Default Fuel Flow meter for yamaha 70TLR

My skiff is a 2007 Beavertail B2 powered by a yamaha 70 TLR. Ran a 67 mile trip this saturday and burned 12.6 gallons which means i was right around 5.3 miles per gallon.

I am looking into figuring out in what throttle range does my boat perform most economically and none of my gauges show gallons per hour or miles per gallon. I am wondering if there is some sort of fuel flow meter that I can place in line on my fuel hose to show quick and at a glance my gallons per hour, from which I could easily calculate miles per gallon using my speed over ground.

Attached is an example of a fuel gauge from northern tool that measures total fuel used, which could be interesting to know, however I am more interested in flow.

Let me know if there is something similar or simpler that I can do to understand fuel economy on the go with this motor on my skiff.

Thanks,

Yeah I looked into adding one of the factory Yamaha gauges, but 1. I just finished rewiring the boat and don't have room to make more holes in the dash, and 2. was just looking for something as simple as adding an in line meter to the fuel line.
