not for that boat.... but for comparison sake, my 18' heavy center console with a 115 2 stroke merc ( carb motor) spinning a 13 1/4 X 18 pitch SS prop runs 6.2 GPH @ 3500 RPM @ 22 Knots... 7.6GPH @ 4K RPM and 26 knots... that's the range i run it in most... bring it up to 5200 RPM( full throttle for that motor) ... 32 knots s#^&#^&#^&#^&#^&g 12.5 GPH.... not alot of bang for the buck after 4000 RPM... this is all calculated through GPS with a fuel flow meter... and judging by the amount of fuel I burn when I refuel, it's pretty accurate ( above 2K rpm.. below that the meter does not read consistantly).. it confirms the old saying.. it doesnt take alot of HP to move a boat... it takes alot to move it fast...
