RE: hydraulic cylinder rebuild

re: prop shaft support

We also have had issues with this. Last year while cruising, I picked up a plastic bag in the East River and couldn't get it off for several hours. I thought it had wrecked our shaft bearing, only to figure out later that the cavitation had rattled loose the bolt that runs athwartship through the fin. So the whole strut was loose. Had water coming in etc. To make a long story short, once we tightened the bolt all problems (and leaking) went away, with no apparent long-term effects to bearing or shaft. It did, however, cause me to keep a close eye on this. We recaulked it over the winter, put some locktite on the nut, and will see how it goes. I have one friend here who says he had a similar system on an X-boat and that he eventually scrapped it in favor of something that bolted through the hull, but I'll have to see more serious problem before I go that far.

Re: prop shaft support:

On my Pac built boat (SN 26) the support is a fin that is an inset blade into the hull, retained with a couple of cross pins and the whole assembly is fiberglassed on the inside to form a closed pocket. My original unit had gotten quite loose and was leaking in the boat. The yard reset the whole assembly about 3 years ago and it has been fine since then. These is a very small amount of side to side play now in the support, but the yard says forget it, it is not worth trying to fill the slot.
