PORTABLE 25 hp

Our 432-cc 25-hp portable outboard sports a new, streamlined, portable design and class-leading power-to-weight. In fact, its the lightest 25-hp outboard on the water—two-stroke or four-stroke. While its streamlined design is 25 percent lighter, it still packs exciting features like battery-less EFI. Pull-start models can now take advantage of this feature, plus the system is designed with an automatic decompression device to require even less effort for manual starting.

EASY ENGINE FLUSHING

A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.

 

PORTABILITY AND STORAGE

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.

 

 

RELIABILITY & DURABILITY

OPTIMAL OPERATION

CDI Microcomputer Ignition monitors throttle position, engine speed and atmospheric conditions in order to precisely adjust ignition timing under all conditions for optimum ignition performance, ensuring smooth and reliable operation.

 

EFFICIENT POWER

The F25, F20 and F15 all feature a two-valve-per-cylinder, single-overhead-camshaft design that provides better breathing and more power.

 

OPTIMUM PERFORMANCE

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

 

RESPONSIVE ACCELERATION

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.

 

THE NEW, 25 HP PORTABLE

Yamahas F25 has gone through a redesign so transformative, its now the lightest 25-horsepower outboard on the water—two stroke or four stroke. Its new portable design and class-leading power-to-weight mean 25 horses can boldly go where theyve never gone before. Jons. 14-foot aluminum fishing boats. The bed of your truck.PORTABLE 25 hp
