With a top speed of 43.5, this boat was right in line with where the performance should be. Faster becomes uncomfortable for any crowd, and slower has you wanting more. Cruise speed was a comfortable 16.2 with a 4.8 gph fuel burn, but my hand seemed to settle in at xxxx rpm which produced a 26 mph run. At that speed I was burning only 8.7 gph and could keep doing so for 134 miles.
