Flexible Coupling Install goes well


Installed the R&D Marine 910-014 Flexible Coupling on my 1988 Catalina 30 with a Hurth HB50 transmission. Also installed the Earthing Connectors - 103-037 to maintain continuity to the shaft. Was very easy install. Haven't run with it yet as the boat is on the hard for the winter.
