I recently purchased a Starcraft 1700 that has a Johnson 70 Seahorse motor on it. The boat and motor have been setting outside for a few years unused. I tried starting the boat and it did not want to start. I took the plugs out and noticed the bottom plug had a good bit of milky looking liquid. The middle plug had a little bit and the top plug just looked a little wet but pretty normal. Do you think it could just need the old gas removed and let the cylinders dry out? I am thinking that maybe it just took on some water in the tank and that is causing the milky looking liquid, which would keep it from firing. My other question is why would one cylinder have a lot more than the other two, unless the weight of the water is just sinking? Would a bad head gasket maybe be a culprit? I have never messed with a boat motor before and do not know where to start. Were these pretty good motors and is there anything else i should look for or check on it? Thanks for the help!!
