Looking at getting a new star and wondering how well the 6.2 performs vs the 7.4. All you owners with experience, please let me know. We ride in approx 3500 foot altitude.

I had the 7.4l. If I had it to do all over again, I would still go with the 7.4l. It is an awesome engine. With that said, I am sure the 6.2 has enough power for the XStar in most circumstances.

Thanks. If you ad a full boat and additional ballast, I know the 7.4 will pull it, but will the 6.2 get out of the hole? Trying to save a little gas too....

Trying to save a little gas and "X-star, additional Ballast & 7.4" should probably not be in the same sentence.

I know on my X-30, the 6.0 gets us up no problem, even with 3500lbs of ballast so I would bet the 6.2 would be more than enough for most people in the Xstar. How much ballast do you plan to run?

I believe the upcharge for the 7.4 is going to be more of a factor than the additional gas...

I don't know anyone ever that has said, "I wish I had less power". If it's in the budget, go for it.

That said unless going 3,000+ lbs in ballast most people seemed to be happy with the old 320-350 hp 5.7L. I'm sure the 6.2 is great even for quite a lot of ballast. I'm guessing the price delta from 6.2 to 7.4L on a new x-star is probably almost as much as my whole boat cost. You'll get a little bit of that back on resale but probably less than 1/2 of the up charge.

Agreed. No one should buy a Star, or any towboat for that matter, with expectations of good fuel usage. That being said, there are noticable fuel savings with the bigger engine under similar load.

Those are great replies. I agree that xstar, ballast, big engine, absolutely don't go well together. That made me laugh.

Sounds like the 6.2 will do what I need it to.

On a different note, I heard the new G2 system retrofit will be approx 9000. Wow!!! Just to install a couple of plates and add software????

from the information I have read the 7.4 is a couple hundred pounds lighter and is actually more fuel efficient than the 6.2

You heard wrong. The 6.2l is the lighter engine than all the others and typically has a lot better fuel economy than the 5.7 and 6.0l. I don't know if it is better on fuel than the 7.4 because I haven't had both engines in the same boat yet, but I am thinking the 7.4 drinks more gas unless it is ballasted beyond the 6.2s capability.

As a 7.4L owner, whose sole purpose is to increase their carbon footprint...I can tell you that the big girl is thirsty...but start her up & hear her growl...completely worth it.

Btw, G2 surf tabs being installed in the next couple weeks...will let you know what it can do.

Well it has been tested by mastercraft and word has gotten out that it makes a "sick" wave/wake.

my buddy's xstar when weighted down takes forever getting out of the hole with the 6.0 L and is always running at 4k rpms. I would go with the 7.4.

It was explained to me like this by the guys at the factory: The X Star is MC's flagship boat, the G23 and Malibu competitors to Star have built in great surf waves...with more and more people doing both, they had to have their Flagship boat be a great surf boat as well.

I would be absolutely shocked if this not a really good surf wave, if not they would have been better off not to come out with it at all...they do not want the press of the g23 or surfgate system blowing the doors off the Gen2 on the Star. (or at least if I ran the company I wouldn't let that happen)

just my 0.02 cents.

The 6.2 will get the job done but get the 7.4. You will never sit in your boat after a day of riding and say to yourself, "Hmmm, I should have purchased the smaller engine with less power." :D

We have a X-55 with a 6.2 even running close to 3400 lbs of ballast, plus five onboard. The boat will pull your arms off with the stock prop. Drive one loaded up, the 6.2 is a impressive motor.

Plus it is easy on fuel.
