Your hull and the voyager are the same. The voyager weighs a bit more, but you are running a 250, so the burn numbers might be close. The 225 and 250 ox66 have the same displacement.
Grady claims the voyager with a 225 should get 3 mpg at around 30 mph burning around 11 gph. Our actual is 2.6-2.7 mpg. My guess the discrepancy has a lot to do with ethanol in the gas we burn and the prop is not factory perfect (reconditioned after damage).
If you call or email GW customer service, they should be able to provide you with test numbers.

My voyager 248 with twin 150 OX66 and bottom paint burns more. My best mpg is about 1.7.

She was named "Dirty Girl" it should read "Thirsty Girl."

Twins is obviously not apples and apples through. I just don't want you to get into this thinking that it'll get great distance per gallon.
