High-Power Portable

Yamaha’s high-powered portables are redefining the expectations for portable horsepower, from the F15 all the way to the NMMA® Innovation Award-winning F25. Their single-overhead-camshaft, two-cylinder designs create power to weight that’s not only eye-opening—but in the case of the F25, it’s also class-leading and category jumping. In fact, the Yamaha’s 25 hp is the lightest 25 on the water—two stroke or four stroke. Like its F15 and F20 siblings, the F25 has signature portable advantages like carry handles, an oil-retention system for leak-free, on-side storage and more. Now, the F25 is also available in new pearlescent white and matte brown.* So, whether you’re duck hunting with a jon boat or headed to a lake cottage with your 14-foot aluminum boat, your Yamaha portable’s ready to go. *New color options available in select models and subject to availability.
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.
