Yamaha’s high-powered portables are redefining the expectations for portable horsepower, from the F15 to the all-new F20 built on the same outstanding platform as the F25, a 2017 IBEX Innovation Award Winner. 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 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
