Description
The all-new 2022 Yamaha 90HP – 20″ Shaft may be the smallest in the V MAX SHO lineup, but it is also packed with a big punch. Its lightweight design combined with 1.8-litre displacement. This makes the VF90 V MAX SHO the class leader in torque and top speed. In Addition to that the option of a 25-inch shaft and the VF90 is an exciting new prospect. Furthermore, it supports mechanical, remote or tiller control.
POWER AND EFFICIENCY – Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamaha’s EFI optimizes fuel atomization further enhancing fuel economy.
Power and Performance.
Quiet Power and Performance: The I-4 V MAX SHO® design maximizes combustion efficiency in a way that no two stroke can, delivering clean, quiet power and performance.
Fuel Efficient: In-line Four V MAX SHO® designs are up to 40% more fuel efficient than traditional carbureted two strokes.
Optimum Power: Yamaha 90HP – 20″ comes with Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Four V MAX SHO® outboards.
Power Management: An array of advanced sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which instantly makes the precise adjustments for optimum performance.
Reliability and Durability.
Better Lubrication: Wet sump pump lubrication that uses a pressurized oil delivery system through an oil pump.
Engine Warning System: Yamaha 90HP – 20″ has a warning system that protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, water-in-fuel detection, start-in-gear protection and shift-in prevention at open throttle.
Corrosion Protection: Yamaha 90HP – 20″ is Combined with our proprietary alloy (YDC-30), our exclusive Phase Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha I-4 V MAX SHO® four-stroke engines.
Convenience and Control.
Extra Space: A four stroke in-line design means there’s no need for an external oil tank. That means Yamaha 90HP – 20″ weighs less and more storage room in the boat for tackle and gear.
Easy Rigging: I-4 V MAX SHO® outboards feature mechanical controls for easy, convenient rigging with most bass, bay and flats boats, and are compatible with analog, 6Y5 digital or Command Link® gauges.
