I have been replacing my neighbors risers the past few days for they was leaking raw water into the cyl's. The risers appeared to be the issue with water leaking. The 3" snout was rusted off and just sitting in the elbow. Well I got it all finished up to day and replaced the starter(bendix broke in old starter) and before I put the plugs in I spun it over and all seemed well. Installed the plugs and started it up. It started up alot better and sounded better as well. Ran it for 10 min with no leaks and shut it off for 30 sec and started it back up with no issues. I did this a few times and I thought the risers was the issue so I shut it off. 15 min later went to start it back up and the mother &(^%(^ was hydro-locked once more. Needless to say I called it a few foul names. I started to pull the plugs on the port side and the was all full of water. I ran a compression test and # 1,3,7 was 150-160psi and #5 was 90 psi. Didnt do starboard side was too upset but know it spun over freely with plugs out on port side. Could this just be a head gasket and/or intake gasket? Or should we just pull it and rebuild it. Dont know the hours for there is no hour meter 'YET'. Any thoughts?
