Yamaha VF90 I-4 1.8L V MAX SHO Mechanical 20

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.
• 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.

Features

• STREAMLINED POWER, EXTENDED: All In-Line Four V MAX SHO® outboards are now available with 25-inch shafts. This brings V MAX SHO performance to multi-species boats, bay boats, pontoons and other 25-inch transom applications.
• PROP SHAFT HORSEPOWER: 90 hp at 5,500 rpm
• COMPRESSION RATIO: 10.0:1
• RECOMMENDED FUEL: Octane 87
• C.A.R.B. RATING: 3-Star
• INTAKE: 16
• SPARK PLUG: LFR5A-11
• ETHANOL BLEND LIMIT: 10% maximum
• Compatible with Mechanical Controls

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.
• 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

• 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.
