Function

The drive plate performs several important drivetrain roles:

• Connects the engine flywheel to the drive coupler or transmission input shaft

• Transfers engine torque to the sterndrive or transmission

• Absorbs vibration and drivetrain shock using spring-loaded components

• Helps protect internal drivetrain parts during shifting or sudden load changes

The flexible design helps prevent damage to the coupler, gears, and input shaft during normal engine operation.
