"My 42 Post is 40,000 pounds +/- not including the Tuna tower. I have TIs 485hp. Bottom line @ 2000 rpm I'm burning 40 gph @ 21 knots. Ughhhh"
 
My engine is 350hp and my fuel

My engine is 350hp and my fuel consumption is:
350hp x 0.746kw = 261.1kw
0.15kg x 261.1kw = 39.165kg
39.165kg / 0.82 fuel specific gravity = 47.762 ltr/hr or 48ltrs/hr
