My 90hp was fitted by Humber. Offset about 2 inches. Made it go straight with the trim tab thingy on the engine. I have never had any leaning problems with the boat. Strong beam winds make it heel, as all boats do.
Steering can lock up at anything more than a fast tickover if the engine is trimmed in/down too much. (Easy to do as the transom is raked and my trim guage no longer works - I have to turn round and look
) Trim up/out and the problem disappears.
Not sure about the wisdom of using hydraulics to overcome the results of bad trim, I'd have thought it wouls put enormous strain on the engine tiller (or whatever)
