I'll bet any money the source of your leak is the packing gland, located where the prop shaft exits the hull. Needs tightening, surprised Catalinas' reps didn't catch it. 
Additionally, always, always, always have your bilge pump on auto, unless your boat is on dry land. I've never (boating since the '60's) heard of anyone doing otherwise.
