[C320-list] Hump Hose

[Jeff Smith]

Joe,

Thanks. I have the Perkins M30. My exhaust hose is shot, so I ordered the hump hose to replace it. Of course, it is about 3” too short, so I am interested to know if it matters which side of the system the jump hose is installed.

Thanks,
Jeff Smith

Here is my question (that will turn into four). Do I connect the silicon hose directly to the muffler? Or do I connect it to the mixing elbow? Or do I, as I saw one person do, have 2" exhaust hose connected with fiberglass on either side of the hump?

Also, Catalina Direct sent approximately 8" of fiberglass rod to use as a connector, which also made me second-guess myself. Of course, I am at the boat (4 hours from home), so I can't access my email folder where I saved all of the exhaust threads. I did search the Association, but did not see anyone address this specific question.
