This Johnson Pump bilge pump is rated at 1000 gph. The housing is thermoplastic that resists impact, chemicals and fuel, and the shaft is 316 stainless steel with corrosion resistant hardware. It comes with a removable check valve and two externally threaded Dura-Port discharge ports, one straight and one at 90 degrees. The motor cartridges can be replaced or upgraded. It is made in the USA with a 3 year warranty.
Our take
The replaceable and upgradable motor cartridge is the practical feature of this 1000 gph pump: a worn motor can be swapped without replacing the housing. The included check valve and choice of straight or 90 degree port help with the plumbing.
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.
