The new mechanical control F300 offers the same features, power and performance as the digital version. Yamaha’s 4.2-liter offshore models have big-bore V6 displacement thanks to plasma-fused sleeveless cylinders. This technology increases displacement without enlarging the outer diameter of the cylinder bores, resulting in an outboard with the largest displacement in its class. The technology also contributes to the outboards’ light weight.
An electronically controlled single throttle valve and Precision Multi-Point Electronic Fuel Injection make the outboards up to 17% more fuel-efficient.
V6 Offshore Mechanicals are also more than 50 pounds lighter than the venerable Yamaha 3.3-liter V6s. In addition, they offer better low- and mid-range punch and better fuel efficiency.
When repowering with the Yamaha 4.2-liter V6 Mechanicals, there is typically no need to change over to a new control box, thus providing an economical solution for workboats or other craft where digital control is not needed or desired.
