A friend of mine told me that you can pretty much do the same thing with your tachometer. I'm sure going to try this year. Although, my 150hp dosen't really use that much fuel. But, then again, any help will be gladdly accepted.
Actually you really only need to use a flow scan once. Once you determine the GPH and MPG over the RPM range, it is pretty much fixed for the life of the boat. Yes it will change slightly with load but not much.
That said, I like them and my next boat will have one.
