I agree with Josh, my PYI would be perfect if it could be changed without haul out! I am trying to imagine the circus in the rear stateroom of my 37+ if you tried this change in the water! The failure rate of this PYI system seems to be nearly negligible, the pressure on the mating surfaces is so minimal! I wonder if a temporary perfectly flat shim of carbon with ears (or other slippery material)could be quickly installed that would replace the pressure of the plates against each other….. Failure of the bellows, or the set keys, may well eliminate mechanical propulsion if you are off shore. In shore you would need most of that bilge pump capacity you had invested in. I haven’ seen the “Sailor Sam’s” but I will watch for it. I am also a big fan of this company so I am not running down their products, but cognizant of limitations of the system. Love the Max-Prop thus far. Cheers Rick Rohwer Paikea 37+ Tacoma, WA
