5-3/4" Poly Flex Heavy Duty Flexible Shaft Coupling for Twin Disc and ZF Marine Transmissions with 5/8" Bolts (P616 5/8-4-95-BLUE)

Poly Flex flexible shaft couplings isolate and reduce vibration and the shock of shifting in and out of gear by providing a damper between the transmission and propeller shaft. Poly Flex couplings also provide a sacrificial link between the propeller shaft and transmission that when struck hard enough by rocks, logs, line, etc, is designed to fail in order to prevent or reduce damage to the transmission.
