Locked battery/ bilge pump box
I have a WM RIB 10' and a Nissan 9.8 electric start, it takes a small lawn tractor battery to start, how ever I use a regular size battery box. I epoxied a piece of 1/2 plywood and sealed the entire plywood with epoxy into the box creating a space for my battery. I also drilled 1/2 holes in the edges of the other compartment and installed my automatic bilge pump, and plumed it thru the transom about 4" from the top. Now so the battery and box don't walk away I've bolted the box thru the transom and used a strip of 2x 1/4 aluminum as a back up inside the box. Then I cut strips of aluminum and drilled and glued to the end edges of the box and installed 2 master locks, sounds like a lot, but my pump and battery have been with me now for 2 years
