Our take
This suits a sailor who wants a 12V automatic bilge pump rated at 500 GPH, with an integrated outlet and external mounting feet that simplify installation. It is not the right choice for a boat that runs a different voltage or needs a different rated flow. Its main limit is fit: check the outlet and mounting space against your boat before you buy.
From our buying guide
Rule and Johnson both say their bilge pumps are not intended for damage control. Flow falls as the discharge head rises, and the length of the hose, its bends and any check valve reduce it further.
Check before you buy:
- The maker's own table shows the flow at head, since how much a pump loses depends on the model.
- An automatic pump also has a manual switch, which ABYC's voluntary 2005 standard calls for.
- You'll fuse it to the maker's figure.
