Yamaha 90HP – 20″ VMAX SHO, 2022 In-Line 4

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.
