The Attwood Sahara MK2 S800 (5509-7) is an automatic electric bilge pump rated at 800 GPH on 24V. Its patented X-Air impeller pushes trapped air out of the pump and pipework, which is how the maker targets air-locks. The outlet takes 3/4 inch or 1 inch hose, and SteadySwitch reduces cycling to extend pump life. The universal mounting pattern is meant to make replacement simple, and the cartridge can be serviced with one hand.
Our take
The patented X-Air impeller is the feature to note on this 800 GPH pump: the maker says it pushes trapped air out of the pump and pipework, which targets air-locks. SteadySwitch is there to reduce cycling and extend pump life.
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.
