5-3/4" Poly Flex Heavy Duty Flexible Shaft Coupling for Allison and Capitol Marine Transmissions with 1/2" Bolts (P616 1/2-4-95-BLUE)

**This item has 1/2" Bolts, for older Allison & Capitol transmissions. Newer ZF and Twin Disc transmissions usually use 5/8" bolts. Please verify your bolt size.

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.
