I was reading an ad for a 20' V hull boat. This general information was provided: Volvo Penta 4 cylinder 126hp motor. Brand new 175 out drive. Like new 20hp Honda high thrust motor with own fuel and battery. This boat cruises at 20 knots, 2gal/hr, 11mi to gal, 91octain, over 250 miles cruising range.
Seems impossible to me that a 126 hp anything could only burn only 2 gph at cruise, but I don't know anything about this type of power plant. What do you guys think
