You are burning 1.5 GPH at 27 knots :jaw or is that 1.5 miles per gallon? I think I burn burn 1.2 GPH at idle.
dwtanner said:I have a 1981 Grady White Wahoo 256 with a 454 straight inboard. It has a 1.72:1 Borg Warner gear and 16" prop. I get around 1.5 gallons per hour at around 3800 rpm. Speed in that range with boat averagely loaded in freshwater is around 27 knots.
Like I said though, this is a straight inboard, not an inboard outboard.
