I have a 86 c-27 that needs a new water muffler or a way to repair the old one. My water pump went out and over heated the exhaust hose and melted off part of the stub on the fiberglass muffler so I don't have quite enough tube on the input side to firmly clamp on the exhaust hose (1 1/2 inch ). I've looked for a duplicate but can't find anything exactly like it. What would be a good replacement or is there a way to put an extension on the current muffler?
