2025 Yamaha Outboards F25 Portable F25SMHC
Yamaha’s F25 is so light, powerful, and feature-rich that it won a coveted NMMA® Innovation Award shortly after introduction. As the lightest 25 horsepower outboard available—two-stroke or four-stroke—it features the highest power to weight ratio in its class and comes in several variations to suit your needs. From power trim and tilt, tiller or remote control, 15 or 20-inch shaft and now in pearlescent white or traditional grey!
