    I have two 1999 Cummins 6CTA 8.3 M3 engines. Serial numbers 45889663 and 45889973. I want to replace both Sherwood raw water pumps with SMX pumps but I’m confused as to which model to order. The port pump is stamped with P1730F WHC while the starboard is stamped with P1727A GFD. Do I need one SMX-1727 and one SMX-1730? I would expect both engines would have the same pump. Thanks!
