Ok I also have this posted on iboats. I am a first time boat owner. I bought a 1994 G3 aluminum boat with a 1978 Mercury 1150. I was told it couldn't be started because gas had been left sitting in it. Plus no battery. I pulled the lower end to check the impeller due to it sitting for (one year). I found a major mess. The impeller is melted, small amount of sand around the impeller, and the impeller cover melted in places with heat blisters all over. I'm looking at changing impeller, impeller housing (upper and lower) and all gaskets. What else would need to check ?
Ok have a little info on compression. Still no battery so I grabbed the pull cord and went to pulling
Cylinder 1 105
Cylinder 2 110
Cylinder 3 110
Cylinder 4 105
Cylinder 5 112
Cylinder 6 105
I know using the pull cord isn't the proper way. Just what I had for now.
I had a day off so I got to dig deeper. Here is what I found from bottom to top. Starter bracket broke and missing. Choke took loose or something. Carb baffle / choke plate melted. Merc switch wire cut. Gel on back of switch box melted. Throttle stop missing. I also found 2 metal parts laying in the bottom. I found where they go, but I don't have a clue what they are for.
