So when a boat is burning 5gph and at WOT (propped correctly) and burns 10gph at WOT it is at 50% load. It's "running your boat at 50% load or running your engine 1700rpm at 50% load.
Where this fails is lets say you are trying to run with a massive load of barnacles on the prop. Push it up to 1700 and that is all it does. Lets say at 1700 full power is 7.5gph, and at normal rpm full power it is 10gph. That would calc out at 75% load, even though engine can't make any more power.
Still not clear to me how the various mfr's actually figure this.
