Does their aerator system drain out the overflow/vent holes as opposed to the fill holes on bottom of boat? How do you like that?
Yes if the bag over fills it will drain out the exit hole on the side of the boat. I usually just keep them on fill until I see the water coming out and know its time to shut off the pumps.
