Yamaha F90

Yamaha’s new lightweight F90 4-stroke is equipped with a 4-cylinder, 16-valve in-line SOHC 1.8L engine, with bigger displacement than the previous generation 1.5L engine it replaces. The bigger F90 is nearly 10kg lighter than the old engine, resulting in improved performance and better balance when fitted on hulls in this category. The F90 is based on the F115B’s 4-cylinder power unit. The design allows the F90 to achieve the weight savings of a single camshaft while still achieving the smooth and efficient performance only seen in 16 valve, 4-cylinder engine of this size. The F90 delivers a 10% improvement in fuel economy, and it’s also very smooth and quiet. It shares the same installation mounting holes as other outboards of similar sizes, making for an easy switch from a two-stroke or other brands. It’s compatible with Yamaha’s command link digital gauges, and is also NMEA2000 compatible.
