The carburetor body is made of cast aluminum, while the float bowls and fuel inlets are made of brass, which is known for its excellent resistance to corrosion and its ability to maintain a consistent temperature.

The 807312 carburetor's design incorporates several advanced features, such as an electric choke option and a vacuum secondary system. The electric choke option provides quicker engine starts and easier cold weather operation, while the vacuum secondary system ensures smooth power delivery during acceleration.

In conclusion, the Mercruiser 807312 carburetor is a high-performance, 2-barrel carburetor specifically designed for MerCruiser engines.
