      Would this prop work well on X24? Other suggestions? I have little kids who love to tube and I run over 4K rpm pulling them constantly.

        I couldn't find any info anywhere and didn't want to start a new thread for something simple. I have had a new '19 Xstar for a few weeks and just getting acclimated to the boat. Love the thought of trading out the stock prop for a different to gain some fuel efficiency and better performance. The boat is currently all stock with the 6000 motor. Just wanting to know what is the ideal set up that some of the 2018-2020 Xstar owners have experienced to really dial in the boat for surf, wake and cruising to get the best wave, smoothest ride, and most fuel efficiency for all three categories. I know people onboard matter and we primarily run with 4-6 people with light gear. Right now using all factory settings for all three modes; drive, wake, surf. On the drive, I've been messing with the speeds and center tab to get to a more leisurely ride less than the factory set 28 mph. Thanks in advance for the advice. 1st new boat for us. Loving the boat thus need to post pics.

          Congrats on the new boat! I run my Xstar with 200lbs of lead in the port locker and the same amount in the bow but centered in the bow. Port lead is needed to make the port side surf wave identical or close to with the phenomenal starboard side surf wave. This does not really affect the wakeboard wake which is perfect just by using the factory settings. I also use the factory Wakesirfing settings but usually increase speed. It is all matter of personal taste. Also the switchback/mid tank can be filled to full rather than the factory setting of 75%. Try it out and go up in speed. Cannot give you a review of the acme 3289 prop as it is not yet on my boat but next week should be able to verify what others have said about the increased top end, decrease of rpm and improved fuel economy.

            Thanks for the info and the congrats. Appreciate the additional info from those that have already blazed the trail. Any insight on the ideal speed with center tab setting for cruising. I have been riding at 25.5 with 25% center tab. Running about 4000 to 4100 rpm. Thanks again.

              I found very similar results as 440 and mike with my x22 6.2 and acme 3289. The decreased fuel consumption while surfing is impressive. With full ballast 5 adults in the boat and 800 lbs of lead the surf rpm are around 3150-3250. Stock full ballast and no lead the surf rpm are under 3000. With 15 adults, 800 lbs of lead, and full ballast there was no chance of planing off for wakeboarding. It just couldn’t do it. But the surf wave was absolutely insane like up to my sisters head and she is 5’3”

              The biggest difference is cruising at 4000 rpm. I saw about a 5-6 mph increase.
              Now that you have had more time with the 3289 on your X22, have your thoughts changed? I have an X22 with the 6.2 as well and am debating swapping over to the 3289. Just wondering if you are still happy with it.

                Has anyone tried the new OJ 18x15.5 prop on an xstar with the 6.2? It’s supposed to improve hole shot, lower rpms, and increase top end. Wondering if anyone has any feedback.

                  Looking at a couple options:
                  1. Acme #3289 18x17.5
                  2. OJ #799-MF 18x17

                  The stock prop is 18x16, a 18x15.5 is less pitch, so for sure hole shot would be better than stock, but lower RPM at a given speed and higher top speed I don't see how that is possible. Especially given the cup is .120 on the 3 choices.

                  Manicmike at 2100' elevation reported difficulty getting on place with a 3289, so thinking an OJ #799 at 18x17 might be a very good improvement(Lower RPM/Higher Top Speed) over 18x16, but not as aggressive at 18x17.5?

                    I don't see how it would be possible to do all of those things with a single prop...you have to make sacrifices somewhere, there is no magic prop.

                    Just to clarify my experience- with the stock prop the boat was a monster, pulled very hard even with full ballast + 400 pounds of lead. After switching to the acme prop the boat still had what I would say "normal", or "acceptable" performance...but you could tell it wasn't as good as stock

                      MM and 440 have provided great data. I have found the Acme 3289 to be a great choice. Everything is a compromise and I feel that for the way I use my boat this was a good decision It's much quieter and seems to have lower fuel consumption. If you're wakeboarding with a big crew and full ballast the Acme isn't for you.

                        Travis at the boarding school recommend it through Instagram. It’s the new oj wake pro v4 that has a variable pitch and apparently some other new technologies in the blades. We ended up getting it in July and I’d say the boat pulls even harder than stock and we didn’t lose any top end. Definitely did not gain any top end though.

                          I spoke with Braden at ACME over the past few weeks... he recommended the ACME 3319. its still an 18x16, but they are claiming 200-250 in surfing RPM and 1 mph gain on the top end. We will see this spring when we put the boat back in the water. Really great info from them and I will share back with our experiences. But for those of you shopping, might be worth a try. Told him we where looking to lower surf RPM and we use our boat from here in Colorado to a lot of it's life at Table Rock. Surf full ballast with 500 lbs of lead and typically a crew of 4-6 adults and 3-6 kiddos. I also agree with Mainiac, it's a ROCKET with the stock prop at lower elevations like Table Rock, less here at 6K feet in Colorado as you would expect.

                            1. OJ 18x15.5 V4 - kind of what you should expect, pulls harder than a OJ 18x16, variable pitch and no top end loss. Doesn't seem that big of a change?
                            2. Acme 3319 18x16 - 250-300 drop on surf RPM, little gain on top end
                            3. Still seems to be OJ 18x17 might be the ticket, drop surf rpm, should be a good gain in top end, less aggressive than the Acme 3289

                              I emailed an online prop retailer and they suggested that if I make this change my fuel consumption may actually go up while surfing. Thoughts? Engine having to "work harder"? blender guide

                                That has been discussed on this forum before- you are not the first person to be told that. Maybe it’s true but I have Not heard any real world experience with that happening. As long as you are not going crazy and moving to a crazy prop and keeping the rpm’s within reason- I don’t see that happening.
