i had an impros modded 8/16 for my 650sx
what a nice prop for that ski
ripped more bottom end wise, and some mean mid range power too
i also had various compression on that ski as i did head changes, and the prop still worked great
200psi was a nice sweet spot for that setup
did that when 100 octance was 2.90 a gal that was in 2002/2003
