    The REALITY is the 450hp engine works less and is stressed less than the 350hp...Further in resale value look in the NADA, the 450 is still a $10,000 add to the boat where the MCX is not as a matter of fact it is the engine that was considered standard so it adds nothing even though it was an added cost option...game, set and match...enjoy your big block!

    My MCX and I respectfully request you leave reality out of this. Anyone have any recommended treatments for blocktile disfunction? I just learned I have a small block

    I am sure I will adjust and can lead a normal life given time to heal.

      What's your budget

      Truly, I think the stepped hulls with more wetted surface are where you will really notice the hp ... when I look in the waterskimag.com buyers guide the older style x30 (not stepped) get up near 50mph with the MCX, which is adequate top end for me ... I think you should get 1mph for the first 50K, after that the curve becomes somewhat exponential IMO (chrome costs $$)

      here is some info I ripped from waterskimag ... also, here is what BigMac had out of his 230vrs with a prop swap:

          Mike, what's your take on an engine that is 3 years old and has only 28 hours on it??? That's alot of sitting, what should be looked for?

            How on earth can a 23 foot Vdrive top out at 48mph, while my lean and mean 197/X7 top out at 44-45mph?

            Yes, I have the MCX.

              Change the fluids, filters and you should be okay. If you want to sleep better at night have the compression checked and a leak down performed. I wouldnt worry too much, but better safe than sorry.

                Flat bottom boat VS. a true V-Hull...your 197 never gets the "boat" up and out of the water, where the V-hull actually begins to ride on the "pad" in the rear. Short answer? Less wetted running surface at WOT.

                  MYMC,

                  Any idea the top speed on the X1 with the MCX?

                  If you were to recommend that boat to me, would it be with the Powerslot????? I hope not, but want to check.

                    We have an 2006 X-Star with MCX. Most of the time we run with 3000+lbs of ballast. We had to reprop and performance is OK now, but we are constanly running at around 4000 rpm. We have to reprop for cruising or skiing, as we will overrev at about 32mph.
                    If you will use the boat with standard ballast only, the MCX will do, if you plan on doing serious wakeboarding and will add ballast, get the 8.1.
                    We are perfectly happy with every aspect of the X-Star, but we would get the 8.1 if we would get a new one.

                      All our V-drives are 1.52:1 so you need not worry, you already have a PowerSlot. The X1 should run 45 to 47 with the MCX.

                        THanks Mike, I was just curious with your knowledge and all, if you had any feelings one way or another. I DEFINATELY don't have a problem with a low hour boat (mine turned one year old yesterday and I'm at 180).

                        I asked because I have had issues with older cars in the past where they were extremely low mileage, but things kept breaking on it (mainly the rubber parts had dried out).

                          I hit 49 MPH at WOT with the MCX in a 05 X2 last year. No GPS to confirm, tho.......Must get the speedos dialed in with GPS this year.......

                            Thank you...


                            I want to thank everyone for their advise and support. Particullarly, I would like to recognize "Pendo" for the extra effort. Not only did he support this thread with some great data, but he emailed me more. Made my decision last evenig an easy one to purchase my 2003 Mastercraft. That is correct, the 03 X30 with the 450 horse 8.1.

                            I highly recommend Team talk and the folks that make it happen. Any future newbies need only read this thread to understand the real value.
