Hi, I have a 58 johnson qd19. Replaced the clutch dog and have to put the skeg back on. Do I completely fill the cavity with scotch weld before adding spaghetti gasket? Do I pit the gasket first? Do I put the scotch wrld on the other part that fits together with the skeg? Also, I understand that I should put abit of scotch weld on the bolt, is that right? Specific instructions would be appreciated as I don't know much about rebuilding motors yet. Thanks!
