2024 Yamaha Marine V6 4.2L 250 HP

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.

Our V6 4.2-liter F250 is perfect for offshore dual or center consoles, walkarounds, runabouts and pontoons. It allows you to step up your horsepower and displacement without rerigging. Only now, it features a fresh, new cowling design (with engine-mounted Propeller Indicator Lights) if rigged with Helm Master® EX), new integrated digital electric steering* and rerouted exhaust for enhanced reverse thrust. It just proves even the best can get even better.

• Recommended fuel: 87 Octane

• Shaft lengths available: 25”, 30”, and 35" (30" and 35" on F250 DEC only)

• Alternator output: Up to 70 amp

• 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.

• 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.

• 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

• 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.

• 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.

• 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.

• A 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.
