Quicksilver Engine Coupler 76850A2

The Quicksilver 76850A2 is a genuine OEM coupling assembly engineered specifically for Mercruiser sterndrive engines. This crankshaft stud-mount coupler serves as the critical link between the engine and the sterndrive unit, absorbing shock and transmitting power reliably under demanding marine conditions. It is compatible with GM in-line engines as well as V-6 and V-8 configurations displacing 283, 305, and 350 cubic inches, making it a versatile replacement part for a wide range of Mercruiser-powered boats.

This part carries cross-references for Sierra Marine (18-2171) and GLM Marine (11500), confirming broad aftermarket recognition of its fitment. It also supersedes several earlier Mercury/Quicksilver part numbers: 38965A2, 32492A5, 32492A1, 32492A2, 32492A3, and 38965A1, ensuring backward compatibility for older engine configurations.
