The chart is for at a glance as to your current mileage based on knowing your fuel consumption and speed.
Go back to my post #5, click on the link and see the pictures of my dash.
The device in the bottom center of pictures 5-7 is a Lowrance fuel flow device, the top right is a depth finder/gps. By knowing your speed and fuel consumption, math can do the rest.

OK...missed the part about the flow meter...that's what i was looking for!
Thanks, this is good info.

So the flowscan shows ~3900 rpm is the most efficient cruise speed.
When u get over 4k efficiency drops off.
Speed/rpm/efficiency is not linear!
Makes the math a little tricky.

I have never had any flow meter info until i got this new motor. It's included in the smart guage. It really lets u fine tune speed vs fuel consumption. Pretty accurate too. When i fill up i am usually within 2-3 gallons on a 45 gallon fill up. I wish i had trim tabs to even tweak it a little more.
