it was completly serviced (1995 3 cyl. merc 90hp 2 stroke)and then winterized ie. flushed ,, fogged,, and fuel stabilized,, NOW,, after two outings with a total of maybe an hour run time,, im noticing a film on the lower unit coming from the water intake hole where the ear muffs go on,, the boat does need a o ring for the oil resevior, as it leaks from the cap if i over fill it,,,, but it didnt seem to be 2 stroke oil,, it was a thicker slime,, my question is ,, is this normal after coming out of hibernation,, where does whatever it is travel from to get to the muff holes,, or do you think an internal seal is gone? thanx to any who help me... what is my next step to trouble shooting this problem?
