We just pulled the raw water pumps on my 1976 GB 36, which appear to be the original 1976 Sherwood pumps for the marinized John Deere 404 twins. Boat is new to me this year, and appears that the seals were leaking for quite a while and significant corrosion. Ideal would be to replace with new raw water pumps, but finding it a challenge to locate the same Sherwood pump new. Anyone with an older GB with the John Deere 404 engines replace the raw water pumps with new Sherwood pumps that are the same, rather than rebuild? If so, what was the source for the new Sherwood pumps? Or is the only option another rebuild of the original pump? Thanks in advance for the shared wisdom and experience.
