I have an '05 2170 with a 2stroke 150 yamaha that i bought used. It has a four blade prop, (not sure of pitch) it will top out at 47 mph loaded fuel, three people(about 650lbs) and gear. It's only 4800 on the tach wide open, so it's not working to hard. I thought about changing props for speed, but the hole shot and mid range power is really good and i don't want to mess with that. I cruise all day 4200rpm @ 40mph. Overall i'm happy with the rig. Everyone likes more power but it's all in what your pocket book can stand.
