Yamaha announces 4.2-liter F300 V6 offshore “mechanical” outboard

Yamaha Marine Group announced 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.”

With both the digital electronic control or the new mechanical control F300, customers will 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. The company says this technology increases displacement without enlarging the outer diameter of the cylinder bores. The technology also contributes to the outboard’s 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, the company says 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.

Yamaha said repower customers have an array of 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 is diesnged to distribute and absorb 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.
