good for the price
by Jeffrey from Ontario, New York on July 07, 2015
It was an Attwood replacement for the previous model Attwood I had. I would have gave it 5 stars if the mounting holes were located the same as the original model.

Sahara, keeping me dry.
by Robert from Laurel, Delaware on March 04, 2012
I purchased this product as a replacement for the original Attwood bilge pump that was installed by the boat manufacturer. The old,original pump was 12years old. installation instructions for the Sahara were easy to follow and complete. The new pump works great, my decks are perfectly dry now and the bilge area is kept water free. Thanks.

bilge pump
by James from Mansfield, Ohio on February 05, 2012
One of the better small pumps I have seen and tried. As with all the things nowdays, it seems a little expensive but considering all the others, I settled on this one. It pumps well, and the auto feature is worth the extra price, that way, you do not have to install a extra float which takes up more space. For a small section of a boat, this is fine. Use a bigger one back in the transom though, where most water runs to. If you spring a leak, you want something bigger than this one.

Perfect match for my 2013 Boston Whaler
by John from Dekalb, Illinois on February 23, 2016
This pump is a perfect match for the one in my 2013 Boston Whaler. I like the manual test lever for the float switch. The float switch in my original pump failed after 2.5 years but the pump still worked on manual. Now I know how to test it.

Love This Pump!
by Patrick from Beaufort, South Carolina on August 16, 2014
It was easy to install and works like a charm. I purchased it to replace a Rule-Mate that had quit working on automatic. Presumably, the "high Tech" switch failed but how and why and, most importantly, there is no way to remedy the problem. I was delighted and relieved to find the Atwood has a float switch when I received it. If it fails on automatic, I'm pretty sure it will be a simple thing to clear any debris that might be fouling the switch so it will work again. Of course, if I keep the bilge clean, there should be no reason for the float switch to fail.

GOOD for the price
by ROY from MARMET, West Virginia on September 14, 2013
This is the second on of this model I have had , the first was a great pump. I gave it a 4 out of 5 only because it had trouble handling bleach water we cleaned the boat deck with . This caused the plastic to have problems crack open then water killed it .....

Will gas in water affect it?

Will a dishwasing detergent such as "Joy" in the water affect it?
