I am starting to look at an X45 and was wondering if the MCX350 engine is large enough for this boat or is it much difference to get the 8.1 engine in this boat as far as performance

MYMC Should be chimming in at any time for this one. With the size and wetted surface of the "yacht" I would say "can you ever have enough power?"

I have an 06 X45 with the MCX and I find it has plenty of power for what we do. We are a family of four and usually bring another family along with us. Boat tops out at about 42 (new prop may help this, just not installed yet). I'm happy. We wakeboard and surf, cruise at about 30.

Others on the board suggest the 8.1 is the way to go, but it's about a 8 to 10 K upgrade so you have to figure out whether your budget will support this.

Oh, but if you "play" at high altitudes where the air is thin you may wish for the additional performance of the 8.1. We "play" on lakes in the sierra foothills between 800 and 1500 feet in elevation so thin air is not a problem.

The Mcx Is A Small Engine ... The X45 Is A Large Boat ... If You Can Afford It ... Put A Big Engine In A Big Boat ... If You Cannot Afford It, Put A Big Engine In A Small Boat ... If Your Salesman Convinces You To Put A Small Engine In A Big Boat, Have Him Take You Out To Dinner With His Commission

P.s. - I Don't Care Who I Offend, The Mcx Is Too Small Of An Engine For An X45 If You Are Going To Use It As Intended (lots Of People, Ballast, Big Body Of Water) ... But Then, I See A Ton Of V6 Mustangs Rolling Around ...

Will the MCX be able to handle the X-45, yes. Will the LY6 or 8.1L do a MUCH BETTER job YES!

We haven't ordered any X-45's this year w/ the MCX. We have multiple 07's with the LY6 and one left w/ the 8.1L.

There is a reason for that :)


Where are you located in the midwest?

Nuff said...if you end up with the MCX be prepared to spend time and money changing props and then buying gas for a boat turning 4000+ RPM in wakeboard trim with a top speed of 39.

I completely agree with PendO and MYMC on the 8.1L. I have a 2002 X30 with the 8.1L and I love it. Another thing to think about is if you can not afford a new X-45 with the L18, then you may want to thing about a used one. I got my 2002 in 2005 and let someone else take the depreciation over the first 3 years (when the curve is the steepest).

Have fun in your search.

Take a look at this and decide.

I bought used....... and the MCX performs fine. I would say like everyone else if you can budget the 8.1 then no question. I was actually looking at used X-Stars and just happened across my boat. I am in the Little Rock area if you want a comparison drive let me know.

forgive me if I right click and save ... up till now I have only dreamed of having those curves readily available as several of us have discussed how nice it would be to have information available to customers and potential purchasers - to more easily compare engine specs, perhaps they were always readily available and we did not know where to look, or perhaps you just made my Tuesday ... thanks a bunch Engine Nut!

Are these 2007 curves? Any marked difference (relatively speaking) between the 06 MCX vs. the 07 MCX with cats?

I did as Chuck requested and never showed them...just goes to show what you can do when you work there.

Perhaps someone will now be able to add an LY6 - MCX - L18 comparison to the FAQ thread - sweet!

2006 with ETX and 2007 MCX with ETX CAT curves are right on top of each other.
