04 x9 direct drive, 350hp, what prop would you recommend for replacement.

1:1 drive? if so probably a 13x11.5 05 maybe a 10.5

That is a really open question. What are you trying to accomplish? What is wrong with the current prop? How does the current prop perform and RPM's at WOT? <BR>Altitude?

I use the 13X11.5 Acme 3-blade on mine. Blitering hole shot and still barefootable. Mine is an 05. <a href="http://www.boarditup.com" target="_blank">www.boarditup.com</a>

My friend damaged his. He says he has plenty of hole shot but no top end. He has a 125x12 on there now. Not sure what rpm he is running.

I ment 12.5x12
