HIGHLIGHTS

Lighter

From the top of the cowling to the tip of the propshaft, every ounce of weight savings has been realized for maximum performance without sacrificing durability. There's even an advanced polymer composite lower engine pan that lowers weight and increases corrosion resistance.

Quicker

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 4.2-litre big-bore V6 Offshore Outboard to deliver awesome holeshot and mid-range acceleration you have to feel to believe.

Smarter

Air enters the engine block and is routed through a single 75 mm electronically controlled throttle valve. This works in concert with the Precision Multi-Point Fuel Injection System to ensure the precise mixture of air and fuel for optimum power and fuel efficiency. The reduction in friction from the Micro-Textured Cylinder Walls further increases the amazing fuel economy!

KEY FEATURES

4.2-litre 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, better cooling, and "micro-textured" cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.

FEATURES AND BENEFITS

4.2-LITRE 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, better cooling, and "micro-textured" cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.

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-litre big-bore V-6 Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.

CRUISING SPEED

Yamaha V6 Offshore 4.2 Liter is up to 19% faster at cruise rpm than other competitive four-stroke outboards. Cruise rpm is where most offshore outboards are typically operated, meaning you get there faster, using less fuel, than competitive models.

PATENTED SHIFT DAMPER SYSTEM (SDS)

Yamaha's patented new 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. Initially available on Saltwater Series II - SDS propellers, which are ideal for these outboards and their typical applications.

PROTECTION FROM THE ELEMENTS

All Yamaha V-6 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.

PROTECTION AND POWER

Yamaha V-6 Offshore Outboards feature an exhaust pressure reduction system, which not only helps keep the propeller hub cooled from hot exhaust gases, it also helps provide more power by helping to force those gases out of the engine.

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 operate independently of each other to provide proper water flow in a wide variety of applications and conditions.

RELIABILITY AND EFFICIENCY

4.2 litres 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.

VIBRATION REDUCTION

Yamaha V-6 Offshore Outboards utilize a new version of our Long Span Mounting System, which employs a speciallyformulated 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.

SMOOTH AND QUIET

Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet, for unbelieveably smooth and quiet operation.

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.
