From what I have seen, EFI engines are generally pretty close to the HP divided by 12 for the WOT GPH usage.

Yes, that is pretty much what I was thinking, based on other Merc EFI engines. That puts the 850 closer to 70gph.

mid corner, drives turned, engines bound up and accelerating, you might get 65-67 gph, wfo in a straight line the engines really don't burn that much, especially in a cat.

Cat, V or cruiser, does not really matter that much.

For a given engine, if you make constant HP, for a specific period of time, you will burn relatively the same amount of fuel, in any boat. Weather we speak in terms of megajoule (MJ), or British thermal unit (BTU), a gallon of 93 gasoline, has a constant energy content, and can produce a specific amount of HP, in a given engine, regardless of the work the engine is doing. Remember 1 mechanical HP is equal to 550 foot-pounds per second, which is approximately equivalent to 745.7 watts, at does not matter how they are used, they take the same energy to produce.

If you run WOT for a specific period of time, the same engine in the cat, will get farther than the V, and the V will get father than the cruiser, but they will all burn virtually the same amount to fuel.

I understand that, I am just telling you we burn more fuel on acceleration courses than we do top speed courses. It only varies by a few gallons per hour. We account for the 60 GPH and usually have fuel left over actually.

and my notes from Merc say 62 gph for the race 850.
