I am selling my 2002 Catalina 28 MKII. Don't worry, I plan to buy a bigger one. Anyway the buyer's survey says that the exhaust hose is dry rotted and dripping where it exits the hull and should be replaced. I looked at it and agree that at least the terminal end should be replaced. Looking to replace the entire hose, the terminal end is easy to get to through the rear hatch, however the end that come out of the muffler is hidden within the fiberglass wall between the head and aft cabin. It does not look like you can get to it without cutting fiberglass. Has anyone dealt with this and how did you replace the entire hose?
