I am about to mount 2 fishfinders on the front deck a couple inches from the bow panel and would like to run the cables up thru the deck with the cable pass thru but it is too far forward to reach from inside the front compartment. Looking through the hole in the bow panel where the old depth finder was it seems there is a wall directly under the bottom of the panel. Is there access under that part of the front deck? I'm trying to get an idea before I pull the bow panel off....
