I replaced an old attwater pump that worked for 15 years with this one. The mounting is different so had to start from scratch. Pump turns on but won't cut off. After a whole day of fiddling with it and remounting it 5 times, I figured out that the float is not heavy enough to turn off the pump switch when all the water is gone. It would probably work on a moving boat where the vibration of the boat would get it to work, but at dock or on the trailer the pump would run until the battery goes dead. Bad design

      Comments about Sahara Automatic Bilge Pumps:

      This was a direct replacement. Although the first one I purchased to replace the dead one also tripped the breaker, West Marine swapped it out with no questions asked. This is a back up pump used in the bow area, so it is not important that it remove huge amounts of water.

        Comments about Sahara Automatic Bilge Pumps:

        This pump works well, when it's working. Unfortunately, the float switch was hitting the top of the chamber before the switch was activated. So it wouldn't activate, even when completely submerged. Good design, but poor construction made this pump a failure. Since West Marine only has a few low-profile pumps I exchanged the dead one for the same model. Checked the new float switch before installing and it appears to be OK.

        Service and delivery comments:

        West Marine's return policy is stellar. Returns and exchanges are always easy and courteous. Thanks WM!

            I went through 3 of these in less than 7 months. This all in one pump needs more perfection, it does not take much for this pump to stick, therefore your bilge is filling with shower water...NOT GOOD.

              Pump looked competent in design. Easy to install in 19 foot boat with no scuppers.
              One heavy rainstorm which required continuous operation caused motor to burn out
              after less than 2 months of install. Signs of slight corrosion at impeller shaft. Would not
              use again and would not recommend.

                Bought because store was out of automatic Rule pumps. This pump was not reliable, the float jammed on several occasions both in the up and down position. The unit was mounted and wired correctly.

                Comments about Sahara Automatic Bilge Pumps:

                I hooked it up to replace a similar Attwood 500gph bilge pump which had been working well until the motor burned out when it got clogged. The new one, which worked perfectly at first, stopped working after 2 days and my bilge filled with water necessitating manual bailing. I'm not sure why it stopped, it's just spinning at 1/10 the full velocity and pumping capacity is ZERO, in spite of good battery voltage > 12V. I will not be replacing this with the same unit.

                  My Sahara 1100 worked great, FOR ONE YEAR! After one year, the auto function no longer works, just the manual. The float is making a connection, but nothing happens. I will replace it with any pump other than another one of these. This product is a poor design if it only last a year. Don't install on a boat that is put in the environment of the ocean!

                  No amateur at installing these, this one refuses to shut off. Poor design on float switch. Even worse customer service. I called Attwood 3 times, left 3 messages with no return call.
