Looks normal to me. The part that you think looks overheated is not in
contact with anything. You do need to do a minor alignment. The shaft needs
to go in all the way with very little force.

I pulled my outdrive to check the alignment.
(2002 Mercruiser Alpha One outdrive.)

I've never done this before but I'm a machininst and a half assed
mechanic, so I think I can handle it.

My first question is....in the picture you can see that it looks like
the shaft has taken some heat judging by the coloration of the shaft.

Is this normal or is this due to overheating because of misalignment?

The alignment tool only goes in about a third of the way into the
coupling before it binds up. My second question is I'm wondering how
bad the alignement is if the tool goes in freely at least a third of
the way, it seems that that must be pretty close. Is that offalignment
bad enough to have overheated the shaft?

TIA,
