I have a 1990 merc. Just below the cowl on the back of the motor are two rectangular vents. What are these for?I think I have some kind of oil -water mixture coming out of these!

You must first find out what the problem is. Over oiling, fouled spark plugs, carburetor adjustment, these are possible causes of your symptom.Regards
