MIKE IN lINO III Posted August 11, 2008 Share Posted August 11, 2008 I have an older Johnson outboard. I have no idea what year it is or the HP. I put it on my duck boat this weekend and it runs like a top. One problem is that the water used to cool the engine is not spitting out the correct area. It is coming from the engine dept. right under the second cylinder and it looks to have exhaust mixed in it as well. At first I thought I might have a bad head gasket but the thing runs perfectly smooth. Anyway, it is a Johnson Model # AD-11, Serial # 1596263. I want to get a manual to see what the possible problem is. Thx, Mike Link to comment Share on other sites More sharing options...
