"In fall of 2008 I paid a respectible marine shop to winterize my motor. ($180) They wound up fogging the carbs on my 4 stroke, and didnt drain the float bowls. Heard this was a no..no? This led to problems in the spring of 2009.
So I decided to winterize this year myself. I found the engine oil was BLACK. Looked like the oil from a car which had 5000 miles on the oil. Can 10W-30 engine oil get black in 1 season with 50 hrs tops? (2007 motor)
Another thing I found...I think he put on a faulty Merc fuel/water separator...which had a solid rust ring on the outside of the seal. Changed that in the Spring of 2009 when I saw the rust.
When I changed lower unit oil, it looked brand new. Still yellowish in color. No water. Puzzles me how the lower unit oil could look so new, and the upper engine oil be so black?
Doing this myself from now on.
Just some advice I didnt do myself. Always check your oil levels after you get your boat back from servicing. Look to see if they greased all fittings, and double check your filters. This might save you a problem come spring."
