That's even better. This way your would only have to raise the engine 1 hole and then drill your lower hole (Yellow color) in the top of the slot or the upper lower hole for some engines.
I now my prior engine could have been raised 1 hole without any problems with cavitation. I was not sure it could go up 2 holes without having to start playing with the prop.
If a person does go up 2 holes and then drills the lower holes (Green color), the engine could not go down any lower with those existing holes.

My drawing is for the possibility of hole position in the transom only. It does not show the holes or slots for the engine bracket(s).
