Jim,
For the bilge pump issue, I was able to find an old, but unused, Rule 27D on eBay. That clipped into the existing strainer bases in the bilge so I did not have to unscrew and replace the strainer base.
For the cabin drain hole issue. I bought some thin wall (0.014 inch) 1/2 inch brass tubing. I will drill two holes through the aft wall of the cabin at the floor level and seal the brass tube to the wall with 3M 4200 adhesive at both ends. That should provide better protection for the core of the cabin wall than trying to line the hole with epoxy.
