Replacing Pumps on Nitro 482

[CatchKissRelease1]

This is my pre-Spring project. These are the before pictures. Starting with the aerator pump fitting into the lower part of the live well. This is a pretty easy task. Cumbersome part is removing the oil tank and batteries in order to get to the panel.
2nd photo is another aerator pump, and the 3rd is the bilge. Last two enhanced with part number of 1st pump.
