I have a Tracker Panfish 17. The aerator pump will not fill the livewell without backing up. I have checked the livewell connections ( and some were not as tight as they could be.) I thought the pump should run clockwise, but the manufacturer said it should run counterclockwise. I will change this .Anyone have any other suggestions. How about increasing from a 500 to a 800 gph aerator and making sure all connections are tight. Thanks for any help.
