Thanks again, everyone. I think I'll schedule a weekend on the hard right after Memorial Day weekend. I can take Friday off from work, get them to haul and block her, and take my time to make sure it's done right. There are only three through-hulls on the boat, and I'll feel a lot better if this is taken care of.
Shaft seal - she has an outboard, so no shaft to seal.
Rudder stock - there's a bunch of play in the tiller, but it seems like the entire assembly moves. Here's a picture:
The poorly-drawn green arrow is pointing to a base plate. Even the base plate slides around when I wiggle the tiller assembly. Not sure of the best way to fix that....
Through hulls - I was planning to replace them at the same time as I replaced the gate valves. As long as she's hauled, what's another 60 bucks?
