A livewell/baitwell pump includes a replaceable cartridge for arranging in a pump cartridge body of a pump cartridge assembly. The replaceable cartridge is rotatably coupled to the pump cartridge body and locked in place by a pre-loaded locking lever that securely engages a locking edge of the pump cartridge body and holds the replaceable cartridge therein. The pre-loaded locking lever is spring-loaded and pivotally arranged on the replaceable cartridge to snap into place and lock the replaceable cartridge when the locking lever is rotated passed the locking edge, so that the replaceable cartridge may be installed in the cartridge body using one hand. In operation, when the replaceable cartridge is rotated into the pump-cartridge body to a desired locking position, the pre-loaded locking lever engages the locking edge of the pump cartridge body. The locking edge is formed on an annular rim on the pump cartridge body as a raised edge. Moreover, the pre-loaded locking lever is pressed inwardly, then twisted in order to remove the replaceable cartridge from the pump cartridge body, so that the replaceable cartridge may be removed from the cartridge body using one hand. The pre-loaded locking lever includes a bias member, such as a spring or other suitable elastic member or material, for continuously urging the pre-loaded locking lever against the replaceable cartridge.

The invention claimed is: 1. A pump having a replaceable cartridge for arranging in a pump cartridge body that forms part of a pump cartridge assembly, the pump comprising: a replaceable cartridge configured with one or more protruding members and a pre-loaded locking lever having a locking lever feature; a pump cartridge body configured with one or more corresponding threads and a locking edge; the replaceable cartridge being rotatably coupled to the pump cartridge body by rotating the replaceable cartridge in the pump cartridge body about a ¼ turn to a desired locking position so that the one or more protruding members rotationally couple with the one or more corresponding threads for grabbing, drawing and seating the replaceable cartridge in relation to the pump cartridge body, and so that the locking lever feature of the pre-loaded locking lever rotates past and securely engages the locking edge of the pump cartridge body and locks the replaceable cartridge in relation to the pump cartridge body. 2. A pump according to claim 1, wherein the pre-loaded locking lever is spring-loaded and pivotally arranged on the replaceable cartridge to snap into place and lock the replaceable cartridge when the locking lever is rotated past the locking edge, so that the replaceable cartridge may be installed in the cartridge body using one hand. 3. A pump according to claim 1, wherein the pre-loaded locking lever is first pressed inwardly, then twisted in order to remove the replaceable cartridge from the pump cartridge body, so that the replaceable cartridge may be removed from the pump cartridge body using one hand. 4. A pump according to claim 1, wherein the pre-loaded locking lever has a housing having lever pivot points and contains a spring. 5. A pump according to claim 1, wherein the pre-loaded locking lever includes a bias member, such as a spring or other suitable elastic member or material, for continuously urging the pre-loaded locking lever against the replaceable cartridge. 6. A pump according to claim 1, wherein the locking edge is formed on an annular rim on the pump cartridge body as a raised edge. 7. A pump according to claim 1, wherein the pre-loaded locking lever makes an audible latch verification sound when the pre-loaded locking lever is coupled to the locking edge as the replaceable cartridge is seated and securely fastened in the pump cartridge body, allowing the user to easily secure the replaceable cartridge in areas not readily accessible and in some cases not visible. 8. A pump according to claim 1, wherein the replaceable cartridge has a rubber type over-mold that allows for a firm grip in a wet environment which enhances the removal and installation of the replaceable cartridge. 9. A pump according to claim 1, wherein the pump is a livewell/baitwell pump. 10. A method comprising: inserting a replaceable cartridge configured with one or more protruding members and a pre-loaded locking lever having a locking lever feature into a pump cartridge body configured with one or more corresponding threads and a locking edge; and rotating the replaceable cartridge in the pump cartridge body about a ¼ turn to a desired locking position so that the one or more protruding members rotationally couples with the one or more corresponding threads for grabbing, drawing and seating the replaceable cartridge in relation to the pump cartridge body, and so that the locking lever feature of the pre-loaded locking lever rotates past and securely engages the locking edge of the pump cartridge body and locks the replaceable cartridge in relation to the pump cartridge body. 11. A method according to claim 10, wherein the pre-loaded locking lever is spring-loaded and pivotally arranged on the replaceable cartridge to snap into place and lock the replaceable cartridge when the locking lever is rotated past the locking edge, so that the replaceable cartridge may be installed in the pump cartridge body using one hand. 12. A method according to claim 10, wherein the pre-loaded locking lever is first pressed inwardly, then twisted in order to remove the replaceable cartridge from the pump cartridge body, so that the replaceable cartridge may be removed from the pump cartridge body using one hand. 13. A method according to claim 10, wherein the pre-loaded locking lever has a housing having lever pivot points and contains a spring. 14. A method according to claim 10, wherein the pre-loaded locking lever includes a bias member, such as a spring or other suitable elastic member or material, for continuously urging the pre-loaded locking lever against the replaceable cartridge. 15. A method according to claim 10, wherein the locking edge is formed on an annular rim on the pump cartridge body as a raised edge. 16. A method according to claim 10, wherein the pre-loaded locking lever makes an audible latch verification sound when the pre-loaded locking lever is coupled to the locking edge as the replaceable cartridge is seated and securely fastened in the pump cartridge body, allowing the user to easily secure the replaceable cartridge in areas not readily accessible and in some cases not visible. 17. A method according to claim 10, wherein the replaceable cartridge has a rubber type over-mold that allows for a firm grip in a wet environment which enhances the removal and installation of the replaceable cartridge. 18. A method according to claim 10, wherein the pump is a livewell/baitwell pump.
