What I see in the center console; a 5 1/2" hole (starboard) into which are control cables, wiring, drain tube for fish box, and pre-wired harness routed forward for a trolling motor. What I have not found is a tube or pathway to use in routing transducer cable. I say this because at the aft end along the center line control cables exit and wiring harness branches off to join at the Motor. I have tried to find a common tube, to no avail. If there is one it must end out of sight. I can't speak for the manufacturer, but, it would not be too wild a guess that they run what goes in the hole before the boat is rigged. Looking at the excess of cable located at the Motor Bracket I kind a think it would fit a 20' or a 19' Model.Should be a rigging tube under the deck somewhere.
How did they bring the engine wire harness to the helm
