Overview
Nothing beats a day on the water with family and friends. And nothing powers those moments quite like Yamaha's versatile line of midrange outboards. Ranging in size from the mighty F90 down to the nimble F25, they offer just the right amount of power for a variety of applications. These 2-, 3- and 4-cylinder dynamos are quiet, clean-burning, reliable performers. But that's not all they have to offer.
