35 Bertram Water Tank
What a great job you are doing, so complete! I have a '76 35' and my water tank has given up the ghost. It's aluminum, I've been patching holes for awhile but too many now. I was think of cutting a large piece of the plywood out, on top of the tank, then cutting the top off, cutting the baffles out, and installing a bag right in the tank. It sounds like you took your whole tank out.
Can you tell me what kind of a job that was? Did you cut the plywood out so you could see the entire tank? Did you take the tank out in pieces?
