Done the fogging and drained the lower unit in the fall just didnt get to the oil change.
Undid the oil drain plug yesterday... noticed what I think was water
 
   (or could have been fuel from when I turned the motor over while fogging)come out first then some perty black oil.  Unforutnatley was not ready for the volume the oil poured out at.. so some of it hit the floor, so I could not inspect the pan for water.  The oil was not milky or anything... nor was it milky last fall when I would check it...

Motor ran as smooth as glass... dont think I have a cracked head or broken gasket...
What do you think?
UPDATE:
Think I solved my own mystery... used a heavier grade of oil (20w)to fog my engine in the fall. Sounds like it settled to the bottom of the crank case. Was still pretty clean... Looked like water...
Thats why the oil wasn't milky..
DEAR MERCURY:
I PROMISE TO CHANGE MY OIL MID SEASON!
 
	


 Jimmy I'm confused now. What did you do to winterize your engine. I have mercury outboard certification na d am a bit bewildered by your explanation. Did you drain the oil and not replenish it? I have read and reread your post. I am trying to figure out how the oil you used for fogging could get  into the crankase. I think what you saw was condesation not oil. I suspect you put some oil in each cylinder and turned over the engine. Now if that oil got into the crankcase that would mean that crankcase oil will get into the combustion cahmber and thatn is not good. Was all the water drained out of the motor beforing storage???
