Enhance Your Marine Adventure with R&D Flexible Shaft Coupling
Experience unmatched performance and reliability with the R&D Flexible Shaft Coupling, designed for 4" B/W, Hurth with a 5HP/100RPM capacity. Crafted from a new type of tough, resilient polyurethane, this coupling boasts a contoured flexible disc that not only accommodates bolt head clearance but also ensures free flexion to correct temporary misalignments caused by the engine or boat structure flexing. This innovative design absorbs forward and reverse thrust in compression, ensuring smooth operation and protection for your boat's drivetrain. In the rare case of a disc failure, the fail-safe steel straps maintain drive functionality, making this coupling an essential upgrade for any marine vessel.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.
Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.
To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
