We have a 2010 X-Star with the MCX engine...and a 14.75 x 15.5 PN 522 prop on the boat....any reason to switch to a ACME prop...or should I buy the same prop for a back-up?

Thanks, Greg

i have an 08 xstar with 8.1L and it came with the 13.7 X 17.5 i immediately asked eric at oj props what he suggested and he sold me a 14.75 X 15.5 what a great prop.


on my previous 05 xstar with mcx i changed to (again at eric's suggestion) the 14.25 X 14. what a great prop that was for the mcx in a wakeboard application. call eric at oj props and ask him what he thinks of that prop. please respond back and let me know what he says. props are so important. we can't make many performance changes on our boats that are affordable but the biggest performance enhancement i have made on each of my last two xstars was changing the prop to what eric suggested. gthlsu

Greg, I have an X-star with the MCX and usually run the 14.75 X 15.5 OJ. It gives me the best all-around performance for wakeboarding, barefooting and cruising.

However I do on occasion run my spare which is the 14.25 X 14.5 OJ when I know the boat will be loaded down with extra ballast and people. This prop runs a little higher RPM (about 300 RPMS more) and will provide more holeshot with over 2000# of ballast plus 8 people. I cannot use this prop for barefooting as the engine hits the rev limiter. Not the best prop for just cruising around either.

My opinion is to have a spare prop that's different than your everyday prop. Gives you some options of what to run.

I'd go with njskier's reccomendation. Keep the 15.5 and get a lower pitch to give you more snort when you need it.
If you're happy with the one you have and simply want a spare, 13.7x17 props are for sale all over the place. They were not the right prop for the application, IMO, but will certainly keep you rolling on the lake if you damage your primary prop and you can pick one up for a couple hundo.

Does anyone prefer one over the other?

PM Eric from OJ.
I have talked to Bill @ Acme via email and Eric from OJ. I have to say that OJ has been very helpful, a little more so than Bill. So soon, my prop upgrade will be a OJ CNC #454 per Eric's opinion on my boat for my slalom needs.

Both are great props and Eric at OJ is 2nd to none when it comes to customer service. My suggestion is get some trials of each and give them a try and see which one works best for you. I have found that some of the decision is subjective.

I've gotten good advice from both Eric and Bill. Just wanted to see how the members feel regarding OJ vs. ACME.
