Has anyone ever had to service the exhaust dampers / flappers? ie: the things that keep water backing up the exhaust hose. I did not know there were any on Carvers until I read mention of them somewhere. I figured because they exhaust out the sides they had eliminated the need for them.

In any case mine are making an annoying racket. Sounds like a metal plate is loose and flopping around making a clinking, clanking noise. Has anyone ever seen or replaced these....0r possibly have pictures of what they look like. It sounds like the flappers are inside a separate short hose coupler that attaches to the fiberglass mufflers.

Many thanks for any knowledge you could pass along.
