The R&D Marine Flexible Coupling consists of a flexible disc molded with a Polyester Elastomer. The disc gives clearance for 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 mount. Forward thrust is taken in compression on the disc between the two half couplings and reverse thrust is taken again in compression on the disc between the two fail safe straps. In the unlikely event of a severe impact, the steel straps make the coupling fail safe and ensure drive is maintained both forward and reverse.
Fits brands such as Borg Warner, ZF-Hurth, Twin Disc, Volvo, Yanmar, Technodrive and more!
