I mounted the bilge pump much farther forward than the original installation. I mounted in the lowest part of the hull, near where the battery was mounted, by the driver's feet. I layered up a bunch of filled epoxy and drilled for screws. The epoxy let me secure everything without going into the hull and avoiding needing a wood mounting piece. Worked great.
On the starboard primary stringer, there is a 1" pipe that I'm planning to use for engine wiring. There are wood supports on each end cut with a weep passage on the bottom and I will wrap a strip of glass over these points and fill the gap with silicone after the epoxy "tacks" set up tomorrow.
