Yamaha F90CETL




The next-generation F90 is a direct-evolution of the previous 1.5 litre model, delivering increased
fuel-efficiency, reduced-weight and improved performance. Filling an important place in
Yamaha’s 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, SOHC 1.8L marine engine, is not only 10KGs lighter, but an increase in
displacement over the previous generation 1.5L engine aids in a richer torque-band.
The reduction in weight and improved compactness has been achieved through the adoption of a
single overhead camshaft valve-train, delivers 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.
