Currently at 8.5 hours and I am noticeing a squeaking sound coming from the engine. It almost sounds like it could be a pulley (it reminds me of a girbal wheel sound) but I cant tell for sure where the squeaking is coming from. The speed of the sqeaking is realted to RPM and is more evident at lower RPMs and not noticable at higher RPMs. Oil press and temp has been good. However I did have an Engine Light come on twice (no alarms or Codes on the BIG) when moving at low RPMs. I believe the engine light had to do with engine temp as I noticed that the temp was over 160 each time the light whent on. After restarting the engine, all was fine.

I only have a few hours to go before i take it in for a 10 hour service, i'm wondering if the sqeaking is a concern that I should take to boat in sooner or wait (assuming its just something minor like a squeaky pully).

was your engine light in the center gauge ans state "ML" ...What ever that means?

Our did the same thing over the weekend... started at 7 hours.

Yes, Its the little orange engine light that says ML or NIL or what ever inside the engine outline. Its located in the large center gauge. I think the first time mine went off was around the 6 or 7 hour mark.

I am wondering if than comes on when the engine temp reaches 160 or 165F. I think the BIG temp alarm is set higher :confused:

Are you getting any squeaking from your engnie?

no... Just issues with zero off, BIG, and the tabs...oh any the outside temp reads 32 degrees and the shallow ware alarm goes off constantly.

Interestingly, my 6.2 started having these exact same issues you guys are having. My boat is going in for it's 10 hour service and this hopefully will be resolved. Really could hear the squeak at low rpms, almost like a belt was slipping or something. It was still there at higher rpms but the engine noise tended to drown it out. Hmmm, the fact that we're all having the same issues is a bit concerning. I would like that BIG software upgrade as well. Hope my dealer has that available to install. Fortunately, my PP is running well and I don't have any trim tab issues. Just want everything to be dialed in and minimize these little things popping up.

You should be able to adjust the shallow water alarm on the big. I think a lot of people are having issues with the BIG and integrated systems into the BIG.

I was told when I picked up the boat that the outside air temp is a glitch. Not sure when a fix will be out.

I just got my response on the outside temp issue. The BIG arrangement does not have the capability for outside air. They did not even include the capability in the wiring harness. medallion was to remove the programing but did not. I was told...If a fix ever occurs, it will be to just remove the item form the menu.

As far as the shallow alarm, I took it all the way to zero feet, but still a issue.

I had the same answer from the dealer but it is very strange that in the user manual they do describe how to use the air temp on the touchscreen, there is even a picture of the touchscreen where you can see the air temparature.......

yea, I think the response was a bit muddy myself...I struggle understanding why they market something, don't follow through and it is our problem. Heck, I'm still waiting on the bimini with no delivery date in sight.

To me its clear that the manual was created having little real knowledge how the systems are supposed to work. IMO there is very little how to information/descriptions, instead high level descriptions of what they are. Also when you see a disclaimer like the one below, I just proves an unfinished product;
"Please note that some refinement of these gauges was in progress at press time. therefore, the video display gauge in your boat may have some mionor variances to what is described in the manaul. MasterCraft strongly encourages you to review ALL instrumentation with your authorized MC dealer prior to operating the boat for the first time, and at any time during ownership of the boat if you are uncertain as to propoer and applicable functionality." IMO this is crap!

Also, what the h*ll does this staement mean... Its on page 84 of the manual

"NOTE: The trim tabs and ballast tanks are Plug'n Play tabs. Any other tabs or tanks are not displayed. :confused:

Seems to be to much cost in our "cheap boats" to include a temp sensor that costs just cent's...or just to choose a gps sensor with a temp sensor included... maybe Medallion/Mastercraft lost their programmer, or he is unable to just program the temp readout into the firmware... i don't get it...

I'm sorry Mastercraft but you seem to need to get things working on our side! All these things are not rocket/nuclear science, just get some good engineers and programmers (maybe german ;) ) and get on it, otherwise I'll have to have lawyers breaking hell loose under my dealer by the end of summer. :mad::mad::mad:

I heard the same squealing noise over the Memorial weekend, the first real time we had spent in the 6.0 X-35. I did not trace it down but it sounds alot like a belt slipping. When did you take delivery of your boat? I took delivery in the latter part of april and the dealer had already installed the upgrade or patch, if you will.

Mine did the same thing. Then I looked at big screen and at the bottom it read " Reminder Oil Change Needed"

Mine did this yesterday as well at about 5 hours. No engine fault on BIG showing. It cleared when I restarted the engine. The Ilmor manual says it has something to do with emissions controls.

2012 X45 6.0 ILMOR. I have not experienced the squeaking, but I did get the MIL engine light once when we were moving at low RPM's for a while pulling my 6 yo on a kneeboard. It then reset and turned off when we restarted the boat. The manual implied that it is related to an emissions sensor. The first time I took it out we actually threw a bunch of engine codes due to some faulty sensors, so the motor went into safety mode. We had to limp back to the dock and have the dealer fix it. For a minute I was afraid that was happening all over again. It also showed me an "F" on the gauge. Any idea what that means?

