86 mariner 75hp 4cyl. 1 broken head bolt... slight water comming out of broken bolt (broke half way thickness of head.. slight water comming out of where broken bolt. and where the head and block meet... cleaned carbs 2 hours ago... runs good. when i shut motor off about 5 minutes later the bottom carb has milky gas/oil laying before air jet? it is before the black thing in the middle of the carb towards air box cover... does you guys think this is water comming out of water jacket, running down the cylinder through the butterfly on carb and leaking out? head bolts are rusted dont want to try to take them off until offseason, winter.. if this is where itis comming from do you think i will bend a rod running it for a few more months.. motor does have a sight sputter at idle but barely at all. she does run good. oh the reason i cleaned the carbs was becuase of this and i the motor/boat sat for about 5 years..been out with it 3 times. broken bolt between cyl 2 and 3
