Default Re: New Yamaha 4 stroke numbers

I went out yesterday to do some more break in on the new motor. Here are some more numbers:

Motor: 2005 Yamaha 150 4 stroke 25 " leg (extended transom)
Boat: 1986 SeaCraft 20 ft CC (20'6")
Carrying: One person, 40 gals fuel
Prop: 14x19
2000 rpm 9 mph
2500 rpm 12 mph
3000 rpm 23 mph
4000 rpm 32 mph

I was only able to get the motor to 4700 rpms at full throttle. That doesn't seem like I'm getting what I should. Do I have the right prop?
