A few years back, Yamaha completely turned four-stroke engine design on its head by introducing the ground-breaking F225H. Weighing in at just 10% more than two-strokes of the same class, these motors mounted beautifully on boats designed for that HP rating.

And now Yamaha's innovation continues with the F250H, one of the most advanced fuel-injected models ever. On all our large four-strokes, you expect light weight, compactness and masses of power, and those pure Yamaha characteristics are exactly what you get.
