Yamaha Announces New 4.2-liter F300 V6 Offshore “Mechanical” Outboard

Yamaha’s popular F300 now comes with mechanical control, offers perfect repower solution for larger craft

 Kennesaw, Ga., June 22, 2017 – Yamaha Marine Group announced today a new mechanical control version of its 300-horsepower 4.2-liter V6 Offshore outboard, available in both left and right-hand rotation.

“Yamaha Marine is dedicated to providing premium boating experiences for all of our customers, and we believe it’s important to incorporate a variety of choices throughout our product line to meet specific boat applications and customer demands,” said Ben Speciale, Yamaha Marine Group President.  “With this new model, customers now have the choice of mechanical or digital control for the F150, F175, F200, F225, F250 and F300 models.”

Whether you choose digital electronic control or the new mechanical control F300 you get the same features, power, and performance inside. 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 these outboards up to 17 percent more fuel efficient. With no need to carry two-stroke oil, the available space in the boat can be used more efficiently. 

V6 Offshore Mechanicals are 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 work boats or other craft where digital control is not needed or desired. 

Repower customers have a wide array of super quiet Yamaha SDS™ propellers to choose from, including the Saltwater Series II™ with SDS and the Saltwater Series HS4 with SDS. Yamaha’s patented Shift Dampener System distributes and absorbs the forces and the resulting sounds and vibrations that are normally associated with shifting an outboard into gear. 

Expected availability of Yamaha’s new 4.2-liter F300 V6 Mechanical model is summer 2017.
