Details

The XTO Offshore 450 is Yamaha's flagship, a 5.6-liter V8 built for large offshore center consoles running twins, triples, or quads. It sits in a different class than the rest of the range: direct injection for diesel-like low-end grunt, integrated electric steering that cleans up the rigging on multi-engine transoms, and internals engineered to be serviceable in the water. If you are stepping up to a serious offshore platform, this is the top of the lineup.

Boston's leading full service vessel management company. Sales, service, repower, transport, and storage you can rely on.
