Introducing the R & D Flexible Shaft Coupling, a robust and versatile solution for your marine drivetrain. This coupling is designed to ensure the longevity and reliability of your boat's engine and transmission system. Crafted from a contoured flexible disc molded in resilient polyurethane, it offers exceptional flexibility to accommodate temporary misalignments caused by structural flexing or engine movement. Its forward and reverse thrust is managed through compression, providing a fail-safe design that maintains drive in both directions even in the event of a disc failure.
  • Flexible disc for reduced vibration and misalignment
  • Compression-based forward and reverse thrust management
  • Fail-safe design for continuous drive operation

With a capacity of 5HP/100RPM, this coupling is designed to handle the demands of high-performance engines. Its contoured disc allows clearance for bolt heads, while the polyurethane material ensures durability and flexibility. The coupling also features two metal compression straps for added strength and stability, providing a constant compression regardless of the drivetrain's direction.

  • 5HP/100RPM capacity for high-performance engines
  • Resilient polyurethane disc for durability and flexibility
