All owners of this engine regardless if it is a Yamaha or Mercury. Do yourself a favor it will take 2 minutes crack the engine oil drain plug to its last thread (so the oil drips out very slowly) what do you see?? Hopefully nothing<br />but pure oil. I am betting you will see milky oil approx 6 - 12 oz. Condensation I think Not !! Common denominator between Yamaha and Mercury = same powerhead = design problems. But merc says that a cupful of water in the crankcase is within acceptable parameters.....
