I posted a video of a Martin that had water leaking from the water jacket gasket a few days ago. The head is part of the water jacket. I thought copper coat gasket sealer would be a good choice for the head gasket. Wrong. Didn’t run 2 seconds and I had water in the combustion chambers. Now I’m waiting for more gaskets. My nickname should be Two Timer because I do everything twice. By the way the brown stuff smeared on there is the original sealer. It’s still under the carbon after I remover it. Nothing takes that stuff off. Even steel wool doesn’t bother it much. Tubs.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
