Did you try epoxy? I have used the two part putty to repair a leaking fuel tank connection.

Has anyone repaired the aqualift muffler where the drain fitting screws into
the side of the muffler just above the bottom?  On WindSwept mine developed
an intermittent small leak and I decided to replace the fitting.  When I
took the fitting out the male threads were badly corroded.  Seemed like an
easy fix but when I screwed in a new fitting it became obvious that the
female threads were in bad shape too.  So far I have not be able to get a
leak free seal even with the use of a generous amount of Teflon tape.  The
internal female threads are so bad that the fitting doesn't engage until the
fitting is almost bottomed out.  I am looking for a fix that I can make
without having to replace the muffler or take it out of the boat.  I would
like to avoid removing it if possible.  Any suggestions?
