    Based on your pics, I think the area where the holes for screws is for the pump shoe, not where your ride plate attaches? You can get new re-enforce screw inserts for the shoe (tap inserts) even some that have in-hull strengthen plates that can be installed inside the hull.

    Agreed! I can't find the brackets online but I'm sure Jerry sells them!

    That 03 never had the factory bracket recall performed. The old style pump shoe brackets pulled thru the hull and it probably sunk. You will need to install a tunnel reinforcement and updated brackets, along with repair to the tunnel. That keel will need repaired also.
