The mother of all HP Questions

[Genie Aye]

First, I also run a 200HO Evinrude Etec like bgreene.
Speed capability in excess of 50knts.
Economy I do as well or better than any 4 stroke on the market. I average 2.4mpg to 3.0 mph depending on load and water conditions.
As for water play, skiing etc, 2 strokes just come out of the hole faster..period.
As for trolling, I have around 750 hrs trolling on her, around 2.4 knts at idle.
