Yamaha F20 Owners Manual
Yamaha’s high-powered portables are redefining the expectations for portable horsepower, from the F15 and F20 to the outstanding, new F25, an IBEX Innovation Award Winner for 2017. 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 four-stroke 25 hp, previously a midrange outboard, is now so light, it’s jumped to our portable family. Like its new F15 and F20 siblings, the F25 has taken on signature portable advantages like an oil-retention system for leak-free, on-side storage capability, carry handles and resting pads.
So whether you’re headed duck hunting with a jon boat or on the way to a lake cottage and your 14-foot aluminum boat, your Yamaha portable’s ready to go. Convenience & Control Max Maneuverability A 45-degree steering angle in each direction means great maneuvering potential. 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. Portable 25 hp Our 432-cc 25-hp portable outboard sports a new, streamlined, portable design and class-leading power-to-weight. In fact, it’s 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. Available for remote mechanical or tiller-handle control.
