The John Deere RE538663 seawater pump can be replaced by the JMP JPR-S7635 seawater pump, also compatible with Sherwood P1735X and P1735-02 models used in marine engine cooling systems.
The JMP JPR-S7635 is designed as a reliable replacement pump for marine engines and ensures efficient seawater circulation through the cooling system, helping maintain proper operating temperature even during intensive use.
The John Deere RE538663 seawater pump and Sherwood P1735X / P1735-02 pumps are commonly installed on John Deere 6068 series marine engines and can be replaced by the JMP JPR-S7635 pump designed for professional marine applications.
Thanks to its robust construction and corrosion-resistant materials, the pump ensures reliable cooling performance, long service life and consistent operation in demanding marine environments.
NOTE 1:
The only differences between pump #JPR-S7635 and version JPR-S7633 is the angle of the mounting adapter plate. Please refer to the Dimensional Layout in the product images to view pump JPR-S7635 mounting adapter plate angle.
NOTE 2:
The Sherwood Impeller 27000, even though all the dimensions are the same, will not work in the JMP Marine pump since Sherwood makes their version with a threaded insert that is too thick and then bottoms out on the end of the shaft which prevents the complete impeller from fully seating in. If you use the Sherwood impeller you will have a clearance issue with the end cover and the impeller will heat up and melt. For the JMP Marine JPR-S Series pumps you must use impeller #7608K
