*G18082X uses Sherwood impeller 18000 (#8350-01K) having a spline drive with 14 splines. The G2902X uses Sherwood impeller 29000 (#8359-01K) having a spline drive with 10 splines. You can use complete pump assembly #JPR-CT1800R to replace G18082X but you cannot use the internal parts (JSK0139, JSM0139) of this replacement pump to service the older pump version of G18082X. If servicing this older model G18082X you can use Minor Kit #JSM0139 but you will also have to purchase impeller #8350-01K which is the impeller having 14 spline drive insert.

*The parts of kit JSK0139 and JSM0139 can be used to service pump(s) JPR-CT1800R and Sherwood models G2902X, G2906X. Both sherwood models use the same internal parts and so Major Kit #JSK0139 and Minor Kit #JSM0139 can be used for both pump models; however the drive gears (not part of the minor or major kit) are not the same . . . its important to note that G2902(X), which is JMP Marine pump #JPR-CT1800R, uses drive gear p/n 22789 (has 40 teeth) while G2906X uses drive gear p/n 25191 (has 36 teeth) and is why you cannot use the complete pump assembly #JPR-CT1800R as a direct replacement for G2906X. To use pump JPR-CT1800R to replace G2906X you would have to remove the drive gear on pump and install your existing drive gear from your G2906X having 36 teeth.
