A tangerine sunrise alights the shore as you load up the gear for a morning of coastal fishing. Your buddies are rearing to go—as are your twin V6 Offshore outboards. Known for their power, efficiency and outstanding 96 percent reliability,** Yamaha’s V6 4.2-liter outboards are some of the most trusted V6’s on the water. Now, they’re also some of the nimblest, with integrated digital electric steering. This makes them more responsive than ever. Our V6 Offshore outboards have proven once again that even a trusted favorite can take an exciting turn.

Perfect for 20-foot decks or deep-Vs, the versatile V6 4.2-liter F225 allows you to increase your displacement without replacing your rigging.

Features may include:
  • Recommended fuel: 87 Octane
  • Shaft length: 25”
  • Alternator output: 50 amp

Power and 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.

Convenience and Control

Precise and Convenient Trolling

Speed Control with Pattern Shift automatically bumps engines into and out of gear to achieve sub-idle trolling speeds. Helm Master EX with Autopilot even allows you to set a target speed as low as 0.25 mph. This cues the system to auto-adjust RPM and shifting to achieve that target speed—all while adjusting for conditions such as wind or current. This provides incredible control of trolling speed—from in-gear idling to slowing to a crawl.

More Functionality / Security

Helm Master EX includes Autopilot with Heading/Course Hold, 10+ automated modes for fishing and relaxing, in-mode joystick adjustability and the expanded ability to control up to five outboards. There’s even an optional theft-deterrent system, Y-COP®, which disables the ignition and fuel systems while docked.

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.
