X-15 prop

What's the stock prop on an '08 X-15? How does it perform vs aftermarket stuff from either OJ or Acme? I know even just a couple model years earlier it was an easy decision to spend $600 on a good OJ or Acme replacement, but I haven't heard any discussion on this about the '08 boats. Anyone know if the stock props have improved enough that replacement is not necessary?

I'm getting an '08 X-15 soon... primary use is surfing, some wakeboarding. Probably factory ballast, maybe 500lbs over factory... not 100% sure yet.

Thanks in advance for the feedback.

I don't have the boat here, but it definitely has an OJ prop, I want to say 14.25 x 14, four blade. We have surfed successfully with stock ballast, but it was absolutely fantastic with about 8-9 people in the boat. My son is doing really well with the surfing. The rest of us are trying to catch up. I'm goofy and not doing as well on the starboard side. The wake is WAY better on port. Tried riding it "backside" on port, but it seems much harder to learn. I also think I want a more "buoyant" board for the big kids. My son does fine on the skimmer style (Hyperlite Broadcast). We have done deep water slalom starts, wakeboarding, tubing and surfing. Haven't really tested the top end yet, but its at least 40mph. So far, the performance is fine, but I too will order another prop as a spare, and if there is something better to be had, I would like to know about it. Couple of pics for fun

KGROVE - OJ is spec'd in the '08 literature, but no size info. Everything I read hear says "email Eric at OJ". Can we have that email one more time?

I have an OJ 14.5 X 14.75. It has a little more pitch than the 14 but it seems to get out of the whole just fine. I think it's a good compromise for overall performance. I would suggest trying a few and seeing which one you like though.

Pulled my stock OJ and went with an Acme 1479 (14.5X14.25 .150 cup). Boat performs much better on the bottom end without effecting top end and fuel consumption.

does a higher pitch number give less torque and less high end or visa versa?

The lower the pitch the stronger low end. More pitch less low end more top end. On paper anyway.

Not sure if that's stock, but from my experience with that prop on my X-star I think you would like it better. The first prop you listed is for high altitude and/or very heavy ballast.
