Rebuild Sherwood or a new Oberdorfer raw water pump? That's a good question. Sure a new Oberdorfer would be nice and changing the impeller would be a lot easier, but all at a hefty price. I need to replace the two lip seals because the pump is weeping. But before I do anything, as always I look to the wisdom of those that have had a need to look into this. What say you oh wise ones?

Not a wise one but I did sleep in a Holiday Inn Express once! Be prepared to change the bearings as well as the seals.. If yours has bushings instead of bearings, be ready for new bushings..

I was faced with the same problem last year on my little M 12 Universal diesel. If I remember correctly a total rebuild kit for the Sherwood was about $80.00. I went the Oberdorfer route for about $215 from Cardinal Pump out of St Louis, MO. I am very happy with the Oberdorfer.
JTCB (Just to circle back). I bought a new Oberdorfer pump. N202M-07 Nice! Install this week.
I rebuilt my Oberdorfer N202M-15 once. Total cost in parts was $178, and it took me a couple of hours of inventive machinining to dissasemble (the graphite bushings and the seals were a pain) and to rebuild. About 4 years later it was leaking again
. I then purchased TWO N202M-15 pumps (one spare) from Depco Pump in Clearwater, FL for about $220 each.
