I ran my both an 18sf and 20ma with a Merc 2.4 225, 2.4 200, 2.4 175 and 2.0 150 . . . never got less than 2.8mpg 4000rpm cruise with a calibrated fuel flow meter. Even at WOT (51mph with the 2.4L 225) I never saw less than 2.0MPG (51 / 22gph = 2.3gph) on any of the rigs.
Propped WOT 5800 a 2.0L 150 doesn't burn more than 16gph . . . It doesn't feed more fuel than that through the stock carbs unless you modify them.
Eggs 2.5L can . . . but that's a different story.
