So, after some trials and drives it seems, that in large part my problems are solved.

Lean to port I could solve by simply redistribute the heavier things from left to right stowage under jockeyseats or by biotrim, the extrem chinewalk is completly gone as soon as weight is in boat. With 3-4 persons chinewalking is completly gone and speed is still 86-88 km/h.

Motor height seems ok, because with a heavy person on jumpseat motortrim has to be reduced else propslipping occurs much sooner.

I also have an OP 6.3 with a df140 on. When I first got it I also noticed lean and a pull to port.

After alot of tinkering with trim I realised that this set up was much more sensitive to trim levels than any of my other boats.
Millimetres can be the difference between heavy steering with a pull to port and a perfectly balanced boat that's easy to flick about.
38 knots 4 up with full tanks (2x70ltr up front) is fine for what we do. Flat calm or rough seems to make no difference to this boat! I've done the fast boat thing and this feels safe and fast enough these days, especially with kids and wife on board.
A 175 would be nice but I agree with some of the other posters, 200 is alot on that hull. On the flat maybe ok but I wouldn't want to rag it wide open on the rough stuff.
Your boat will come in to its own out at sea...just go easy on the throttle!
