PLEASE NOTE: Minor Kit #JSM0139 is fully compatible with OEM; JMP Marine uses the highest grade of materials in manufacturing all their parts & components which ensures the longest-lasting performance product for the customer.
*The parts of kit JSM0139 can be used to service pump(s) JPR-CT1800R and Sherwood models G2902X and G2906X. Both Sherwood models use the same internal parts and so 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 . . . it's important to note that the 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 the pump and install your existing drive gear from your G2906X having 36 teeth.
