View Full Version : MCX vs. LY6 Engines in a 2008 X-2

Hey y'all! I'm getting close to purchasing a used 2008 X-2. There are a number of them in the northwest region that I'm looking at. All beautiful, well taken care of, and with very low or relatively low hours. Most of them have the MCX engine but one just popped up with the LY6. This seems a rarity to me. The boat with the LY6 has pretty much every option and an attitude adjustment plate, which I want for the family slalom skier and none of the other boats have. I know I can add this to the other boats, but it's about $2500. Other than the 50 extra horsepower, what's the benefit of the LY6? Is there any significant GPH difference between them? Those of you that have had experience with an X-2 (or X-14 or similar) with both, what are your thoughts? The only downside to the X-2 with the LY6 engine is an extra 5 hour drive on top of the 3-5 hours I would already have to drive to pick up the boat. Doable on a weekend, but that's a long drive. FYI, no one in the family is a barefooter, and no one has barefooting aspirations. Okay now, discuss!

If you were running the boat at high alt I'd say go for the 6.0. Here in WA the 5.7 will push the boat with authority. The5.7 is a simpler more proven engine too.
That said if the LY6 boat is better in any other way, I'd go for it.

I've got the LY6 and my friend has the MCX....same boat. Although we haven't done a real comparison, it seems as though mine burns through the fuel a bit faster. After winterizing both, I prefer working on the LY6.

If mine did not come with the LY6 I'm sure I would be just as happy with the performance of the MCX. However, if you are loading it up with weight you might want those 50 extra pony's to help out.

cant imagine what i would do with 50 more hp in mine. The mcx is just right for what we do, slalom, WB, surf. Check to see what type muffler you have, tips or silentmaster. Makes a difference if you want to hold a conversation at certain RPMs. I do not have the silentmaster and wish i did due to excessive noise. The upside is the hot rod type folks love the sound of my boat.

didn't even know the LY6 was offered in an X2...
IMO i've been on plenty of 07+ X2's and the MCX is plenty for that boat, even when weighted with 11 people... MCX has no problem

I owned a 2006 X2 with the MCX. I am 6'1 230lbs and it dragged the crap out of me when i was skiing:mad:. That is why we sold it and got the X14V. If i had to do it again go for More HP. you can never have enough. The LY6 is a proven engine and has been around for a long time. Attitude plate is a must as well. As far as your drive is concerned hopefully you will only do it once!!:D When I order my new boat I will order the 6.0 or the 6.2

Ugh, so I'm seeing (in the TT archive) around 10 gph for the LY6 vs. about 5 gph for the MCX. That's a huge difference. I'll ask the seller if he knows what he's getting though. That quoted value for the LY6 is on a bigger boat. On a small boat like the X-2 it might need less.

What's the price difference between the boats?

I've not begun serious negotiations yet. That said the difference in price looks to be negligible.

Im 6'2" 250 lbs and my 08 X2 with the MCX and my buddies 06 with the MCX have no problem getting me up.As far as fuel economy I think the X2 is only about 700 lbs lighter than an X-Star so it would be a negligible difference.I know guys with river boats who went to the 6.0 on their new boats and wish they had their 5.7s again due to fuel consumption.

Didn't even know an ly6 was an x2 option. I think that would be an awesome setup.



On a side note...... how this is moved to maintainence and refurbishing is beyond me. This is a great topic I am sure no one will ever come across or look here for.

I guess because of the "engine" discussion...

Yeah, the topic move was kind of annoying. This thread has nothing to do with maintenance.

I now check out the Engine and Electrical subforums in addition to General Discussion since most of the stuff I like to look at has ended up in those two spots.
