Engineered Marine Products 93-93203 Engine Coupler Assembly for MerCruiser Alpha

The Engineered Marine Products 93-93203 is a triangular-style engine coupler assembly designed specifically for MerCruiser stern drive applications. This essential drivetrain component connects the engine flywheel to the stern drive unit, transmitting power while absorbing vibration and shock loads.

Key Features:

• Triangle-style coupler design for GM V-6 and V-8 engines (305 and 350 CID)
• Fits engines with 14-inch flywheel and 3-inch crankshaft bolt pattern
• Compatible with 1-piece rear main seal configurations
• Includes complete hardware: engine coupler, 3 rubber bumpers, 3 screws, and 3 washers
• Designed for MerCruiser Alpha One, Alpha Gen II, and Bravo LX model transoms
• Works with Mercury Marine MCM 3.0L (1999 and newer) and 4.5L MPI engines
• Fits GM V-6 and V-8 engines (1993 and newer) with Alpha stern drives

This coupling assembly replaces OEM part numbers 18643A5 and Sierra 18-2323. The rubber dampers absorb torsional vibration and provide flexible power transfer between the engine and stern drive, protecting both components from shock damage during operation.
