V8 5.3L 350 hp

The F350C is an engineering achievement. Its impressive displacement and advanced valve train increase power and throttle response, easily producing 350 hp and generating incredible torque between 2000~3500 RPMs. And it’s all about torque when you have a large offshore boat. It’s the power to get you on a plane, and owners will tell you there’s nothing that does that like Yamaha’s 5.3L V8 F350C outboard.
