The only single bank ProSport systems are 6amps. That is pretty small compared to the total capacity of your bank. ~1%. I can't explain it but maybe that's part of the problem. Sometimes certain switching power supplys need a load for them to work properly. A large enough bank and a small enough charger may act the same way.
Did you wire it directly to the battery terminals? Or did you go to a nearby bus bar or previous feeder wire? I would also like to know what a Multimeter reads at the charger terminals and what the meter reads at the battery terminals (if they aren't the same). I'm wondering if maybe the charger isn't sensing the same voltage as the boat's meter and the battery.
