[left]If they are both the same year there should be no difference between the 20 hp and the 25 hp mercury. If you are questioning the years call a mercury dealer with the serial numbers and they can tell you what year they are. call Marine Products at 801-973-4017. Most 25 hp merc's came stock with a 12p so the 11p should work well.
