I have a question maybe somebody could help me with. I'm working on a 2001 75HP Mercury 4 stroke. Last fall I changed oil and found excessive water in the oil. I was told these engines run cool and get a lot of condensation in the oil. The motor has very low hours and looks brand new. The owner put about ten hours on it this past summer. I changed oil again and found excessive water in the oil again. There is no indication of any water or rust on any of the plugs. Has anybody had any experience with these motors? Where can water get in the oil besides the head gasket.<br /><br /> Thankyou Jerry
