05 150 motor break in/gas mileage

[Tacklebuster]

I have a 05 150 four stroke with about 20 hours on it. I am not getting very good mileage at all. I had a 04 F150 and was getting pretty good mileage out of that with about 60 hours on it. With my 04, I could run offshore Halibut and Salmon fishing, put about 70 miles on her and burn 24 gallons of fuel.<br /><br />With this 05 150, I put about 24 miles on her an I burn 17 gallons of fuel. Granted I have far less hours on it and just got the motor broke in but the mileage between the two seems very differant. The 24 miles I just put on her, the engine averaged 5000 plus rpm's and out in the ocean you only average say 4000 rpm's but it still seems like it drinks a ton more gas. <br /><br />I have not noticed a strong fuel smell on anything of that nature. Anyone got any suggestions or input?

I have an '05 F150 with around 25 hours on it.<br /><br />Being the first Outboard I have ever owned (had 3 I/O's before this), I have no other Outboard to compare to.<br /><br />With only 25 hours on this engine and a 65 gallon tank, I do not yet have a 100% valid statistical sample to be sure of gas mileage.<br /><br />With that said, this engine is burning around 3 gallons/hour at what I consider a comfortable cruising speed for my area/seaconditions. My cruising speed is just shigh of 30 MPH and the engine is turning 4200 RPM.<br /><br />Those are the figures in my log book which was put away in December along with the boat for the season.
