Keep the shaft in the boat.

Shaft Ring Collar with Packing Gland

Shaft Retention Collar with Packing Gland

We have all heard horror stories of boats sinking when a coupling breaks and the shaft is ripped out of the boat. PYI has a simple solution to assist in keeping the shaft in 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.

Shaft Ring Collar with Packing Gland

Shaft Retention Collar with Mechanical Face Seal

Design fully engages the shaft without marring. Easily installed where major disassembly would otherwise be required. Greater axial holding power than set screw or one-piece clamping collars. Effective on hard and soft shafts.

Very simple to retrofit to existing prop shafts and rudder shafts. A cost effective and quick solution that could save thousands.
