Isoflex Flexible Coupling IFC-4550-HT-5"

5" Isoflex Flexible Gearbox Coupler for Yanmar and ZF Marine Transmissions.

The IFC-4550-HT is the high-torque (HT) version of the 4550-series 4-bolt coupling. It maintains the same physical footprint as the IFC-4550-95, but uses a higher durometer / reinforced polymer disc to significantly increase torque capacity.
