4.2 Liter Big-Bore Displacement Class-leading 4.2-liter displacement

4.2 Liter Big-Bore Displacement

By using a highly advanced thermally applied plasma fusion process on the cylinder walls, Yamaha’s new line of V6 Offshore outboards have no conventional steel cylinder sleeves, yet the cylinder walls are 60% 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.

Lightest Weight in Class Up to 73 lbs. lighter than competitors

Lightest Weight in Class

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. There’s even a new advanced polymer composite lower engine pan that lowers weight and increases corrosion resistance.

Throttle Response and Acceleration Variable Camshaft Timing increases torque

Throttle Response and 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 new 4.2 liter big-bore V6 Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.

Best-in-Class Fuel Efficiency 17% better long-range fuel economy

Best-in-Class Fuel Efficiency

Yamaha’s 300hp V6 Offshore outboard has up to 17% better long-range fuel economy at 3500 rpm than other 300hp 4 stroke outboards. All air entering the engine block of each Yamaha V6 Offshore outboard is routed through a single 75mm electronically controlled throttle valve. Working in concert with the Precision Multi-Point Fuel Injection System, together they help ensure the precise amount of air and fuel necessary for optimum power and fuel efficiency. The reduction in friction from the Micro-Textured Cylinder Walls further adds to this outboard’s amazing fuel economy.

Best-in-Class Charging Power 29% high alternator power

Best-in-Class Charging Power

With 70 amps of total alternator output, Yamaha’s new V6 Offshore outboards have over 29% higher total alternator power than other V6 four stroke outboards. That kind of charging power is vital to help operate today’s wide array of on-board electronic devices.

More Information / Security Command Link Plus and Y-COP Anti-Theft System

More Information / Security

Featuring a new 5” high-contrast, multi-engine, LCD display; new Command Link Plus® Digital Electronic Controls; new key switches and start/stop panels; and new Command Link Plus accessories, this system offers more convenience, flexibility, and information than ever before. There’s even the optional new Y-COP™ Immobilizer system, which allows the operator to disable the outboard’s ignition system using a battery-operated key fob during periods of non-use, thus helping to deter theft.

Protection from the Elements Cowling drain system

Protection from the Elements

All Yamaha V6 Offshore outboards feature a proven cowling drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that trap and drain water before it enters the engine’s intake, for maximum reliability.

Reliability and Efficiency Four valves per cylinder for efficiency

Reliability and Efficiency

4.2 liters of class-leading displacement teams with individual intake and exhaust camshafts to provide more precise valve timing control with fewer moving parts than conventional rocker arm systems for increased reliability. This superior design also allows for use of 4 valves per cylinder which exchange intake and exhaust gases more efficiently for responsive power and increased fuel economy.

Advanced Technology Six sensors for combustion efficiency

Advanced Technology

Six individual sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which instantly makes the precise adjustments for optimum performance and efficiency.

Cruising Speed Up to 19% faster at cruise RPM

Advanced Technology

The Yamaha F300 is up to 19% faster at cruise rpm than other 300hp four stroke outboards. Cruise rpm is where most offshore outboards are typically operated, meaning you get there faster, using less fuel, than competitive models.

Smooth Shifting Shift dampening system

Smooth Shifting

Yamaha's patented Shift Dampener System (SDS™) greatly reduces noise commonly associated with shifting gears. Using a special new design and components, much of the resulting force is absorbed, resulting in far quieter and smooth operation. Currently available on Saltwater Series II™- SDS™ three-bladed propellers and Saltwater Series HS4 SDS four-bladed propellers. Both styles are ideal for V6 Offshore outboards and their typical applications. SWS II propellers are available in 13", 15", 17", 19", 21" and 23" pitches, while SWS HS4 propellers are available in 21”, 22” and 23” pitches.

Increased Cooling Capacity Variable Trolling RPM Control

Increased Cooling Capacity

Yamaha V6 Offshore models come standard with dual pairs of water inlets, for increased cooling efficiency. Located on the front and both sides of the lower unit, each pair of pick-ups operates independently of each other to provide proper water flow in a wide variety of applications and conditions.

Precise and Convenient Trolling Variable Trolling RPM

Precise and Convenient Trolling

Controlled by a Command Link® Plus digital display or a Command Link tachometer, our Variable Trolling RPM Control allows the operator to adjust the engine’s trolling speed from 600 ~ 1000 RPM, in 50-RPM increments. This helps provide precise and consistent trolling speeds in a wide array of conditions.

Vibration Reduction Re-engineered long span mounting system

Vibration Reduction

Yamaha V6 Offshore Outboards utilize a new version of our Long Span Mounting System, which employs a specially formulated rubber compound attached to newly designed engine mounts. Placed as far apart vertically and horizontally as practically possible, they provide necessary strength while minimizing vibration.
