We have all heard horror stories of boats sinking when a coupling breaks and the shaft is ripped out of the boat. The PYI Shaft Retention Collar is designed to help retain the Propeller or Rudder shaft in your vessel in the event of catastrophic failure of the coupling or if the shaft comes free from the coupling. The double split design provides the maximum in axial holding power with the benefit of quick and efficient assembly with the shaft installed. Design fully engages the shaft without marring. Very simple to retrofit to existing prop shafts and rudder shafts. A cost effective and quick solution that could save thousands.
