and replace the impeller as necessary. To gain access to the impeller,
the pump must be disassembled from the bilge pump grate. Simply
push the tabs of the grate inward towards the bilge pump, while
simultaneously pulling up on the bilge pump. This locking mechanism
functions much like a quick disconnect clip. If the fuse for your bilge
pump “blows”, be sure to investigate why the bilge pump was drawing
too much power. Likely causes of bilge pump malfunction are debris
in the impeller, bad impeller, debris in the fl oat switch, bad motor, or
short circuit.
