Yeah, I'm with everyone else. Those numbers are NOT right.... I've just run my prop calculator and something is off.
If the boat is getting 35mph with a 22" prop, the max revs are at around 4000, which is way too low (that engine should be doing 4400 to 4800 at wide open throttle)....
If it is making the right revs with a 22" prop, (which in a 22' boat I would SERIOUSLY question!) then the speed will be more in the order of 42mph...
To make the right revs at 35mph it would have to be running a 17" or 19" prop....
But the big kicker is 140hp in a 22' boat... 35 yes, but not mph, more likely kph.... But running a 22" prop, NO WAY! Think more in the order of 15 or 17"....
