I have some green nasty sludge that drips from my lower unit after I run the motor (63' rude sportwin). Any idea what it might be?

Possibly a bad seal with your lower unit oil bubbling out?
Never seen it that color though

I just flushed the lower unit oil today and that was full nd it wasnt the same color. Its coming from a hole on in the lower unit but to me it looks like its a drain hole or something. It's perfectly round ....

I'll put pictures up tomorrow,
It could be draining from the crank case, the older omcs vented right into the water. Is it partially burned oil fuel/sludge? Make sure its not lower unit oil, but then there's only one other thing it could be. Maybe disassemble and clean your exhaust.

Now this has stumped me man!
Let me get with a few of my boat mechanic buddies and I'll get back to you on it!
