Hello all,

Last weekend I was winterizing my boat and found that oil was brown and on spark plug was wet. I?m not sure if water wet or oil ? may be mixed.
What should I do and who do I check if there is a leak?
One more interesting thing that I noticed before I changed oil I check the oil level and it was fine. I pump out 1 gallon and put there 1.5 according to the manual and level was fine again. Where the .5 gallons of oil go? How is this possible?
