Quicksilver Engine Coupler Kit
The Quicksilver Engine Coupler Kit (12632A7) is a genuine OEM replacement part manufactured by Mercury Marine for Mercruiser sterndrive engines. This flywheel-mounted kit provides a complete solution for connecting the engine to the drive unit on GM 4-cylinder engines equipped with a one-piece rear main seal. Its triangular shape and flywheel mount design ensure precise fitment and reliable power transfer for Mercruiser Sterndrive 120/2.5L and 140/3.0L engines built between 1987 and 1993.
This kit is a comprehensive assembly that includes everything needed for installation: coupler 12632A6, yoke assembly 59830A7, all coupler attaching hardware, and yoke O-rings. Purchasing this kit eliminates the need to source individual components separately, simplifying the repair process and ensuring all parts are properly matched. As a genuine Quicksilver OEM part, it meets the original equipment specifications set by Mercury Marine for these applications.
The 12632A7 is a recognized cross-reference replacement for several aftermarket and OEM alternatives, including EMP coupler 94-93600 and EMP yoke 94-02421 (together as one item), Sierra 18-2195 Coupler Kit, Sierra coupler 18-2321 and Sierra yoke 18-2146 (together as one item), and the earlier Quicksilver 12632A3. This makes it a convenient single-part solution for boat owners and marine technicians looking for a verified OEM fit.
