2002 super air ballast pumps

Are these factory pump rebuildable? Can you change the impeller? Also does anyone have a part number for the fresh water impeller? The ballast pumps run but dont pump very much. Does anyone separate the controls for front pump and rear pumps? Any ideas on how.

You do not have impellers in your ballast pumps. They are aerator pumps. You may have priming problems or your pumps aren't working and you are just getting filled by the scupper thru hull.

So as long as they run then they should pump? They have always worked before but this time they didn't.
