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.

Fuel Efficiency

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.

Light Weight

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.

Throttle Response & 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 outboards deliver awesome hole shot and mid-range acceleration.