I can't get my rider profiles to load on the BIG and the dealer said they can't do anything until MC gets it figured out. VERY FRUSTRATING ON A NEW 100K + BOAT!! Not to mention very embarrassing when my Tige and Malibu owning friends are laughing at me for spending that kind of money on a new boat.

I sure hope that this is not true!! My 07 had outside temperature. My cars all have it. I love this boat, but right now am wishing I would have bought a used '07 X45.

I am not generally a negative person, and I love the layout, wake, handling of the X45. I love the power of the ILMOR 6.0. I am just disappointed at the lack of attention that has been put into small little details, and the fact that I can do nothing about it. I am sure that in the end the software bugs will be fixed, and that we will enjoy this boat for years to come, but it is hard to be patient after spending the $$ that these boats cost.

100% agree. Ive spent 80-90k on plenty of vehicles and never had these type of problems. What gives MC? Get this stuff straight.

The "F" stands for forward I believe. I know because the "F" changes to "R" when in reverse.

Thank you for the insight on the "F". I will watch that more closely next time. I thought it came on randomly when driving one time...we'll see. I will say that the X45 is an amazing boat for our family and friends. We'll get it all worked out...

I had the belt squealing issue on my 2012 6.0L 197 back in Sept./Oct. Ilmor had a fix for it, seems that some of the pulleys were not balanced..causing this. Ilmor replaced the tensioner and pulley...never a squeak after that.

6.5 hours now with 2012 MV8 6.0 no engine squeaks to report.

Mine has now 20 houres on it (2012 MV8 6.0) and i have exact the same squeaking in lower rpms since the beginning i own my baby. Its only between 1.000 and 1.300 rpms. Has anyone of you fixed it? Or should i ignore this?

Do not ignore it. I thought that mine was only squeaking at low rpm but found that the engine noise was covering up the squeak at higher rpm. You could possibly have the pulley problem that I mentioned previously. First of all, check the tightness of alternator bolts as the unbalanced wheel will loosen these up.

Thanks for the reply! I will check it.

I have the 6.0L too and mine squeaks. Is this just the 6's or does anyone else have the same squeaking? Is this the belt or a pulley that needs to be replaced or just an adjustment?

Ive tested it. In no load running there is no squeaking. But if i put the gear in, there are this squeaking. It sounds like coming from the transmission.

I have a 2012 X-25 with the 6.0L Ilmor ...

I am not getting the squeaking, either ... and my rider profiles have been ok ... but I did get the MIL light today and I also got the F that illuminated on the VDIG.

One thing I noticed as this all started was that we had 1/4 tank of gas ... and then the tank showed empty (almost immediately). I shut down and cycled power, but the MIL and the LOW FUEL warnings were still there. I raced over to the lakeside station to fill up and the boat only took 159 litres (I believe capacity is around 225 litres). After a quick call to my dealer, we deduced that I had a stuck float in my gas tank - so I took her for a hard run and, sure enough, the LOW FUEL warning disappeared and I showed a full tank of gas.

After a good surf sesh, I noticed the SHALLOW WARNING came on, reading 3.2 ft of water when we were in at least 120 ft of water. Then the MIL light came on again ... and this is where the F appeared for the first time.

What the F does this mean? 8p Seriously, what is the illuminated F on the VDIG?

The "F" stands for forward I believe. I know because the "F" changes to "R" when in reverse.

Ok, that makes sense ... but does it always light up? This is the first time I've seen it (just over 19 hours on the boat) ... and I use FORWARD all the time! ;)

I get random shallow water warnings as well. My fuel gauge is all over the place. Was reading almost empty and she only took 120L.

Ive uploaded a Sound file where you can here the squeaking. Beginning at 0.13 and ending at 0.19 sec. Recorded infront of the transmission. Hearable between 1.000 and 1.300 rpm. If not in gear, there is no squeaking to hear. Is this the same squeaking you all mean?

Thats different from what Im getting. Mine sounds like a hamspter wheel at low RPM. A constant chirping sounds. My dealer replaced the belt but that didnt solve it:(.

The "F" that lights up in the VDIG, It should come on as soon as you put it into FW gear and remain on unill you put it into neutral. Personally I wish they would have made the "F" green as the orange is more suited for Caution lights (aka engine light)

I was having the same problem and it was also throwing my belt on my 2012 x-45. I finally got it fixed Saturday and I was informed that there is now a "service bulletin on the FEAD bracket" this bracket evidently aligns all the pulleys and is recalled as it is causing pulleys to go bad i.e. chirping. You can read about my ordeal http://www.mastercraft.com/teamtalk/showthread.php?t=54763&referrerid=55029

I would get with your service advisor and tell them about the bracket. My guys said that have ordered 12 brackets to repair chirping pulley complaints.
