High-Quality Marine Carburetor for MCM 502 V8 Engines

Introducing the premium Rochester Quadrajet 4 Barrel Marine Carburetor, specifically designed for the MCM 502 V8 8.2 Magnum Engine. This carburetor is a top choice for boaters seeking enhanced performance and reliability. With its electric choke upgrade, it offers a seamless and efficient fuel delivery system, ensuring optimal engine operation.

Robust Construction and Advanced Features

This carburetor is assembled using only the highest quality components, guaranteeing long-lasting performance. It features all new parts and gaskets, including a brand new electric choke, choke pull-off, float, needle, and seat. The castings are coated with a protective layer of black paint, while brass bushings in the throttle shaft eliminate vacuum leaks. The base is re-finished, and linkages and hardware are coated with yellow zinc to prevent corrosion. Additionally, casting plugs are sealed with epoxy to prevent leak-down into the intake manifold.

Our carburetors are flow bench tested and designed for Mercury Marine applications, including the MCM 502 V8 8.2 Magnum Engine. This product is a direct replacement for carburetor numbers 17089112 and Mercruiser #1347-814623A2, offering an upgrade to electric choke functionality. Our carburetors are also compatible with a wide range of marine engines, including 4.3, 5.0, 5.7, 7.4, and 8.2 Liter models. Whether you're a professional mechanic or a weekend boater, this carburetor is the ideal choice for ensuring your engine performs at its best.
