Established in 1973, R & D Marine has developed a comprehensive range of failsafe competitively priced engine mountings and flexible coupling to fit all major installations.

Shear mountings are available where good isolation is required and compression mounts where there is a restriction on the available space.

Made from a polyester elastomer which is not affected by salt water, diesel and lubrication fluids,
the R & D flexible couplings reduce engine noise and vibration transmission.
