When embarking on a morning of coastal fishing or an offshore adventure, reliability and performance are non-negotiable. The Yamaha V6 Offshore outboards have long set the standard for power in marine propulsion. Our featured Yamaha V6 4.2L 300 HP outboard combines legendary dependability with modern technological enhancements, ensuring you spend more time fishing and less time worrying about your equipment.
Exceptional Power from a Reliable 4.2 Liter V6 Engine
The core of this powerful unit is the robust 4.2-liter V6 engine displacement. Yamaha engineers have designed these engines for peak performance, utilizing advanced technology to maximize power output while maintaining fuel efficiency. Key features include plasma-fused sleeveless cylinder walls—which are significantly harder than steel—allowing for larger bore sizes and increased torque without increasing weight or outer dimensions. This design focus results in a powerful yet remarkably light motor.
Advanced Performance Features
- High Efficiency Operation: For optimal power delivery, the engine integrates electronically controlled throttle valves with Precision Multi-Point Fuel Injection (EFI). Six individual sensors constantly monitor atmospheric and operational conditions, allowing the Engine Control Module to make real-time adjustments for peak performance.
- Lightweight Construction: Every component has been optimized for weight savings from top cowling to propeller shaft tip. This commitment to lightweight design boosts overall efficiency without ever compromising the durability required by offshore use.
Modern Convenience and Digital Control
The modern Yamaha V6 300 HP outboard is more than just raw power; it offers unparalleled control through integrated digital electric steering. This advanced system provides superior responsiveness, making the boat feel nimbler and easier to handle in various conditions.
Unmatched Control for Fishing
Whether you are trolling slowly or accelerating across open water, this motor adapts to your needs:
- Precise Trolling Speed: The system offers automatic speed control with Pattern Shift capabilities. When paired with systems like Helm Master EX Autopilot, users can set a target speed as low as 0.25 mph. This allows incredible positional holding and slow-speed maneuverability critical for effective fishing.
- Safety and Functionality: The advanced electronics suite includes Heading/Course Hold functionality and optional theft deterrence systems (Y-COP®), adding layers of security whether the boat is in use or docked overnight.
Key Specifications Overview
The 2026 model year Yamaha V6 offshore outboard continues to refine its performance profile, making it a top choice for serious anglers and recreational users alike.

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. 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 F300 is a reliable, offshore favorite—and it's only getting better. It now features a fresh, new cowling design (with engine-mounted Propeller Indicator Lights if rigged with Helm Master® EX), new integrated digital electric steering*, rerouted exhaust for enhanced reverse thrust and is available in Yamaha gray or pearlescent white. It’s destined to be a top choice offshore for years to come.
Features may include:
Recommended fuel: 89 Octane
Shaft lengths available: 25”, 30” and 35” (30" and 35” on F300 DEC only)
Alternator output: up to 70 ampPower and Performance
4.2 Liter Big Bore DisplacementYamaha’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 EfficiencyFor 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 WeightFrom 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 TrollingSpeed 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 / SecurityHelm 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 ShiftingOur 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.
