RE: 22 Bay Scout with 150 Yamaha Four stroke Take off 2 mph for Ttop
Take off 1 mph for full tank
Take 1/3 mph per additional passenger.
That should be about right.
IMHO: you'll be seeing about 44 mph full wot. Cruise with yamaha will be 29 @ 4200 rpm give or take.
I run a 21' with f150. wot bimini down is 49 mph, bimini up is 47. full tank is 45 into wind and 47 downwind. wind and current make a difference. Cruise @ 4200 is tween 27 and 31 pending on wind direction/speed. Average fuel consumption is 3.3 mpg. I also run in a 26' SV w twin verado 175 and it's wot with ttop and loaded is 47mph with 1/2 tank, 46 full tank w 4 aboard. No clue as to consumption but it should be about 2.3 mpg |
