Their class-leading, 4.2L big-bore design means they have the best time-to-plane in their class. When cruising at 4000 RPM, the F300’s speed is up to 19% faster than other 300hp competitors.
Class-Leading Displacement
This next generation of V6 Offshore outboards features the first-ever marine application of plasma-fused sleeveless cylinders. This allowed engineers to increase the displacement to a class-leading 4.2 liters, without enlarging the outer diameter of the cylinder, keeping the motor light. The result is an outboard that is not only the lightest in its class, but that also has the largest displacement. No wonder it’s 19% faster than many other 300hp competitors.
Groundbreaking Fuel Economy
These V6s feature up to 17% better long-range fuel economy at 3500 RPM than comparable 300hp four strokes, thanks in part to a single, electronically controlled throttle valve, precision multi-point fuel injection and micro-textured cylinder walls.
17% more fuel efficient
Light Weight / Industry-First Technology
Through incredible innovations like plasma-fused sleeveless cylinders, Yamaha engineers have managed to shave every possible ounce from these outboards, without sacrificing a shred of durability or reliability. As a result, they’re up to 73 pounds lighter than other V6 outboards in their class.
Intuitive Control
Available with the Helm Master® fully integrated boat control system in twin-, triple and quad-outboard configurations.
