Start low and raise until you lose lift or water pressure, then back down a click and you'll know exactly where it needs to be. Mark it and you'll have your spot.
You will adjust when needed, rough water takes a lower setting, idling through flats takes a higher, but once you mark your "normal" spot you can put it right back every time.
No two boats are identical, each one needs its special place.
