[C320-list] Water lift Muffler

[Mike Ott]

Tony,
I hate to tell you this but I think your solution won't last and I speak from 
experience.  I did the same repair and found that the original leak was just the 
beginning to future seam failure.  My fix lasted about a month and I had to pull 
the muffler again.  Since you already have the muffler out, I consider that the 
hard part, I would recommend glassing all along the flange area with fiberglass 
cloth before reinstalling. If your unfamiliar with this process let me know and 
I can walk you through it.

I would like to thank all that responded the information you shared helped 
alot.  


Went back to the boat today and traced the leak to the muffler.  I pulled the 
muffler. It came out much easier than  thought.   Did not even have to use my 
heat gun,

Found a 3 in hair line crack in the seem on the bottom edge. I can hardly 
believe water could seep through but I was able to watch water seep out.  My 
plan is to grind out the loose glass and fill with the West System.  Also plan 
to fill all the screw holes. If there is something out there that will work 
better than the west system please let me know.

I am going to lay down a piece of anti vibration matt that I got from Soundown,  
between the muffler and the pan.  


Will also see if I can find a hump hose as well.

Hopefully should have things all together by next weekend.  

Thanks

Tony

A lot of good guidance has been offered on the Muffler issue.
I would add two comments:
I removed the muffler( easy job).  Put some water in it. Using a bicycle pump 
pressurized 
it to 1 or 2 psi.  Water leaked out  2 screw holes and a bottom flange area. I 
cleaned/ glassed the 
problem areas (re-run the pressure test on the fix).. I had to glass closed one 
of the screw 
holes and move it closer to the edge. Then 
I installed a "hump hose" in the engine exhaust line to de-stress the load on 
the muffler.
good Luck,

Water in the engine pan could be from a few areas.  If it is coming from the 
muffler it should be easy to spot when the engine is running.  On our boat the 
water did run along the front of the muffler and down into the engine pan.  Most 


of the water should end up in the bilge area however. If it is a crack in either 


of the tubes of the muffler you may have some success trying to epoxy the area. 
If it is from the bottom less success.  If you are going to remove the muffler I 


would suggest that you cut the hose running to the intake tube from the mixing 
elbow so you don't break off the intake tube (from experience)  The hose is 
easily replaceable.  We had a shop reglass the bottom but it didn't last so we 
tried ourselves on two occasions before finally calling Catalina for a new one.  


If you are getting a new one be sure to send them the old muffler and not just 
pictures as they have several different molds with different intake angles. 
(again from
experience).  

All that being said if you can't see water exiting from the muffler the leak is 
elsewhere.  Check all engine hose connections and the hoses.  Check the 
connection from the overflow container.  Determine if it is water or 
antifreeze.  Good luck

Went to the boat today and started her up from her long winter nap. I dont think 


she wanted to get up because after I shut her down I found about 2 cups of water 


in the eng catch pan.  Looks like it is coming from the muffler.

I know this has been covered here before so I guess its my turn to R/R the 
muffler and explore my options and ask alot of questions should have paid more 
attention before.  What really kills me is how can it just go bad over teh 
winter.

How bad do they leak whne they go bad????  

I think one COA is to send mine to Catalina.  How long is the turn around time. 
Do they just fix mine or is it a new unit.  Any idea on current cost.

Is there anyone that knows where to go and get it fixed around Annapolis.

And I think I have seen where someone was able to by one for an aftermarket 
supplier.

Thanks
