John,
I purchased a new "high output" water pump from you this summer, but it did not have "HO" stamped into the water pump. I have a 1997 take-out engine, and it does have "HO" stamped on the OEM pump. Should I be concerned that the new pump is not actually marked with "HO"?
I compared the impellors from the old 1995 pump to the new replacement model, and the new model was definitely larger.
Thanks!
