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.
Our 1.8-liter I-4 F115 is the lightest DOHC 115-hp In-Line Four on the water by nearly 25 pounds, leading its class in power-to-weight. It not only bests the competition, but it also beats Yamaha’s previous F115 design, with a zero-to-200-foot acceleration time that’s 0.7 seconds faster.
