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, streamlines design, and makes the F90 a leader in torque and acceleration. The new F90 fills an important place within the Australian line up, delivering the perfect power option for the huge number of Aussie built boats rated to a maximum of 90 horsepower. Not only does this engine sit in a popular part of the market, it also delivers many new advantages that make F90 quite exceptional.

When you need to get to where a prop won't take you, get an F90 Jet Drive. This 65hp engine is a marine-inspired 4-stroke that's as much as 50% quieter than a conventional 2-stroke, and up to 30% more fuel efficient, too. Yamaha's completely redesigned, 1.8-liter F90 Jet Drive four stroke produces 65hp at the pump. Its compact, light-weight SOHC four-cylinder, in-line design features a long-track induction system and Yamaha’s proprietary YDC-30 aluminum alloy. This creates a light, compact, powerful outboard for deck boats and deep-V hulls navigating shallow, rocky rivers.
