I would not do it, because you would have to get new set screws and reset it
in the spring. I am leaving mine intact.

Subject: Stus-List winterizing the PYI shaft seal
Practical Sailor recently posted a suggestion for winterizing the Dripless
PYI shaft seal. PS said to unclamp the SS rotor from the prop shaft so the
bellows could expand to its uncompressed state. I have never done this, and
with the recent discussion about the set screws holding the rotor in place
on the prop shaft, I wonder if it is worth it. Would be interested in what
other PYI users do. I did replace the entire unit last winter; at full
engine RPM I had noticed water spraying out between the rotor and the carbon
flange, perhaps because the thrust of the prop pushed the shaft forward
until the rotor did not make good contact with the flange. When I unclamped
the rotor and slid it forward to inspect, the bellows was very stiff and
there were some small pits in the carbon and the rotor surfaces. PYI
recommended replacing the entire unit, which I did, and it has worked fine
this summer. But it had worked flawlessly for the 8 years I owned the boat,
and looked like it had been installed well before that, without doing
anything to winterize it - just checking to make sure it was not leaking at
the beginning of each season. So what's the feeling about following PS's
suggestion?
