I have been trying to think of a way to use a larger live-well I got from CTF member Fishstu. I wanted to make it removable, but have it look permanent. (No Hoses visible) I have been looking for thru-hull fittings that I could use in the floor and I wanted the fittings for the live-well to slide into them and be water tight.
I went to West Marine today and found a large brass thru hull for the drain and plastic one for pump that I could turn with my lathe to make them fit. Then added a groove for o-rings and they sealed perfectly. I have rubber stoppers to seal the fittings when not in use.
I found that 1"Charlotte PVC Pipe fit perfect in the drain fitting.
I used 3/4" Charlotte pvc on the pump fitting but had to turn it down a bit on the lathe to get it to fit.

Here is the live-well and thru hull setup.
