R & D Marine was started in 1973 and the basis of the product range was to established a comprehensive range of Flexible Couplings, Engine Mountings, Damper Drive Plates and Propeller Shaft Half Couplings for engines from 5 H.P. to 800 H.P.

The Engine Mountings have been manufactured to fit all major brands, shear mountings are available where good isolation is required and compression mounts where there is a restriction on the available space. 

They have also developed a wide range of competitively priced Flexible Couplings, the R & D Flexible Couplings reduce engine noise, vibration transmission and are designed to accept propeller thrust, a separate thrust bearing and bulk head is not required when using the R & D flexible coupling.The couplings are made from a polyester elastomer which is not affected by salt water, diesel or lubrication fluids.If electrical continuity is required an earthing connector can be fitted in the centre of most Flexible Couplings.

Also to their extensive range, R & D Marine have developed a wide range of competitively priced Damper Drive Plates to fit most engine/gearbox combinations. The R & D Damper Drive Plates reduce gear noise and allow the engine to run at lower speeds. Linear Stiffness elements for general applications and High-Deflection elements to stop gear noise and spline wear at slow speeds. All dampers are designed to be Fail-Safe and maintain the drive if the flexible element fails.The flexible elements are made from a Polyester Elastomer which has good heat qualities and is not affected by salt water, diesel and lubrication oils. Non-standard items are available for special installations, maximum back plate diameter of 533mm (21.0"). Installation is made quick and easy as the R & D Damper Drive Plate requires no machining and is ready to bolt to the flywheel.
