Power and Performance.

• Quiet Power and Performance: Yamaha 150HP – 20″ V MAX In-Line 4 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: Yamaha 150HP – 20″ V MAX In-Line 4 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: Yamaha 150HP – 20″ V MAX In-Line 4 has 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.

• Unbeatable Reliability: Yamaha 150HP – 20″ V MAX In-Line 4 feature a Cowling Drain System and Air Intake Labyrinth System to trap and drain water that enters their cowlings during normal operation.
• Better Lubrication: Yamaha 150HP – 20″ V MAX In-Line 4 has a 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.
