All right here is the deal. Started up the boat. Changed my oil last night after being stored all winter and the oil that was drained looked like a chocolate milkshake (not vanilla). Installed fresh oil and filter, ran for 10 minutes, no milk. Took it in to my local engine guy (with old oil and filter) and he said that it looked like his racecar engines after sitting all winter in the cold. He said it was just condensation and there is nothing to worry about. Anyone in the Midwest experienced this? The oil was not over-full either. Any thoughts?

Could I possibly have reversion? How can I tell? Will the spark plugs look diferent from the rest?

My sparkplugs were wet when I pulled them out. I had bad exhaust and a bad head.

I would check that to be safe, and then run it and take frequent checks on the dipstick, every few minutes for awhile, then less frequently if it checks out ok.
