My bracket has a 2.5' setback, so that rule of thumb says my AV plate should be 2.5" above keel. However as you can see in attached pic, it's 3.25" above the metal rail extending aft from keel. I have since raised it to 4.25" and AV plate is STILL underwater, so it needs to come up about another inch! Therefore in my own experience that trade factor would seem to be about 5.25"/2.5' or roughly 2" per foot of setback!
thanks bushwacker that makes it mutch clearer dave2400
