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 0-80552 Marine carburetor is designed with a universal calibration good for marine engines where a spreadbore 4BBL is required.
*** A carb spacer may be required to allow the fuel inlet on our marine
4175 to clear the water manifold (aka thermostat housing) on most
Mercruiser and OMC GM V8 engines.
