My PYI bellows made it from 1988 to 2012 without issue. The face seal was a bit worn after all those hours though. I looked into getting a "normal" stuffing box but they did not have my size anymore, so I have a new PYI now. The spring in the hose is very important - you can't just use normal hose!

Besides, if they did, it would ruin their aftermarket for replacements!

I am a big fan of silicone hose, and have seen short connectors on powerboats with a pleat in the middle, but not multiple pleats. I have also seen a picture of a silicone (I think) bellows on European boat.

As you tighten the coupler on the shaft up to the other half the socket pushes the shaft out. If that doesn't work, it's usually cut-off wheel time. A better penetrating oil than PB Blaster is a 50/50 mix of ATF (automatic transmission fluid) and acetone.

Get two pipe wrenches - shaft and coupler. Heat and twist. If that fails, use a gear puller or make one with a small piece of 1/4 inch thick metal, drill holes to match the coupler and a threaded center hole for a decent size bolt. Bolt the plate to the coupler and use the center bolt to push the shaft out.

Worked beautifully. But now I am stuck again getting the shaft coupling off the prop shaft. Removed the bolts that grip the coupling to the shaft and also a square-headed bolt in the coupling that probably fits into a keyway in the shaft, but I can't break the shaft loose from the coupling. I tried holding the coupling from turning with a pipe wrench and trying to turn the prop shaft (by gripping the sacrificial zinc on the shaft with a big vice grips so as not to damage the shaft itself), but it didn't budge. And of course I don't want to damage anything. One possibility would be to slide the shaft as far aft as possible (since it is disconnected from the universal and the SS PYI piece (that acts as the bearing up against the bellows) that is on the shaft slides forward on the shaft) and then get a small wheel puller on the coupling so it would push the shaft out of the coupling. I have no experience with wheel pullers but it seems that it might work. But I would really value input from the list about how to proceed. Apparently the salt water leaking around the bellows this summer rusted the coupler sufficiently that it is really stuck.
