Merc/kiekhaefer serial ID odd number id help

[AzogNewOrleans]

I need parts for an old Merc/Kiekhaefer 6 HP. The serial on the tag is 2083000. This number seems to be one number short according to the guide. Need to replace water pump parts. Thanks for any help, Dan.

The official mercury marine parts catalogue doesn't like that S/N Sorry!

When you say old, is it 1964-66 old?

That 2083000 # falls in the end of the 1964-66 range for 6hp Mercs. Possibly labeled a Merc 60?
