The all-new 2022 Yamaha 115HP – 20″ Shaft is Yamaha’s fastest 115-hp four stroke, with a top speed of nearly 51 mph. In addition to top speed, it features tech that is unheard of in other brands. Including a long-track intake system, free-flow exhaust and knock sensor. Furthermore, Its lightweight design combined with 1.8-litre displacement. This makes the  V MAX SHO the class leader in torque and top speed. In Addition to that the option of a 20-inch shaft is an exciting new prospect. Finally, 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: Yamaha 115HP – 20″ Shaft design maximizes combustion efficiency in a way that no two stroke can, delivering clean, quiet power and performance.
• Fuel Efficient: Yamaha 115HP – 20″ Shaft designs are up to 40% more fuel efficient than traditional carbureted two strokes.
• Optimum Power: 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: This system 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: Combined with our proprietary alloy (YDC-30), our exclusive Phaze 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 less weight and more storage room in the boat for tackle and gear.
• Easy Rigging: Yamaha 115HP – 20″ Shaft 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.

Model Specific Features

• 1.8-liter high-output four cylinder
• 377 lbs. dry weight
• 20-inch and 25-inch shaft options
• 35 amps of charging power
• Command Link® compatibility with Variable Trolling.
