F300USB DES (Digital Electric Steering)

F300USB DES (Digital Electric Steering)

Next generation features, next generation styling, original reliability.

Yamaha’s all-new, V6 Offshore series takes the proven 4.2 litre engine platform to the next level by incorporating technological advancements previously only seen on Yamaha’s flagship V8 425hp XTO.

The new F300 not only looks good with it's more aggressive styling, but comes with Yamaha's Thrust Enhancing Reverse Exhaust system, which delivers increased prop grip and thrust for improved maneuvering in docking situations and reversing up to your next big catch.   

Another cool feature is the new Total TiltTM system which allows the outboard to fully tilt up and down from any position, with a simple double push of the Up or Down Tilt buttons. This not only makes operation easier, but the new mounting bracket system allows the engine to sit higher out of the water when not in use, for improved long-term durability and protection. 

When combined with Yamaha’s Helm Master EX control system, the new V6 Offshore F300 delivers a boating and fishing experience unlike any else on the water.

Please note:  Yamaha Australia requires that all Yamaha outboards sold must be fitted by the selling Yamaha dealership. This is the only way to protect your warranty and guarantees the best performance from your Yamaha outboard.
