mercs are like that. you can go to napa, they have a marine book that will have a serial number group. usually merc impellers are the same.they can look up the motor by the horse power and how many cyl., For instance, an 80 h.p-4cyl.-115 h.p. 6cyl. have the exact same impeller. The year range on this example is 1960,s-1980,s. I hope this helps.
