  • Blown motor 08X2 400 hours.

    Last month my engine started knocking after a day on the water, no alarms, no warning signs. The 400 hour 350 MCX engine has been maintained at regular intervals.Orginally it was thought to be under warranty but in the end I paid the bill. The cheap plastic intake screen on the botom of the boat was broke from an unkown object. Weeds were allowed to pass right into the cooling system eventually clogging the transmission cooler and then overheating the motor. THe argument that I have is why wouldn't the temp sender be able to pick up on the high temp? (it was tested and found to be in working condition and no codes showed up on diagnostics of the engine) THe plastic screen has been replaced with the brass intake that is on most of MasterCraft boats. Why they went plastic is beyond me.
    SO lessons learned:
    1. clean and inspect transmission cooler screen periodically
    2. fully inspect under boat each time you pull it out of the water. (I do this everytime ,but the trailer bunks block the view of the intake unless you really get under it.
    3. If you have the plastic intake screen replace it !


    Check out the pics!

    wow, that is hard to believe.

    i have a 07 x2 and i guess i need to start checking in plastic intake on the bottom of my boat.

    sorry to hear about your problems.

      I don't understand why you didn't get a temp alarm...

      Those weeds caused the same problem as losing an impellar, and I know I got an alarm and "limp mode" when my impellar blew.

        The water temp sender wont see the high temp if there isnt a water flow. I have seen this happen before, but that was on an older boat.

          It's called an Intake Water Strainer

            wow that really stinks for you!!!! I have an 06 X30 and I think it has the brass screen but I perioically check the intake screen. What amazes me is your temp gauge did not increase-did they say why? Does your lake have alot of debris?

              Wow. I check my cooler every few times out. I would have definitely thought a high temp alarm or gauge pegged would have been seen or heard. If there is no water flow you can also hear the motor get abnormally louder, granted that the stereo is not blasting.

              Sorry for your luck! A strainer has been on my list, but I have just not found a unit that is compact enough and quality built. After reading here, it seems the OEM strainer MC is putting on it's boats leaves somethings to be desired.

                My mechanic (not dealer)is going to install a water intake strainer. Most of the high performance race boats have whats called a sea strainer with a flow sensor built for saltwater- probably go with that. My boat spends its time on the Colorado River in Parker, AZ so you can always count on plastic bags, beer cups, and other misc. debri. I think Ski King is right with the temp only being able to read liquid correctly rather than air, adding the flow meter would solve any discrepencies. After spending 5 years of my life drviving a nuclear submarine I tend always watch the guages. And yes the stereo was blasting most of the day.

                  I like this setup, and the fact that it has a water valve to shut off the intake supply. Would be a good thing to have if the raw water supply hose had an issue.

                      FWIW, the diagram is from the owners manual of my SN.

                        Yes that me. The windows are being tinted today! Great pic. When was that taken? Tim at Dirty Deeds Marine and Detail sometimes takes it out when Im not there. Good friend and excellent mechanic to have. Im heading out there this weekend.

                          I saw you out a few times! That was taken over Memorial... I think it was Sunday night that we went to Roadrunner.

                          Tim washed up my boat the week before Memorial. He seems like a good guy. His shop is coming along nicely, as well!

                          Why is the boat registered in MN?

                            I have all of my registration in MN - tons cheaper. I work for the government and move around quite a bit. In San Diego now. I actually worked for TIm all last summer as his detail guy. THe boat is stored at his air conditioned shop now, always clean and ready to go for the weekend.

                              A raw water strainer is standard on all 2010 models.
