Does any one know what the GPH would be on a 40' Sea Ray 13' beam weighing about 20,000 lbs

On my Sea Ray 370DB during the sea trials before the purchase I got 22 GPH on each engine. That's 44 GPH total at WOT.

A bunch. Boat with your wallet close by. I had the carburated 454 mercruisers on my 35 sedan bridge. 35 gals/hr. Replaced them with Mercruiser 8.1 Horizons. Fuel consumption now 23 gph @ 26kts. 40' too heavy a boat for gas. Will expend huge amounts of fuel to get on plane.
