The real sticking point comes it hull effeciency. If you only compare fuel flow at X rpm the results are skewed. For instance my boat wallows by comparison at 3000 but at 3200 it feels loose and wants to run. This of course depends on tab setting. One power package may look very economical at 3000 and another not so good. But how many RPM do I need to turn to get to the speed the hull free's up if I am running a lesser motor with smaller pitch prop?
