I’m in the process of changing all my waste hoses.Some are straight forward but the ones to the head and the deck plate seem tough to access. Boat is a 2003 38 open.Any tips appreciated.Bill

Not on a Tiara, but I helped a friend replace a waste line on his boat. He got a double end barbed hose fitting and attached the new waste line to the old one. I believe he used some adhesive on the barb since he couldn't put clamps on it. Then, while I gently pulled from the engine room, he was gently feeding the new line from the head. This allowed for both removal and installation at the same time.

Perhaps something like that would help?

For the one to the deck fitting, I’m not sure how you’d do it without removing the deck fitting itself. Use the hose barb method mentioned above and pull it through.
