I found water in the oil after the summer, bringing it home to winterize in the fall. The oil looked like chocolate milk. Did not look this way in the spring.

Today I went over to the lake and pulled the plugs and did a compression check. All above 160. Put new plugs in and ran the boat for 20 minutes on the trailer. No sign of water on the dip stick, but it was hard to tell. I will go back over, drain the oil again and repeat, only letting the boat run longer.

Any thoughts?
