Leaks through layers of laminate scare the be-jesus out me. Wonder if it's freeze damage? I think it's going to take a fiberglass guy to look at it. Maybe they can haul it out, drill bazillions of holes into the area, dry it out and then squirt all sorts of epoxy resin into that area and that would just be a patch.

I am curious and tempted to try drilling a small hole into that platform that the muffler is screwed onto just to see what happens - if it is solid or hollow and if water comes out. What do you think? Dumb idea?

That would yield some valuable information. I'm guessing it would yield some increase in your heart rate while the hole is being drilled though. You'll need a plan to stop the leak if you strike a gusher.
