In 2012 I purchased a 1999 Harbercraft 1625 (and I love it) The boat came with a Humminbird 200DX depth sounder/fish finder. The Humminbird has been a real P.O.S. from the very start; virtually useless in salt water over 200'. I have just purchased a little Lowrance depth sounder/fishfinder and want to install it this weekend. The problem is the connector on the end of the cable that connects the transponder to the unit is too large to fit through the drain hole in the rear transom. I would prefer not to run the cable over the top of the transom because it would be exposed to possible damage there so I have a couple of options. #1 is to cut the connector off (at the display end) and solder the wires back together once cable is installed. I'll bet however that would invalidate the warrenty (and possibly affect the performance negatively). # 2 is to increase the size of the existing hole in the rear transom so the connector will pass through it. This option would require a new liner for the hole and I have no idea where one could find one of those; maybe Harbour Chandler, they have pretty much everything there. Any advice would be very much appreciated. Cheers; Twogone
