I own a 1992 Catalina 28 sailboat in which the hot water heater was leaking. It is located in the port side cockpit locker. I basically disassembled it in order to get it out! Now, I’m wondering how to get the new one in ! I’ve climbed and went over every area of the head, port side of the Engine compartment and aft section of the boat and it seems as though it’s all encased in fiberglass! I was informed by a local distributor of Catalina sailboats that I had to take out the wall of the head in order to get the heater back in. But, as I stated above I tried this and it seems that the only way to put it back in is to cut out a portion of the fiberglass?! Please, is there anyone out there with this experience?!
