A propeller is more efficient than a jet boat.

Fuel economy? At 25 mph, the jet burned 8 gph for 3.1 mpg, while the sterndrive consumed 4.7 gph, netting 5.3 mpg. Above 40 mph, the Sea-Doo consumed 16 gph, the Chaparral under 11 gph. At full throttle both consumed 19.5 gph, but the Chaparral ran nearly 8 mph faster, boosting its economy.
