The stern tube is threaded and the flange is screwed onto it.

The stern tube is held in by caulking.  If unscrewing the flange can 
turn the stern tube in the caulking, it's not being held very securely, 
already.  If it turns when you try to unscrew the flange, you'll need to 
redo it by cleaning out all the old caulk and recaulking with 5200. 
Mike has done this job on a couple boats and can give you more details 
(or search the message archives).

Mine used 3/16" packing.  You might be interested in the drip-less 
packing--see

I've just put that on, but Mike's used it for years.

It depends on what you've got.  I have a Camp ZN-1 zinc 
(http://www.alberg30.org/maintenance/disorganized/propnut.gif) and I 
have to trim the point to clear the rudder.  There are other kinds of 
prop nuts for zincs, too.
