R&D Marine Flexible Coupling 910-012 for Yanmar

Ideal Flexibility for Your Propulsion System

The R&D Marine Flexible Coupling 910-012 offers a reliable connection between the boat's propeller shaft and gearbox output coupling. Made from a tough yet flexible Polyester Elastomer, this coupling features a unique contoured design that accommodates bolt heads and allows for free flexing, compensating for any alignment issues that may arise due to the boat's structure or engine vibrations.

Enhanced Safety and Reliability

This coupling is designed with safety in mind. In the rare event of a coupling disc failure, the integrated steel straps ensure that propulsion is maintained in both forward and reverse, making it a fail-safe option for your vessel.
