I have a jet boat with the same sieze engine you have with a gallon per hour meter (GPH). And at 3200 RPM you will burn approximatly 12 gallons per hour. You can improve on this a small amount depending on the water conditions. The higher you go in RPM the more gas you will burn.
Hope this helps. Good Luck.

I dont have the same boat but here is what I get.

In fresh water at cruise 8gph at 3000 rpm's (30mph). In the salt and I can't get up and run due to the rough water 12-15gph.

22', hardtop, vortech 496, hami212,7' bottom, 9.9 honda.........about 5800lbs not including people.
