The F25 delivers the weight and performance you would expect from a two-stroke, with all of the advantages that comes with Yamaha’s industry-leading four-stroke technologies. This new generation outboard is not only an improvement on the four-stroke model it replaced, but also exceeds the all-round capabilities of Yamaha’s legendry 25 two-stroke outboard.

For the first-time in Yamaha’s four-stroke history, the F25 comes with a battery-less fuel injection option – delivering easier starts, better fuel economy and an improved overall operating performance.

Yamaha’s F25 delivers the industry’s highest power-to-weight ratio and options to suite every boating style. Choose from mechanical and/or electric start, mechanical tilt or power, trim and tilt (PTT), and a redesigned tiller handle or forward control options – now in both short and long shaft models.

With all the features and options normally only seen in Yamaha’s bigger horsepower models, the F25 punches well above its weight.
