R&D FLEXIBLE SHAFT COUPLINGS - [PDF Document]

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

Vibration; and what coupling is this? - ybw.com

2014-09-20· The R&D coupling shown by ghostlymoron is like what I had installed on my previous two boats (Vivacity and Centaur). That flexible disc is easy to set up and always gave a trouble-free performance. Should the OP be considering a replacement for the one in his picture, this is one that I would heartily recommend.
