Don, I didn't know
I really need to get down to Liberty more often. I will take another look at the flooring under the toilet. I seem to recall that the flooring material was molded, with a shelf a couple inches above the sole of the head. Kind of like the flooring under the galley sink area. I need to see how one accesses the wooden panel under the molded floor (plastic, fiberglass, who knows?).To answer the others, I went out and bought a replacement toilet on the spur of the moment. It was price that drove me, not research. My wife says that I have to be one of the cheapest guys around.Anyway, I bought a Jabsco Manual Marine Toilet. I ended up saving about 40%, being on sale and using a Boat US discount. Afterwards, I caught a few comments here on HOW that really trashed the Jabsco. We shall see.The original toilet worked OK, and it may have been an original on this 1981 H33, I just don't know. The only problem I was having was that if I left the fresh water valve on and went sailing, there was a good possibility the toilet would fill on it's own, and overflow.I know, I know...install a vented loop. I just downloaded installation instructions on the Jabsco from their web site, and the instructions look excellent.Looks like the project for next weekend. Or maybe get in another day of sailing before it gets too cold.Cheers,Ken Palmer, S/V LibertyRochester, NY
