Universal m35 leak at drain plug
I have a very slow leak at the 1 1/8" diameter engine fresh water drain plug. It has a smaller plug within it, but does not seem to be leaking there. If I back it out a small amount and put polisulfide caulk on the threads and tighten back up, would that fix it? Or is there too much pressure. Or am I into something more involved. By the way I am only hoping I can unscrew the plug.
