I haven't tried the liquid tape but the heat shrink works great. I used a bunch of it while installing the trolling motors. Your gonna need an avenue to run the antenna wires/cables for the VHF and GPS thru the console. I drilled as small a hole as I could and used a small chrome vent and filled it with a silicone caulk. One mistake I made was not straightening the cable out prior to connecting and caulking. Now I need to cut and reconnect, it's way too long anyway and the coil under the console needs to be cleaned up, get's in the way, and there is allready not enough room under there.
Anyone have any experiance with cutting these cables and attaching a new end connector? Can't be that hard, Right?
