Product Description
johnson_pumps Bilge pump cleaning and maintenance no longer call for complete disassembly. A Cartridge Bilge Pump from Johnson Pumps can be removed for cleaning or replacement without the use of a single tool. Just lift the locking tab on top, give the cartridge a twist, and pull it out; that's all there is to it. The cartridge contains an all-in-one motor/impeller unit with no loose parts.

The Johnson Cartridge Pump uses remarkably little electricity for the amount of water it pumps. The improved, efficient motor also provides increased service life, thanks in part to an ingenious solution which circulates the discharge water around the motor for cooling.

The improved design of the 500 GPH cartridge pump includes easy-to-install Dura-Port discharge ports to eliminate stress cracking caused by over-tightened hose clamps. This pump comes with both a straight and a 90° smooth elbow Dura-Port as well as a removable check valve.

                Direct replacement for an older existing pump in a difficult to reach spot, so installation was a snap instead of a chore.

                    Hello Lou,

                    The manufacturer does not give the maximum pressure of the Johnson 500 GPH Bilge Pump. They do indicate that the pump is strong enough to lift the water from the bilge up to 3 feet above the pump.

                    Thank you,
                    Steve

                • Q:

                  This pump looks similar to the one on my 1998 Bayliner 2050SE Capri. The pump on my Capri is red and named "Johnson Pump". It is a 500GPH pump with a very similar profile. Is the Mayfair a replacement pump?

                    A:

                    This would be an upgrade from your 500gph pump as this on is a 720gph, and would require complete replacement.

                • Q:

                  WILL THIS BILGE PUMP REPLACE MY ORIGINAL 1986 MASTERCRAFT MAYFAIR JETTISON MODEL 1225 BILGE PUMP. IF YOU HAVE ANOTHER BILGE PUMP THAT IS MORE COMPATIBLE AS A REPLACEMENT I WOULD PREFER TO PURCHASE THE MORE COMPATIBLE PUMP.

                    A:

                    I do apologize but we do not have a direct replacement for your current bilge pump. This pump will work but you might have to drill new holes.
