Guesstimate My Range

[fishingwithblue]

I replaced with a 40 gal as well and last weekend went 33.7 miles to J bouy, 33.7 back to dock and maybe 5 misc miles back to fuel dock. Thats a total of 72 and a half miles. It took 28 gallons to fill it back up and my DI Evenrude needs new plugs and injectors cleaned out. That would leave approx. 30 more miles to empty for a possible grand total of 102 miles on a 40 gallon tank @ 2.5 mpg

Hey Airslot, usable gallons is what? Because the first time I filled up the 40 gal from bone dry it only took 36 gal. Are tanks rated slightly lower than what they are ?
