So I've been Internet shopping (stalking according to my wife) used x45's for about a year. Would really like to be in an 07 - 09 in order to get the newer tower design but would be open to the right 05-06. Previously, I had written off the MCX, But I can't believe the high prices even on boats on boats with high hours. Unless the seller is nonsensical, the MCX boats are a little cheaper. I read plenty of posts from the "MCX is under powered for that large a boat" and the "I've never had enough power" guys but this an open call for somone with a MCX 45 to say its either bad or good. I will be at say 800 to 1300 altitude and would eventually like to carry extra ballast for both boarding and surfing. Thanks.

Can't speak for altitude but MCX is just fine in my 2008. Others will disagree. 5 blade from OJ helps. I surf with a lot of ballast.

You'll be fine....I just sold my 2008 with MCX and used it at 6000 ft and was always fine!

I think it would be fine, yes. But, if there are options with bigger motors, I'd certainly go that route.

My 07' X45 has the 330 hp crusader (PCM) saltwater series engine, As far as wake surfing goes pretty much any weight/extra ballast has never been an issue. I use stock ballast and I throw a 700 pounder in the back locker and have had my 1100 pound sack in the middle with 12 people in the boat. I've also had 18 people plus the stock ballast and the 700 partially filled in back with no issue.
The only time I wish I had more power is when I have 10-12 or more peeps I have to start draining the rear tanks to get up on plane for wake boarding speeds. These x45's definitely need some extra weight in the front.
IMO it's not a deal breaker, but a little more power would be nice. Great boat with one of the best layouts fore sure. Good luck.

The 800-1300 altitude won't make a difference in performance. Test drive the boat with MCX and see if meets your needs for performance. Everyone has a different view on performance so it really depends on what you like/want. Good luck and let us know what you decide to buy.

I would make sure that any boat that you buy with an MCX is perfect because that would be the only way to justify a purchase of a boat with that small of a motor. I have the 6.2 in my x45 and I don't ever have any problems. Before we purchased our we test drive one with the 5.7 illmor and the thing struggled even with the wake plates. Sure you could change the prop and run higher RPMS constantly and burn twice as much fuel. The x45 is a big heavy boat and that MCX will always be working hard espically with more than stock ballast and a few people in the boat. Personally the bigger the engine better. I wanted the 7.4 but they don't make it in a salt water series. I wouldn't ever buy a boat underpowered again as I have made that mistake in the first boat purchase I made. Just my .02

Good info. Keep it coming. Interesting point about the fuel consumption with the right prop to get the 5.7 going. Is it just a time to plane problem or situations where you cant get to plane?

Changing the prop will help with holeshot and the heavy load but it will usually raise your RPMs during normal wakeboarding speed and you will also lose top speed. If it was me I would have to be getting an amazing deal on and X45 with an MCX in order to buy it and then I would still have to think long and hard about it.

Like many have said I'm sure it will be ok with a new prop. However if you have to dump ballast to get on plane then no the engine is not good for the boat. Also you got to take into account the amount of stress that puts on the engine. I would imagine your gonna burn twice as much gas as you would with a 6.2L as the engine is going to pushing nearly a 6000lbs when loaded down.

Another thing to think about is resale. A big boat with a small engine is going to limit potiential buyers because a boater with years behind the wheel is going to be thinking the same way that you can never have to much power.

Sounds like the mcx will do the job, but with effort and added costs. So it would come down to 2 questions. 1. How much more will one with a larger motor cost and can I afford it, (if I can afford it I go bigger motor) and 2. How long do I plan to keep it, and when time for selling/ trading how much do I think the price and desirability go down. Definitely lake test before buying and see if it really works for you.

Have the 07 X-45 with the MCX. I have no issue with it. I have 750's over stock in back and 2 250's over the KGB in front. It has plenty of power for this setup. I hate under powered tools, cars and boats I would not put the MCX any where in that category.

Have you given a 45 with the LY6 or L18 in it?

Sounds like those with the MCX are happy. Sure everyone would take more power but the fact that most people with that boat and that motor are fine is encouraging for you.

Prop it a little more aggressive and spend the extra $$ on ballast and stereo.

That's kind of like marrying the first girl that kisses you... Chances are, there are beret options out there. If the MCX is the ONLY option you have, that's one thing.


There is absolutely no doubt that in the 45, the bigger the preplant, the better. You will use a heck of a lot more fuel under load with the MCX, especially if your going to sac it out. The difference in fuel consumption between the LY6 and the L18 is substantial under the same conditions and weight, the MCX is going to be markedly worse.

I don't think anyone is arguing Scott, I was just pointing out that the people with the MCX that own the X45 appear to be happy even though by your account they have "settled" on the first girl to kiss themů:)

I thought that was funny. I've said there is nothing wrong with the MCX, but of you're in the market for a big boat like the 45, and you have options that have more power then the 5.7, and you test drive them, I'd be surprised if people opted for the MCX over the other options available.

I would agree with that statement ^^^.

I have a 2005 X45 that I would consider selling. I bought the boat last year and I find it too big for my taste. It was a one-owner boat, so I am the second owner. Everything is working, the tower has been completely rebuilt professionally with welds in the right places to prevent stress cracks that were common with that design. The boat has 360 hours. I had to buy a trailer when I bought the boat, so the trailer has less than a thousand miles on it, dual axle, bought at the Mastercraft dealer. If you are interested, tell me what price you have in mind to make it attractive for both of us. I have not advertised it as I was thinking about getting a smaller boat. By the way, it is red/white with matching trailer (white). The boat has never been in salt water, it spent its life in Fort Worth and now on Lake Conroe north of Houston.
