Water lift Muffler

[Jon Schneider]

Good to know.  I'm hoping I don't need to replace mine this season (at least).

I had a similar problem on my '88 this year regarding the leaking hump hose. 

In my case, I came up with the clever idea to replace the standard hose clamps with some of those solid steel band style hose clamps thinking more torque was the solution to this leak.   It was but indirectly -- I ended up torquing the clamps so hard around the hump hose that I  crushed the tube that went into the muffler.  Maybe as a result of the crushing, I was able to pull/rotate the tube cleanly, as one piece, out of the muffler.  This fiberglass tube was glued or fiberglassed into the box as a part of the standard muffler manufacturing process.  This made the repair easy and I had the shipyard epoxy/balloon a standard pipe type fitting with pipe thread (down) barb side (up) very cleanly back into the hole.  Althought I wouldn't recommend this as the "plan a" over the rebuilds noted, it may be a decent interim step to try prior to ordering a new muffler.  I'm up to over 50 hours since the repair with zero signs of cracking at the fitting/muffler joint.
