Hi John, Why did your yard want to cut the shaft to install the PYI shaft seal? That doesn't make any sense to me. It might be hard to get the coupling off but if that is the case then you can cut off the coupling leaving the shaft reusable (be sure to cut the coupler where the key is located in the shaft so you don't cut into the shaft itself) and then you just need have a new coupling machined to fit your shaft. I put a PYI on my C&C 34 and am very happy with the results! Not sure on the 36 but on my 34 the shaft is offset so it fits past the rudder without pulling the rudder - I don't even need to remove the folding prop off the shaft. PYI does recommend replacing the bellows every 5 years and I am due for that so it is on the agenda for this year. It also does need some adjustment initially to get the compression right but once that is set, I didn't need to touch it for 5 years (until 3 of my engine mounts failed this summer - engine shifted forward when in gear and resulted in water coming in while motoring but that wasn't really the PYI's fault.
