Prestige Motorsports - Chevy Big Block Marine Series
Our Marine development team incorporates dyno charts, testimony from boat builders, and real-world conditions from Florida, Louisiana, and Texas, to design engines around your boat performance needs. We look at the extended periods of time that a Marine engine is under heavy load and design the engine for specific RPM ranges, concentrating primarily on low-end torque and mid-range power. The resulting Marine engine packages deliver performance that’s hands-down better than anything you’ve used before. For builders, we also offer a dealer discount.
