Re: Define your terms
The engine revs required are surely a function not just of RPM but also of pitch. As the Maxprop self pitches it will 'select' the required pitch to match the speed of the hull through the water. This relates directly to the one negative feature of such props which is that one is prone to getting restricted thrust at zero speed as the propeller would 'prefer' to have zero pitch (in fact there are mechanical limits) - this effect requires you to use more revs to get away from a berth than you would initially assume.
