I have owned 3 boats and completed 4 west coast to/from Hawaii crossings with PSS shaft seals installed. Calypso has had hers since 1999.
I read of a specific failure caused by lack of maintenance where a boat sat for many years allowing marine growth and corrosion to bond the SS and carbon together. Someone started the engine to move the boat without inspecting or burping the PSS Shaftseal. The engine spun the shaft ripping the bellows. I inspect the shaftseal and burp it after each significant length of inactivity. I replace the bellows every 7 to 10 years. If a boat owner was unable or unwilling to inspect and maintain this type of shaftseal the more traditional stuffing box may be a better option. Full disclosure; I know and have sailed with PYI’s owners and have toured the PYI shop. I have not and do not work for them nor sell their products and strongly recommend contacting PYI directly for the most accurate maintenance and installation info.

Has anyone on this list experienced a PSS catastrophic failure (that is the fault of PSS) or have direct knowledge of someone who did? Installed PSS 4 years ago. Maintenance free = more time sailing.
