Claude, Thanks for sharing the amazingly detailed set of compression post pictures. I recall seeing this early after joining and not fully comprehending what was involved. It is now saved in my "Don't Leave Home Without It" file. Don, thanks for the option of making another cut. Off to the boat again in minute and taking the saw just in case I run out of wiggle. BTW, nice looking tank. Kloudie, I'll try removing those extra screws first and pull the wall plate out. FYI, all this started when I had to remove a section of wet, rotted sole under the water heater. Refinished the aft settee at home and decided to pull this one to do the same and make it easier to refinish the sole before reinstalling water heater. Thanks, again.
