Im curious to see if someone can give me a good idea for running some wires that will come from the rub rail and need to go down through the deck to a switch panel. The deck is honeycomb material and so far I have been unable to find a rubber grommet large enough (1/2" panel thickness) to fit the job. Any other ideas of how to keep water out and not have a mess of wires exposed? It'll be only a short run of about 2 to 3 inches from rail to deck. Would also like to do my fuel line this way from under the rear deck out the top and to the outboard. Thanks!
