For a big horsepower offshore engine that is going to get you there and back quickly and safely, the F300 represents the pinnacle in Yamaha’s latest generation V6 outboard range.

This engine is not only powerful, but lightweight, due to its innovative plasma-fused sleeveless cylinders, which not only reduces weight but provides an increased engine capacity for improved power and performance.
