When selecting the prop the cruise speed and desired engine cruse RPM are considered.

If the boat is expected to cruise at 6 -9 K the prop will be selected to accelerate water at that speed.

0 speed will overload most diesel cruisers , and even the sport fish killers with huge engines will belch a black smoke (overload) on a heavy throttle start.
