[C320-list] Leaking Muffler

[pat reynolds]

If you can get it off without damage your repair might hold.  I broke off the 
entry nipple in twisting the hose.  Catalina suggested I just send them a photo 
which I did but the muffler they sent had the angle wrong and a larger lip which 
I had to grind down to make fit..  I had it a year when it started to leak badly 
under the bottom and the repair shop said it was poorly laid up.  I would 
strongly advise that you box up the old muffler and send it to them.  Apparently 
this is something they do not keep in stock and make anew when requested.

While doing my pre-lunch engine check on the Yanmar, I noticed water building up 

around the shaft stuffing box. Tracking it back to the muffler flange, I was 
hoping beyond hope that all I had was loose exhaust hose clamps, I tighten 
everything ... no luck.  Mopping up the water I noticed seepage under the fwd 
flange of the muffler.   Pulling that sucker appears to be the only answer.  
Anybody have this fun before?  Any nice ease hints? I think my approach at this 
point would be to grind the area, Marine-Tex the seam, and then glass over 
with some fiberglass mat or cloth.  Pulling the exhaust hose from the wet elbow 
to the input nipple on the muffler looks like it is going to be fun (almost as 
much fun as pulling it back on).  Good thing I have a couple of weeks until my 
launch date.  Would welcome some opinions / advice.
