Yamaha 5.3L V8 Offshore F350
Print Full SpecsOne hundred miles offshore, it’s truly man vs. nature. Corrosive saltwater. Pounding waves. Churning seas that can blow up out of nowhere. But there’s one thing nature wasn’t prepared for—the pure power and reliability of this machine, the Yamaha V8 F350. It provides all the thrust, torque and raw energy required for today’s larger offshore boats.
