• 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.

• 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.

• 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: At 50 amps, the V MAX SHO 175 and 150 alternators boast an 11 percent increase in charging power over the two stroke 150 HPDI.
• 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.

• The I-4 V MAX SHO 115 is Yamaha’s fastest 115-hp four stroke, ever, with a top speed of nearly 51 mph.* On top of its impressive speed, it features tech unheard of in its class, including a long-track intake system, free-flow exhaust and knock sensor. Still it’s 10 pounds lighter than a competitor’s two stroke. (*Tests conducted by Yamaha Marine using a Skeeter TZX170 with a tournament load and two occupants.)
• 1.8-liter high-output four cylinder
• 377 lbs. dry weight
• 20-inch and 25-inch shaft options
