Volvo Penta AQ151A, 151B, 151C, What is the difference? (need water pump for 151C)

[Buck Horn Deer Farm]

I am looking for the proper circulating water pump for my AQ151C. It is a 1988. The casting # is 1326343. On ebay, the same pump has # 1378809, 271975. It looks like there are three types of impellers used in them. What do I need to look for to get the proper pump? Are auto pumps the same?

According to the VP store link below 1378809, 3547560, 9141220, and 1275148 have been replaced by 271975 for item 25 water pump

All the part numbers above should work
