I am buying a gulf 29 Pilothouse which presently only has a new merc 15 hp prokicker. Does anybody know what fuel consumption i can expect pushing it as light as possible, weather permitted, at or near its hull speed.

Thanks Marty

Hey Marty, the 15hp merc will burn about 1.35 gallons per hour at WOT ( wide open throttle).
I would suspect your best fuel economy would be at about 70 to 75% of WOT and you would be right around 1.00 gallon/hr. how much speed you get in relation to Hull speed is going to be dependent on wind direction, wind speed, and how clean the hull is… but I’m guessing about 5.5 to 6 knots on average.
If memory serves the hull speed on a Gulf 29 is about 7 knts?
thanks Mark
