GPH question

[RockyRR]

I have a Yamaha F150 4 stroke. Have any of you seen any GPH performance charts on the web? I know fuel usage will depend on RPM's, etc, but a rough estimate of GPH fuel usage would be handy to have.

Thanks,
Rocky

rule of thumb has been 10% of HP. but not sure with the 4 strokes
150hp = 15gph at WOT

Here is a link that might help you find out more.
