Figure about 30-32gph at 3150-3200rpms. Not sure about the cruise speed at that rpm with a gas 35.

At 18 knots I am turning 2750-2850 and burning low 20's in gallons per hour. If you crank her up to 3200 you will see 27-29 GPH. That 400 rpm makes a big difference in the burn on my boat.I have twin rebuilt original 454 mere's upgraded to Crusader specs/parts. The castings are Merc.
