How do I dissolve corrosion between upper and lower outboard unit so
to get at the impeller?

I took all five nuts off (125 mercury sal****er) the studs holding the
lower unit on. I had to use penetrating spray to get the washers off.

After whacking the seam dividing the upper and lower with a rubber
hammer till blue in the face I etched/scored/scratched the seam to
allow penetration spray to work in, nothing.

After 24 hours of repeated spraying whacking and more scoring, the two
halves still won't come apart. Short of pounding in a chisel (gouging
aluminum), and prying them apart, anyone have an idea?

Use a sharpened straight putty knife as a wedge between the halves. Once
you see a gap you can use a wide chisel. Don't rush it it will come
apart with minimal scarring. File down the boo boos on the mating surfaces.

Try heating just one of the parts, a gas welding torch gives a lot of
heat in a small area. In Des Moines, one supermarket chain has dry ice
in a vending machine for two bucks a pound. Chill and then heat one
half.

Heating is going to ruin the paint.

I have used the putty knife followed with a chisel successfully on i/
o's. Really gop up the steel parts with antisieze when you put it
back together.

Can be the drive shaft corroded to the power head. May have to cut a hole
in the leg and then cut the shaft. replace shaft and have leg welded.
Also, I had to have the chips in the leg welded on a Mariner 15 that did not
want to come apart and had to pry apart.

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.

You do know that once you remove the bolt that holds the trim tab on
that there is another fastener underneath it that holds the lower unit
on.

Try a boating discussion board. Rec.Boats is a vehicle for right-wing
trash to whine about President Obama and for those few of us centrists
or slightly left of center here to laugh at the righties.

Don't forget to leave a bit of beef for rec.boat's right-wing
conservatrashers and ID spoofers to feed upon. The more they feed, the
quicker rec.boats will fall into the black hole of cyberspace and disappear.
