2020 Yamaha Marine F90

The Yamaha 115 hp and the all-new 90 hp and 75 hp Midrange four strokes are reliable inshore performers. Fast and powerful, they sport 1.8-liter displacement and DOHC or SOHC designs with four valves per cylinder. This gives them exceptional volumetric efficiency and lighter weights. With 25-inch shaft options for the F115 and F90, this horsepower range offers prime power for mid-size craft, including anglers trolling large, rough water in 25-inch-transom multi-species boats. The completely surprising Yamaha Midrange 115, 90 and 75 hp four strokes. A powerful part of our lineup—and your boating experience.

The all-new 1.8-liter I-4 F90 features greater displacement and a single-overhead-camshaft design with four valves per cylinder. This boosts power and volumetric efficiency and streamlines design. In fact, it’s 13 pounds lighter than previous designs. A lighter, more powerful design gives the F90 blistering speed that’s 1.5 mph faster than competing outboards.
