12AA19 R & D Marine Engine Damper Drive Plate

Fitted between a boat engine and the gearbox input shaft, a damper drive plate is designed to transmit the engine power to the gearbox, whilst reducing transmitted gear noise and providing a cushioned drive when selecting gear. All R and D Damper Drive plates include a 'failsafe' design.

Also called the Driven Plate, Damper Plate or Clutch Plate, the 12AA19 Damper Drive Plate is from the R and D High Deflection element range. Common applications for the 12AA19 drive plate include certain Lancing Marine marinised engines with a PRM Delta gearbox, subject to flywheel dimensions.
