Looking at all of my options as I blew out the MC plate on my left side exhaust tip. Seems like it was an issue with 07 boats.

So Im thinking to get me threw summer, just cut the tip so its like the newer versions and install the rubber flaps.

Thoughts, good idea or piss poor?

Thanks!

yeah my whole assembly blew out and have a week at the lake coming up!:confused:

Ordered some regular flaps from skidim and will see if that works. The internal flap would be better as All I would have to do is drill two holes in each tip.

I always worry about mine can you buy new ones or don't they use them anymore? . Also how would you put those flaps in??

Is there a fix for those of us that have an 07 X1 and have not had this happen? does it get loose before it comes off? this is the first I've heard of this...

No not really, boat was louder one afternoon and sure enough the whole piece is gone! By searching the forum this happens to all the 07 boats with these tips.

Looks to me like those internal flaps would just need two holes drilled and those little brass pieces must get crimped together...........but I dont know for sure.

Thats why Im thinking of cutting them off flush and installing the external flaps. Looking at the 08 tips I would think they could be cut down and use the MC logo flappers by taping some new holes in the flange itself.

I really dont care how they look as I dont want water in my engine.

I was told at our local dealer that they donít make the 07-baffels anymore. My whole baffle fell out and we boated like that for 4 months with no issues other than the boat being loud. Out fix was to install Fresh Air Exhaust (FAE). We have been boating with FAE for 4 months now and LOVE it. I would suggest/recommend going with FAE took an afternoon to install and you are ready to go. No change to the wake and boat is quite and music sounds way better now :)

I agree, it would really take a lot of back pressure to get in these cylinders on the MCX. I was just looking everything over and there is actually another wall about 6-7" up the exhaust. This reduces the pipe a good inch or more in diameter, plus that tube immediately takes a 45 deg angle.

The only time I can think of when if at all possible would be during landing........while engine is off.

I like the idea of the FAE what did you buy?

when i lost my baffle i called the dealer and they told me i would be fine till the end of the season. 300 hrs later all good.

i do like fae especially if you enjoy surfing.

I installed the balck FAE which also has the quick release option. By the way there is only one FAE that I'm aware of and I ordered through here - http://www.freshairexhaust.com/

My boat has seen no loss in power, no change in the wake, and no other problems to report. I have a 2007 X1 with the 350 MCX.

The FAE looks like a winner....but why is it so much?

Is it hard to get the old tips out and change over to the 08 style?

Reviving this old thread to see if anyone has done the tip conversion from 2007 to the 2008 tips?

I have contacted three dealers with no return phone calls and would like to fix before spring:confused::o

I haven't done this personally but I did mention my concern to my dealer. He told me that their experience has been fairly good with the tips lasting. When they do fail he said it was a pretty good choir to get them out as the factory used either 3M 5200 or 4200 to put them in place. He also said that they use a torch to heat the tip to soften the sealant then use a piece of wire to cut the sealant around the tip flange along with putty knives and some tapping with a hammer until it breaks free.

Rex Marine sells a variety of replacement tips and silencers to choose from for replacement. I keep thinking that I might on day have to look at doing this also. For now I'm hoping mine will hold up yet another summer.

I show the 07' and 08' exhaust tips as being the same part so swapping to the 08' is not really going to work. In 09' a muffler was added in conjunction with the black rubber flappers. I don't see any reason you couldn't do that. FWIW the 07'-08' exhaust (pictured below) is still available so most dealers are not likely to have converted to a different style.

Even better. How do the replacemts hold up in comparison to the orginals. I'd hate to go through the effort of changing them out only to fail again.

As far a durability I don't have firm numbers on this but in terms of sales/replacements they seem good. We are one of the larger dealers in terms of sales (10th in the world) and service. in 2012 we sold 1, in 2011 we sold 2, in 2010 we sold 1, in 2009 we sold 3 and in 2008 we sold 7 so it appears that the current run is pretty durable.

My 08 doesn't have the exhaust tips. It has the black rubber flapper. In 08 they came out with the fold down swim platform. That's why they got rid of the tips. It doesn't have a muffler either and is loud as hell.

The folding platform brackets were an option on the X-1 so perhaps they outfitted different exhaust tip/flapper on the boats with folders I'm not sure about that, all of the 08' X-1 we ordered had the lift off platforms. It's also possible MC did a midseason change. As of today MC lists the same parts for both.

So they must have changed the welds on the replacements?

Corey do you have these in stock? Can you pm me if so?

Not sure what I hate more the 3m sealant or those damn straps for the exhaust.

Much better now, might not sound as good though.
