Generalizations......
1. WOT outboard burns approx 10 percent HP so with a 200 HP burn about 20 gal per hr.
2. Cruise is approx half that burn so 10 gal p hr etc.

New - current outboard efficiency increased greatly improved from idle, trolling speed up to cruise speed. From the 2 stroke Etec to the newest 4 strokes, fuel burn rates reportedly cut in half from older carb and efis ......

Maybe or even likely electric outboards market position will grow and the energy cost evaluation continues.
