[C320-list] Dry aqua muffler

[GREG SUTTON]

Thanks Warren, I have tried all those fixes on my boat also with no success. 
I was concerned that part of the muffler is plugged so it's not allowing a free flow of water through out it.  I am hoping that someone would respond with a cross section or a description of how the muffler works to add in the problem's diagnosis.  If I make the effort to remove it, can I get it apart or is it sealed?
