So I'm in the process of upgrading the front depth finder on my 203 from an old Humminbird in the stock hole to a newer HB 899. Think I'm leaning more towards a bracket like deck-it or precision-sonar mount around the recessed trolling tray vs a ram mount on the deck. Anybody have this setup already and have any recommendations. Also what to fill the old hole with. Anybody made a tool holder that sits in the old hole or a drop in storage box? Or maybe bolt gimble bracket to a cover plate.
