It looks like your CC is a 1987 and the live well is located in front of the transom approx 2 feet. If that is correct you can drill a hole in the bottom of your boat close to the transom and set up a scoop plum it on the inside with (brass) cut off valve and a 500 gal live well pump attached then run the hose from the live well pump to approx 2/3 of the way up the live well and drill hole in live well and attach I think ½” is the diameter of a 500 gal pump so you will need a ½ “ fitting that seals on both sides. You will need to drill a large 1 ½” drain line from approx 4 to 6” below the top of the tank in the back of the well and run it out the transom by cutting a hole in the bottom of the transom as low as possible (close to the drain plug height. You should use the thickened hose with brass fittings and two sea clamps on either side, just incase one breaks the other is still there.
