  • Best Prop For the X-star??????

    Just want to get some feedback about the best prop to run for wakeboarding. I have a 2004 x-star that I am still running the stock 13.7 x 17 OJ. I was thinking about getting a acme, I had one on my Supra and I was very happy with it.

    Anyone know what they run on the tournement boats that are weighted to the max???
    Heard the 14.25x14 is the way to go but just wanted some other opinions?

    Go directly to the man that knows, Eric Johnson @ http://www.ojprops.com/contact_us or contact him by pm, EJ OJPROP, http://www.mastercraft.com/teamtalk/member.php?u=1537
    Be prepared to give him any info he may need, like boat model and year, engine size, current prop, function (skiing, surfing, boarding, etc.), ballast use, passengers, etc. He need it to determine the best prop for YOUR application.

      the 14.25 x 14 is an oj. it is a killer prop for an mcx engine on an xstar. that being said, check with eric at oj and make sure that there isn't something out now better than that for an mcx. i have an oj 14.75 x 15.5 on my 08 xstar with L18. eric suggested both of these props for my last two xstars and he clearly know more than anyone else. i would do exactly what he suggests whether you buy the prop through him directly or through your favorite dealer.

          Scotty, I run the OJ 14.25 X 14.5 on my '05 x-star MCX. For wakeboarding it's great, really smooth, holds speed really well, great holeshot even with the extra 1500 lbs. of ballast that we sometimes have.

          If you do alot of high speed runs down the lake, you may not want this prop. The engine is screaming at 38-39 mph. That's the only drawback, but we usually don't cruise around much, just launch and start wakeboarding. You can cruise around 30 mph no problem.

          FYI I'm using about 6 gals/hour of fuel while wakeboarding. Not bad.

            I have an 08 MCX X-star that came with 14.25 x 14. I actually switched to a 14.75 x 13 with extra cupping based on Eric's advice at OJ. I did this to give me slightly better pull when riding with greater ballast. It actually improved my gas mileage slightly, and the top end is pretty much unchanged. Just another suggestion. As already indicated, call Eric at OJ props and tel him what you need.

              Weighted to the max, I would suggest our 14.25 X 14 LC XMP EDGE 4-blade.

                Hey Vision,

                Just got that advice from OJ -- the 14.75 x 13, that is.

                I am currently running the stock prop that came with the '08 XStar with MCX -- 14.25 x 14 -- and with about 3,300 in ballast the boat doesn't exactly jump out of the hole.

                And boat runs at about 3,800 rpm at boarding speeds.

                What did a switch to the 14.75 x 13 do to your rpms?


                Now, I wouldn't mind reducing the rpms, but I guess that is not compatible with more getty-up.

                  Eric, what prop would you recommend for an 08 x-star, Ly6 750 lb. bags added in the rear and about 500 in lead in the nose? My stocker comes out of the hole a little slow, especially with more than 5-6 people on board.

                      What size is the stock prop?

                        The guys at No Style Productions run about 5K of ballast plus people in their X-Star with an LY6. I ordered up an Acme 14.5X13.75

                        You will hit the rev limiter when unweighted with this prop and you'll run pretty high r's at wakeboard speed but you'll get on plane FAST!

                        For most set ups the OJ 14.25x14 is more than enough prop, this is what the Pro Tour runs with the PWT ballast set up for an LY6.

                          We do have a 14.75 X 13 that the tour boat will run from time to time, depending on the set up.

                            14.75 X 15.5 LC Splined XMP EDGE 4-blade

                            I bought the 14.75 X 15.5 LC Splined XMP EDGE 4-blade from Eric at OJ Props 7/2009 for my '04 X10 running the factory ballast plus a wraparound nose bag and two VDrive sacks that I have been filling about halfway. I was having problems with planing, no hole shot and holding speed with the Perfect Pass with the extra weight and the stock prop. GREAT upgrade, works great in Phoenix, I was at Lake Powell last week (3600 elevation I think) and it worked well there too. Still having Perfect Pass issues in choppy water or with rollers bouncing off canyon walls, but not as bad as before and a I think it is a known issue with the placement of the paddlewheel on my model year. Maybe I'll have to go to the GPS upgrade for the Perfect Pass unit in the future? I am getting a little whine at certain RPMs that I didn't notice before - don't know what that is - hope it isn't some kind of alignment issue but VERY happy with the upgrade! Thanks Eric!

                              Since my post on here in May I've switched to the OJ 14.75 X 15.5 prop and love it! (thanks Eric!) Not running as much weight (about 1500 lbs. now) but performance is great and the rpm's came down some. I think my fuel economy is better, will have to check that for sure.

                              What I really like now is I can run distances across the water without the engine screaming as much as before, plus I can barefoot @ 40 mph (boat top speed is 42 now) instead of 37-38.

                              s worthy, you may need to reset your perfect pass values. Call PP and they will help you out.
