Yamaha F90


Yamaha F90

Perfectly Matched

The new generation F90 delivers the perfect combination of increased power, reduced weight and improved performance.

Filling an important place in Yamahas class leading mid-range line-up, the new F90 delivers the perfect power option for the large number of Aussie built boats that have a maximum hull rating of 90 horsepower.

The four-cylinder, 16-valve, in-line SOHC 1.8L engine, is not only 10kgs lighter, but delivers a bigger displacement than the previous generation 1.5L engine it replaces.

The reduction in weight and improved compactness has been achieved through the adoption of a single overhead camshaft design, delivering a smooth and efficient performance only seen in 16 valve, four-cylinder engines of this size.

The new F90 delivers a 10% improvement in fuel efficiency and a significant reduction in noise, through improved engine unit rigidity, muffler redesign and the addition of an intake silencer.

This F90 is compatible with Yamaha’s range of command link gauges, while its NMEA2000 compatibility allows easy integration with third party multi-function displays, GPS and fish finders.
