Thanks to the list's advice last week about getting the bolts loose on the
universal to shaft coupling, I got them all out with an impact wrench. Worked
beautifully. But now I am stuck again getting the shaft coupling off the prop
shaft. Removed the bolts that grip the coupling to the shaft and also a
square-headed bolt in the coupling that probably fits into a keyway in the
shaft, but I can't break the shaft loose from the coupling. I tried holding
the coupling from turning with a pipe wrench and trying to turn the prop shaft
(by gripping the sacrificial zinc on the shaft with a big vice grips so as not
to damage the shaft itself), but it didn't budge. And of course I don't want
to damage anything.
One possibility would be to slide the shaft as far aft as possible (since it is
disconnected from the universal and the SS PYI piece (that acts as the bearing
up against the bellows) that is on the shaft slides forward on the shaft) and
then get a small wheel puller on the coupling so it would push the shaft out of
the coupling. I have no experience with wheel pullers but it seems that it
might work.
But I would really value input from the list about how to proceed. Apparently
the salt water leaking around the bellows this summer rusted the coupler
sufficiently that it is really stuck.

Eric,
I recommend Jims' suggestion of using longer bolts and a socket. It
worked for me. Make sure that you tighten the nuts evenly so that the
force on the coupling halves stays in a straight line.
