i have an 07 with triple 250's. i get .8 +/- all the time at cruising speed. boat weighs in around 21000lbs on the travel lift and was not full of fuel. what is interesting I find is that when i run the boat with little fuel, my consumption is the same as when it loaded. i figured the twin 350's would be better fuel. maybe those new 300hp with a 19pitch prop would help. i know that in 09 i used just a little over 1600 gallons at 2.90/gallon or 4500+ in cost,. 90hrs on the engines. I have not totaled this year up yet. i try to measure my fuel usage in annual cost, and just compare it to going on a cruise, or fancy trip. now those guys reading this with the single engines, are having a cow on the cost to run this boat. But, we all have our entertainment $.
