[C320-list] Aqualift Muffler

[Chris Burti]

Scott,
Your water tank ‘leak’ is most likely the inspection port which will leak when you fill the tank… a couple of wraps of Teflon tape or the o ring from   plumbing dept will help.

Thanks,

FWIW. Update on my muffler.
I must have had a loose hose fitting.  Took off the muffler. (wasn't "that" easy) Tried several ways to find a leak and could not find one.  Did not do a thing to it.  Re-installed it and ran for 7 hours one day then ran it for 9 hours couple of days later and no leaks.  (Went to Ocracoke on the NC Outer Banks for 300th Anniversary of Black Beard's Death)
Also had minimal dripping with re-packed stuffing tube. (After several adjustments)
Had a dry bilge when we started.  Then... I filled to forward water tank at the marina and I later heard the bilge pump go off.  Dang it, have a leak in the forward water tank/line someplace.  Two steps forward, one step back.  This should be an easy one at least.   Just have to find it. 
Thanks to all the help working that Muffler issue.

Yup, as Doug says you can safely remove the muffler without worrying about
sinking your boat.  Closing the intake seacock isn’t really necessary,
 but without the muffler installed you will have no reason to have it open.

Now about that muffler.  We went through this whole thing two years ago.
We discovered the leak in August and I 'repaired' it.  The muffler design
is basically a box with a nested bottom plate.  The seam between the box
and the nested plate is where the muffler fails.  The repairs that can be
made are almost always a delay tactic.  Very few folks have made
successful long term repairs.  We limped through to haul out and then
ordered a new muffler.

In order to get a new muffler you will need to send back the old one.
Based on my experience with another vendor I would have to recommend
calling Catalina in Florida or Vetus for a replacement.  Expect this
process to take a while, and also expect to fill the old screw holes and
drill new holes.

If your muffler is leaking enough to fill the tray beneath the engine, then
you will also have water trapped underneath the galley drawers so don't
forget to get that with the shop vac.  If you haven’t gotten to that stage
of the leaking process...it probably will get there soon.

Good luck
