Hello all, I am new to this forum, so thanks in advance for all the information all ready on here. A friend and I have acquired an early '70s model 9.5 evinrude sportwin. The old jewel hasn't been run in a long time. I have rebuilt the carb, replaced the thermostat and water pump, and rebuilt the fuel pump. I had run it before doing anything of this stuff to it, and it would only run with the choke fully on, and poorly at that. Now today, I got her started and was trying to adjust the fuel/air mixture to get it to idle better when she died and would not start back. After a little head scratching, I pulled the spark plugs to check for fire, and noticed the bottom one had water on it. I then pulled the head and the bottom cylinder had a bunch of water in it. The head gasket looked ok, but I thought the bolts had seemed loose, so I dried the cylinder out and tried it again... Same routine, after running about 10 minutes, the bottom cylinder was full of water. Has anyone ever seen or heard tell of this happening? I am about to order a new head gasket to try, and I can chemically magnaflux the head where I work.... Is there something else I should be looking at? Exhaust valves maybe...?
