About this product
The R & D Marine Flexible Shaft Coupling is designed to protect a boat's drivetrain by reducing noise and vibration. This coupling fits between the transmission output flange and the shaft coupling, helping to compensate for temporary misalignment caused by boat structure flexing or engine movement on vibration isolation mounts.
Constructed with a resilient, contoured polyurethane disc and backed by two steel compression straps, this coupling provides a fail-safe design that maintains drive in both forward and reverse. The polyurethane disc acts as a shock absorber for gear changes or propeller impact, protecting the transmission from costly damage.
- Fits 4 in. B/W and Hurth transmissions
- Capacity: 5 HP per 100 RPM
- Reduces drivetrain noise and vibration
- Absorbs transmission shock loads
- Fail-safe design with steel compression straps
- Model number: 910-001
Calculating Required Coupling Power: To determine the correct coupling for your engine, use the following formula: (Engine Horse Power / Engine RPM) x Reduction Ratio x 100 = HP per 100 RPM.
