Man Janice, don't put the bad juju on me, talking shaft removal involves many boat bucks I'm sure. Have not had to find out yet.
Nope. Not a bit Old School. Mine had to come back so I could install the PSS, which I have now replaced with a standard. My PSS started leaking badly -- fortunately while on the way across the river to the boatyard for a haul.
It had given me fits twice before. Initial install, the guy (can't say mechanic because, well) anyway, there are two set screws for each hole. Only one was put in initially so of course those things vibrate out. I found one in the bilge -- and just one.
Lots of water too.
Then I doubled the set screws (had spares on hand -- handy to have something so critical, and where I could find it!) so when I spotted a set screw in the bilge I went looking and found the one that was missing.
Shoving the silver ring back wasn't fun -- required testosterone. Sigh.
The theory is good and I did want a dry bilge. Our steel boat had a box under the stuffing box and the bilge herself was bone dry. This was in the days before all those coatings they sell now.
On the first of each month every deck came up and the bilge was vacuumed. Dust is a magnet for moisture. And of course phospheric acid too any place required.
No, I'm sure yours is/will be fine.
