2023 Yamaha Vmax 90 SHO 20
2023 Yamaha Vmax 90 SHO 20
2023 Yamaha Vmax 90 SHO 20, The All-New VF90 In-Line Four V MAX SHO. A single-overhead-camshaft design with four valves per cylinder and 1.8-liter displacement make the I-4 V MAX SHO 90 a class leader in torque, top speed and efficiency. Even still, it’s one of the quietest 90-horsepower outboards on the water. That makes for some pretty stealthy fishing.
Available for mechanical remote or tiller control.
POWER & 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.
- Midrange Power and Response: The V MAX SHO® 175 and 150 feature Variable Camshaft Timing, which optimizes the angle of the intake camshaft to increase power and throttle response in the low- and mid-RPM ranges.
- Fuel Efficient: In-line Four V MAX SHO® 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 & DURABILITY
- Unbeatable Reliability: The I-4 V MAX SHO® 175 and 150 feature a Cowling Drain System and Air Intake Labyrinth System to trap and drain water that enters their cowlings during normal operation.
- 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 & 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.
- Ample Charging Power: With 50 amps for the I-4 V MAX SHO 175 and 150, and 35 amps for the 115 and 90, their alternators produce enough power for battery charging and a range of on-board electronics.
- 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.
