All you have to do is look up fuel burn rates versus
RPM for the Yamaha 150 four stroke.

Let me take a guess: 15 gph at WOT, 7.5 gph at 70% of WOT.




That's on the money for WOT...15 gph on my boat, at 41 mph, but your
guess is too high for mine at 4500 rpm, which is 75% of WOT, and about a
gallon and a half too high for around 70% of WOT.
