I recently bought a 98 pro team 175 bass tracker. I need to reseal my thru hull connenction for the live well drain. Problem is it is located under the aerator and recirculator. But I cannot seem to remove the pump to get to the nut on the thru hull. The pump and recirculator is connceted to a thin metall bracket that is riveted to the the hull. Any ideas on how to remove the pump and recirculator. I have removed the hoses and have tried to twist the aerator pump but don't want to break it. I do not see any screws. Any help would be appreciated. Thanks
