All Holley Marine Carburetors are designed to meet Coast Guard specifications. A marine carburetors fuel metering system is calibrated to compensate for unique engine loads found on boats. The J-style vent tubes direct fuel/fumes back into the carburetor for safe operation while on rough waters. The Holley 0-80319-3 Marine carburetor is designed for Ford Marine 351 CID (5.8L) engines.
