Make sure you check the alternator bracket. Those 2004 MCX's had a problem with the bolts that secure those brackets breaking (happened to me and several others here) and if those bolts do break, your belt will start squeaking as the first sign of that. MasterCraft should replace those under warranty with an upgraded bracket and a different set of bolts. It's a known problem.

300 hours I think you are due to just replace that belt.

I believe my belt started squeaking right before the alternator bolts snapped off. (2003 MCX though)

already did the bolt thing - think I will check tension, if that does not fix replace belt.

Dusty, I have a 2004 xstar with the 350 mcx, my belt has been squeeking for a year and I asked them to look at when they winterized it, they found nothing worng but if I run is slow, about 1200 rpm it still squeeks, let me know what you find, I have not checked the alternator bolts but will do that now.. I have 270 hours as well.

bolts broke again. waiting to hear from dealer and factory. Has anyone had a bracket that was retroed or improved?

I thought so. What tends to happen is that the bolts break, the owner takes the boat in and the dealer just replaces the bolts...either out of ignorance of the design change after 2004, or because they want to get the boat back out the door quicker without ordering new parts.

Anyway, look at this post for info on alternator brackets (http://tmcowners.com/teamtalk/showpost.php?p=121578&postcount=31).

Thanks for the link, My bracket is the newer one, don't have stainless bolts. Really concerned over the 2nd go around. I now have some cast iron around taps chipped out due to breakage. I am curious to see how MC will help to resolve as it was just fixed in warranty, but now it is out of warranty.

how long ago was the work, the shop should warranty their work for a set period of time ... irregardless of the mfg. warranty

What does the alternator bracket look like for an '06 or '07?
Any chance they switched to an auto tensioner yet? If not, why not?

Try some bar soap on it. As a former farm boy we used barsoap on belts in combines, mowers, ect. and had better luck with it than belt dressing.

never had good luck with belt dressing, seems to leave a film after you change the belt down the road and just causes more problems.
