I've found they are sensitive to prop type/condition more than a rigid floor. If your prop is an OE type and not obviously badly out of shape it should be fine though. 1/4 turn of slack in the transmission sounds about right.
As discussed you can't make any judgement unless the floor pressure is spot on.
I think you have all solved it, thank you.
The more i think about it the problem has been when someone is sat on the floor which will distort it.
It lives on davits, it gets hot and is upto pressure in the sun.
as soon as I drop it in the water the cold water will be dropping the pressure.
I will pump it up after Ive launched it and hopefully it will be fine and no need for a new prop/gearbox.
