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

After 24 hours of repeated spraying whacking and more scoring, the two

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.

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.

Not on the 125 outboard.

Most outboards do.

Not any Mercury I know of

The bolt that you loosen to adjust the trim tab is the bolt that holds
the lower unit on?? Isn't that way on my Force, and it wasn't that way
on the Evinrude I had before. Makes me want to go take apart the
neighbor's Merc!!!

Not exactly, on a lot of Merc outdrives you have to remove the trim
tab to get a socket on the sixth bolt that holds the lower unit on.

I think outboards use only five bolts and removing the trim tab (bolt)
is not necessary.

Any outboard I ever had had a bolt that you had to take the trim tab off
to get to.

I took that off and looked up into the cavity, nothing. The 5th bolt
is right next to the trim tab going forward. That's ones out

There's a gap now which tells me the corrosion is in the gearing

The front


Some of the Mercurys have a design of shift shaft that needs to be
unscrewed before they will separate but I thought it was only a few
old, midrange 2 strokes.

I checked with the owner of the shop near me and he said it didn't
need to be disconnected. I called him so many times on stuff that I
finally sent him 2 pizzas to say, "thanks"

It is a threaded shaft with a shaft coupler and a lock nut right up
front, coming down from the top.

He showed it to me but said don't worry about it.


I doubt that is it but it is worth a look.

Can you get it to rock side to side?

at the gap?, no.

I'll be out of town until Friday. Hopefully all the spray I did will
have had time...when I get back

This is the scary part. If this is still just corrosion on the front
locating pin it won't cause any damage when it finally pulls free but
if this is the shaft coupler for the shifter, it could pull the shaft
out of the foot. There is only a single jesus clip holding it in. If
that happens, there is a very good chance the cam will fly out and you
are going into the foot to fix it. I would believe if that was what
was hanging you up there should be a little free play.
I assume by now you have all of the white powder out of the bolt
holes. One of those heavy duty dental picks they sell at harbor fright
can help there. WD 40 seems to soften it up.


Thanks, BB Friday, I'm off to DC
