A good rule of thumb for estimating fuel burn is 1 gallon per hour for
every 10 horsepower. Actual horsepower at cruising speed should be
about 50 to 60% of maximum. Using those numbers you get a fuel
consumption of 9 to 10 gph which sounds about right to me.

Nasty. The 180 hp Cessna I fly burns 7.5 gallons per hour and cruises at
130 knots.
