I could use a confirmation that the Jabsco 6980-3100 pump is correct for a 12V71 from anyone who's rebuilt theirs. The DD # from the starboard pump cover plate is 23507972. After 37 years, I can't be certain the cover hasn't been scavenged from another unit along the way.

I think it's time for a port-side tune-up with a new cam, wear plate and end cover. I felt like the last new impeller I installed went in a bit too easily. I'm also running a tad bit higher water temp even after that new impeller and a clean HE.

Purty ain't it.

This cover plate looks a little strange (stamping), and the good side ain't much better than what's showing. Since the boat has ZF gears, the Allison stamping is unlikely not OEM; the other pump has only a DD stamp.
