Simple to periodically check alignment Why you should buy R&D Flexible Couplings, 1. The R&D 910 Series couplings consist of a contoured flexible disc moulded in tough yet resilient new type polyurethane. The contoured disc gives clearance for the bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or the engine moving on its rubber vibration isolation mountings. In the unlikely event of a disc failure the steel straps make the coupling fail safe and ensure drive is maintained in both forward and reverse. This resilient polyurethane disk will reduce engine noise and transmission vibration, compensate for minor shaft misalignment, and absorb shock loads. From these measurements, magnetomechanical coupling factors are calculated. For engines up to 230 HP / 100 rpm @ propeller shaft. The company was started in a single garage moving to two garages after one year and then to its current location in 1976.
