R&D MARINE Flexible Coupling for 5" Borg Warner, ZF, Hurth, Volvo, PRM, Yanmar (20 HP/100 RPM Capacity)
The R&D Marine 910-029 is a flexible shaft coupling designed for 5" gearbox flanges used in marine propulsion systems. Compatible with Borg Warner, ZF Hurth, Volvo, PRM Newage, and Yanmar gearboxes, this coupling provides reliable power transmission while absorbing shock loads and compensating for minor shaft misalignment.
Constructed from polyester elastomer material, the 910-029 is resistant to salt water, diesel fuel, and marine lubricants—making it ideal for harsh marine environments. The coupling reduces engine vibration and noise transmission to the propeller shaft, enhancing overall drivetrain comfort and longevity. Installation is straightforward, requiring no machining, as the coupling comes supplied with all necessary bolts for connection between existing shaft flanges.
