Grady-White boats use Yamaha outboard engines. Grady-White has a long, exclusive partnership with Yamaha, so every new Grady-White comes rigged with Yamaha four-stroke power straight from the factory. Smaller Grady-White models run a single Yamaha, while larger center consoles and cabin boats carry twin, triple, or even quad Yamaha outboards. Pairing every Grady-White with Yamaha means the boat and engines are matched and tested together for the best performance, fuel economy, and reliability. Yamaha also backs its outboards with a three-year warranty, which adds extra peace of mind for Grady-White owners.
