All the ones I have pulled apart that shaft goes through a seal into
the area where there is gear lube. But that's on i/o's. Maybe it's
different on outboards.

I have had outboards be a little cranky but never had to pry one
apart.
Start the nuts a few turns so it won't drop and kick the gear housing
"bullet" on each side. That will rock it and break it loose most of
the time
If it was one of the shafts corroded up you would still have a little
free play. My bet is still the locating pins.

The bolts, if stainless, cause a reaction with the aluminum housing. the
resulting white oxidation wedged tightly in the gap causes the binding.
Grease or never seize will prevent the problem in the future. Wedging
the halves apart is the best solution in stubborn cases

I can see daylight between the upper and lower now, at last toward the
prop end. I don't think the corrosion where the halves come to gether
so much as in the threaded studs or where the shaft goes into the top
end.

I've been using a chisel at the narrow end, above the prop. That's
where I can see through to the other side. At the risk of gouging the
other end, toward the stern, I may have to gouge it up a bit.

The anti-corrosion spray can only do so much if the shaft is corroded
into the gearing up top. (I don't know the technical jargon).
