- Yamaha’s award-winning V6 4.2-liter outboards have been offshore favorites for more than a decade. Initially, boaters were attracted to their power, efficiency and intelligent design. After years of proven performance, our V6 4.2-liters have become known for something perhaps even more valuable offshore—reliability. In fact, with legendary 97 percent reliability,** they’re one of the most trusted V6’s offshore. Well, now these trusty outboards are turning heads again, with a fresh new look and new, integrated digital electric steering—making them even more responsive. Our V6 Offshore outboards have proven once again that even a trusted favorite can take an exciting turn.
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.
CONVENIENCE & CONTROL Of 300 hp yamaha outboard
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.
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
Our digital V6 Offshore models are compatible with Helm Master® EX boat control system. Helm Master EX offers functionality including Autopilot with Heading/Course Hold, 10+ automated modes for fishing and relaxing, in-mode joystick adjustability, expanded automated essential boat operations and more. 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 new 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
A new, 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.
