    My last boat, 24 Superboat w/496HO averaged 12 GPH. I was getting 4-5 MPG in that boat. I could cruise at 55 MPH at 3500 RPMs.

    WOT I'm at 180GPH, basically 1 gallon every 20 second...

    The rest of the time I am not sure we fill it to the brim every chance we find good fuel...

    My Yanmar powered Nor Tech at a cruising speed of 66 mph uses 22 GPH in each of three engines for a total of 66 GPH which of coarse is 1 MPG. My previous 50 NT with 3 X 850 HP gas engines used exactly double that and got .5 MPG at a slightly higher cruising speed.

    525SC's in a 2000 Donzi ZX- 1.12 mpg
    454 Mags in an 89 Scarab III- 1.38 mpg
    260's in my old Chris Scorpion- 1.41 mpg

    I constantly track fuel on everything I have using gps distance verse fuel burned over the entire season. The old Scorp with small blocks I use to have could really suck the fuel for what it was but that was mostly due to the fact you had to be deep into the secondaries to run with anyone. I started doing this years ago mostly because I don't really trust fuel gauges, as a rule of thumb I figure 1mpg and that gives me a bit of a safety net.

    roughly 40 GPH @ 3600-3700 rpms = 60-63 mph.

    WOT I never tried to figure out and don't want to know... As soon as boost kicks in you can watch the needle go down.
