most of the head gasket came off, but I'll try to scrap some more. Was going to wait until the motor is out of the boat to use my little high speed sander air tool with the scotch bright discs.... I'll crank the engine over and lower the piston down to bottom then take another pic. It almost looks as if I lost a valve seat or something, but the head on there is okay??? I'm wondering if the previous owner screwed me here a little since this motor never had the power it should have, and only recently starting huffing smoke... I wonder if the piston was coming apart but decided to go all the way....
