I replaced my leaking plywood and fiberglass holding tank cover with 1/2" grey PVC sheet from McMaster Carr. I took the old plywood cover out, traced a line on the PVC just larger than the plywood, and sawed a new PVC cover out with a jig saw. I stuck the new and old covers together with double stick tape, ran a router with a following blade around the edges of the plywood to make an exact PVC copy, then drilled the new screw holes through the old holes. I used the router again to round off the lower edge of the new cover. I installed a Beckson 4" cleanout (I have small arms) in the new cover. I bedded the new cover in GE silicone caulking made for plastics and screwed it down with new pan head screws. The clear Beckson deck plate lets me second guess my Scad holding tank level gauge.
I used the remainder ofthe PVC to make new cover plates for the batteries in the port locker.
Call the factory. They will also sell you a new cover saving you a lot of work but costing you a bit more.
