I've searched around but can't seem to find the info that I need. I have a 2006 X2 with the MCX. The prop that I have is a 13.7 x 15, Its the original prop but the PO had it repitched, It was a 13.7 x 17. What size do I need to reach at least 42-45 mph, If that is possible?

I believe Eric will have your answer. But I think if you boat is proped to pull wake speed with a ton or weight in it and you change to get more top end you will lose some grunt in the low end.

I would suggest a 13.7 X 17.5. As Tim said this prop will not have the low end but will run faster on the top end and cruise at a lower RPM for a give speed.

Eric will get you setup with the right prop and you will NOT be sorry for dealing with a great guy like Eric and a great company like OJ Props.

2nd what DooSPX said, Eric is great to work with.
FOr reference sake, I have a 14.5x14.25 Acme on my boat (same as yours) right now. I need it for the hp loss at altitude, but wound out about 5100rpms, light load, smooth water I can get 41-42mph out of this prop. No reference against the OEM 17pitch because I couldn't even make rpms with it where I live.

Thrall - what altitude are you at in CO? I'm in Denver at 5,300...I honestly don't know what size prop I have (just bought last fall) but I'd like some comparison in terms of altitude.
