If you can handle....
a fiberglass job...George, try to search the archives, there's plenty of information in there on this issue.I had the same problem when we bought our C30. A lot of people have repaired their muffler box. I opted to replace it with a Vetus watermuffler, which is much smaller in size and quieter (I feel). The added space in the engine compartment was use to install a dedicated starting battery. I must say I am extremely happy with the set-up. We've stopped being nervous about draining our house batteries.Peace of mind means more fun.Ghislain C30TRBS 1987 #4708Emilie-Jolie
