I have a 1986 50 hp evinrude, model CE50BELCDE.<br /><br />It has been missing at an idle, eventually stalling. It also bogged down for twenty seconds or so when the throttle was opened up. <br /><br />Rebuilt the carbs, new plugs and wires - this all helped a bit. Compression was 119 on top and 121 on the bottom. Then I decarbed with omc engine tuner,then things got worse.<br /><br />Now I have water in the top cylinder ?<br /><br />I am thinking this is a head gasket - any help would be greatly appreciated.
