Went for my first run today and tried out my new gadget. Averaged 8.5 GPH running 27mph with a 21' Hughes Craft RiverRunner with a 351W H.O. and AT309 jet. uploadfromtaptalk1336351397641.jpg
Total run showed 10.1 gallons, but the fuel gauge was still reading full. Might have to adjust the calibration when I run through this tank and compare the actual fuel used.
