View Full Version : Prop Recommendation for 2012 X25 w/ Ilmor 6.0

02-22-2012, 01:51 AM
I feel I am turning too many RPM's. I have an OJ 14.75X15.50 @ 20mph I am turning 3100RPM, 25mph is 3800 and 30mph I am turning 4200RPM. When we are not boarding or surfing we go on family boat rides and NO we don't have any extra ballast on the boat. I think the 6.0 has more than enough power to spin a bigger prop. Suggestions please!

13.7 X 17 might be the next step up, it was the stock prop on me '05 X-star.
You can usually find them pretty cheap.

I would shy away from the smaller diameter prop, I don't think it grabs enough water for the high drag of the X25. I had one on my X2 and it was a pig. I think they make a 14.75x17...
Where the spotlight with the cutout of a prop for Eric?

Try OJ 's 5 blade worked great on our '11 x25 with6.0

I spoke with Eric at OJ and he said there are 2 different "cups" that they put on the X25's with 6.0's.....a 110 cup and a 170 cup (14.75X15.50) and he said based on my numbers it sounds like I have the 110 cup. I also spoke with my dealer and they said the numbers sound high as well, so they told be that they would swap my prop out with the proper one recommended by OJ. I'll let you know of my findings with the New prop and what OJ recommends.....

Did you get your prop swapped yet? Curious if you went with the 5 blade OJ or just the cup change?
