All the V8 power you ever dreamed of!

There have simply never been engines like this before.

The 5.3 litre Yamaha F350 and F300 are the first-ever 4-stroke V8 outboards. Backed by Yamaha’s awesome technology, you get a total performance package. Designed and engineered to deliver that raw energy you need to power a large, modern offshore boat, and these engines deliver it with smooth, quiet refinement to match today’s ever more sophisticated, soft-riding hull designs.
It’s a new level of engineering excellence and innovation that’s totally revolutionary. Totally remarkable. Totally reliable. In a word, Yamaha.

Only Yamaha, with its unique market-leading position and legendary record of innovation, could have made the dedicated investment necessary to bring you such engines. Make no mistake. This is an entirely new and revolutionary approach to the powering of larger boats, with engines specially designed to withstand the harsh demands they face.

Supremely advanced 4-stroke technology, V8 configuration, huge torque and prop shaft horsepower - all come together in the F350 and F300 to deliver levels of dynamic performance never before achieved in any production outboard.

Providing unparalleled power and torque to move even the heaviest boats, the F350 and F300 deliver massive thrust and speed, but with incredible style and reliability.
So it’s go-anywhere time!

The 60° V8 configuration and unique In-bank™ dual exhaust system allowed us to create a revolutionary internal engine shape and layout. Result? A beautifully streamlined appearance and a stylish, powerful-looking design that will really turn heads when you park up.
