I am currently in Aruba doing an overhaul of my Columbia 36 with
Atomic IV engine. We're almost ready to depart to Colombia.
Unfortunately there's one puzzle I'm so far unable to solve. I'm
pretty sure I have an Oberdorfer 202M-3, although I can't check the
part number anywhere. The old impeller is heavily worn down and needs
replacement. However, I can't find the right part. I've tried the
Globe 815 (exactly the same dimensions as the Oberdorfer B6593), but
it pumps absolutely no water out. When I put the old impeller, it's
fine (pumps plenty of water), but I'm afraid it won't last long
anymore.
The difference between the two impellers is tiny, but visible. The old
impeller has a diameter of 2_1/8 inch, while the new Globe 815 is 2
inch exactly. Also, the height of the old impeller is 29/32 inch,
slightly larger than the Globe's 7/8 inch. Both have 6 blades and a
1/2 inch shaft.
I can't find out which impeller I have, and I definitely can't find a
suitable replacement. Can you help me out with this? An alternative is
to replace the complete water pump with a new 202M-3, but I'm hoping
this won't be necessary.
I'm open to creative solutions, e.g. buying a larger impeller and
cutting the blades to the proper size.
Thanks!
