Default Engine Setback

What is the general rule of thumb for setback of an outboard vs transom height? For example..... if the motor is lifted 1 inch it needs to set back X number of inches.

To help better understand, i have a boat with 20" transom and i will be installing 25" shaft motors. As i lift the motors to achieve the 5" difference, how much setback off the transom will i need for the boat to run properly and have the motors get enough water?

I've always followed the 1" up for 12" back rule. Every boat is a little different but it gets you close. So if you are using a jack plate with 6" setback plan on going up 5.5" to start. If she's light in the bow and you still have great bite in turns then go up some more. If the the opposite is true drop it a little.

If I understand correctly, you wouldnt need any set back for what your trying to achieve. Set back would be to get the motor in cleaner water and that would require you to raise it up but simply raising the motor alone would not need any set back.
