Features

Convenience & Control

  • CHARGING POWER: Our V6 4.2-liter outboards feature up to 70 amps of total alternator output—ample charging for an array of on-board electronic devices.
  • TOP SPEED AND SMOOTH SHIFTING: Our Saltwater Series II™ HP Propeller can boost top-end speed up by nearly 2 mph in lighter-weight applications. It’s also equipped with our patented Shift Dampener System (SDS™) for smoother, quieter shifting.
  • FAST, EASY TILTING: Yamaha exclusive, TotalTilt™ performs a quick, full trim up or down with the fast, double-tap of a button. This makes trailering quick and easy and is handy when a complete up or down tilt is needed.
  • POWERFUL, PRECISE MANEUVERING: Thrust Enhancing Reverse Exhaust keeps exhaust bubbles away from the propeller below 2500 RPM and when in reverse. This means the prop bites only clean water, which results in outstanding reverse thrust and control—especially when backing down on fish and when maneuvering around docks.

Features

  • PROP SHAFT HORSEPOWER: 225 hp at 5,500 rpm
  • COMPRESSION RATIO: 10.3:1
  • RECOMMENDED FUEL: Octane 89
  • RECOMMENDED FUEL FILTRATION: Yamaha 10-micron fuel / Water separating filter (external)
  • C.A.R.B. RATING: 3-Star
  • INTAKE: 24
  • SPARK PLUG: LFR6A-11
  • MOUNTING CENTERS: 28.5 in.
  • Compatible with Mechanical Controls
  • Compatible with Command Link® and Analog Gauges

Power & Performance

  • 4.2 LITER BIG BORE DISPLACEMENT: Yamaha’s 4.2-liter V6 Offshore outboards feature plasma-fused sleeveless cylinder walls, which are 60 percent harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight and better cooling, and “micro-textured” cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.
  • FUEL EFFICIENCY: For maximum power and efficiency, electronically controlled throttle valves work in concert with Precision Multi-Point Fuel Injection to ensure a precise mix of air and fuel. In addition, six individual sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which makes adjustments for performance.
  • LIGHT WEIGHT: From the top of the cowling to the tip of the propeller shaft, every ounce of weight-savings has been realized for maximum performance without sacrificing durability.
  • THROTTLE RESPONSE & ACCELERATION: Yamaha’s Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-RPM ranges. This feature helps Yamaha’s 4.2-liter big-bore V6 outboards deliver awesome hole shot and mid-range acceleration.

Reliability & Durability

  • HOLE SHOT & ACCELERATION: Variable Camshaft Timing (VCT) boosts power and throttle response in the low- and mid-RPM ranges.
  • LONG RANGE FUEL ECONOMY: Multi-Point Electronic Fuel Injection ensures a precise mix of air and fuel for combustion efficiency.
  • MORE POWER: Plasma-fused cylinders result in larger cylinder bores for greater displacement, power, torque and reduced weight.
