It's going to be totally dependant on the boat, prop selection and drive ratios, etc. I could not begin to guess here without a lot of input.

Most performance boats with twins will be between 1 mpg to 1.5 mpg. If fuel consumption is of any consideration.......buying a boat is not for you.

MPG will vary depending on the boat and efficiency of the hull.
Merc has charts that will show the GPH(gallons per hour) at various rpms though. At WOT, a 496 HO is probably about 35gph.

Exactly! I run my diacom software and record live data. I've determined that 3500 RPMs is my best bang for the buck. I'm burning around 14 GPH and running 55 MPH. That's nearly 4 MPG, not bad for a boat. Over many hours I average around 11 GPH. That's some idle, cruise, and WOT.

A friend of ours has a 41 Velocity we ran 178 nautical miles at a RPM 3200-3600 his average was about 1.6 mpg.

AT WOT 5,100 I get 1mpg @ 70 mph so at WOT my 496HO burns 51.4 gph. MY best bang for the buck is ~ 3,500 also, I get about 3mpg.
