R&D Flexible Coupling 910-002 YANMAR 9119 MMP SAILDRIVE are built inManufactured by R&D Marine, the flexible coupling fits between the boat propeller shaft coupling and the gearbox output coupling. This flexible coupling consists of a contoured flexible disc moulded in tough yet resilient new type Polyester Elastomer. The contoured coupling disc gives clearance for bolt heads, and allows the coupling to flex freely to take up any temporary misalignment of the engine and propeller shaft, due to flexing of the boat
