New Yamaha F90 90HP 4 Stroke Long Shaft Outboard Engine – Sale !!

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.

The F90 is equipped with a four-cylinder 16-valve in-line SOHC 1.8L engine, bigger displacement than the previous generation 1.5L engine it replaces. Most impressively the bigger F90 weighs in close to 10kgs lighter than the old engine. This remarkable achievement means improved performance, and better balance when fitted on hulls in this category.

The F90 is based on the F115B’s four-cylinder power unit. The F90’s reduction in weight and improved compactness is achieved by adopting a single overhead camshaft design (SOHC), actuating four valves per cylinder. This unique valve train design was first seen in Yamaha’s award-winning F70A, one of the most popular engines in Australia. This 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, four-cylinder engine of this size.

This lightweight powerhead configuration, refined shaping of the combustion chamber and lean fuel burn technology utilised at mid-range speeds, allows the F90 to deliver exceptional fuel efficiency.

The new F90 delivers a 10% improvement in fuel economy compared with the previous generation engine. The F90 is not only extremely fuel efficient it’s also exceptionally smooth and quiet. Noise has been reduced through improved engine unit rigidity, muffler redesign as well as addition of an intake silencer.
The F90 is compatible with Yamaha’s comprehensive range of command link digital gauges, with options of both basic back-lit LCD and premium full colour displays. The engine is also NMEA2000 compatible allowing the F90 to share information with third party multi-function displays, GPS and fish finders.

The amount of engine development and innovation that can be found in Yamaha’s mid-range outboards is truly unique, and the new F90 strengthens Yamaha’s product offering across this range. Yamaha has not resorted to a “one size fits all” style engine platform to minimize production costs. Not only does Yamaha have a class leading outboard motor in each horsepower category, Yamaha also produces the most diverse range of engine platforms within these horsepower categories. This reflects Yamaha’s focus on delivering customer driven innovation to the marine marketplace. Each engine platform has been tailor-made to satisfy the individual requirements of customers and their boats. Within Yamaha’s range, there is no need for Australian skippers to compromise when it comes to selecting a power option.

The all-new F90 neatly shares the same installation mounting holes as other outboards of similar sizes, making for an easy switch from a two-stroke, or other brands to the latest generation Yamaha four-stroke engine.
