and power under all conditions.
An intake silencer and manifold on the F20 and F15 result in more direct airflow, for minimum noise and maximum power.
An acceleration pump on the F20 and F15 gives the engine the fuel it needs--when it needs it--like during rapid throttle advance. This ensures responsive acceleration
A 45-degree steering angle in each direction means great maneuvering potential.
A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
Incredible light weights, built-in resting pads and carry handles, an easy oil retention system and an optional folding tiller handle, allow for easy carrying and on-side storage without oil leakage or cowling scuffs.
