Re: 200 hp outboard on 23 Sceptre???
Fred, I ran an '88 Johnson 225 on my '74 Tsunami. I burned about 11-12 gph on the Navman at 24 mph cruise (about 2.0 to 2.2 mpg), WOT was about 37 mph with the motor burning 38.4 gph on the Navman (less than 1 mpg). Pushing cruise speed to 30 mph upped fuel flow to 18 gph, or about 1.7 mpg.
