I would guess that it makes no difference to the flushing quality, and
I reckon it's unnecessary and dangerous to have the motor in gear with
the prop turning while flushing.
It also has to do with getting water to the engine. With the prop in
gear, in a confined space, there is decreased water flow to the
engine.

There is no need to turn the prop anyway.


I just looked up the manual for my 1994 Johnson 25 2 stroke.
The recommend:
placing engine in vertical position in area with good ventilation and
drainage
cover two small holes on either side of gear case with tape to make sure
enough water travels to the powerhead... remembering to uncover after
flushing
install flushing device & garden hose
place shift lever in neutral and remove prop
start water... keeping pressure between 20 and 40 psi
start engine... run at idle only and at least for 5 minutes
check water pump...steady flow must be coming from hole
then leave motor in vertical position (after shut off) to completely drain
the powerhead.

That's word for word from the operators manual.




THat's a lotta work to flush an engine.
