Last weekend my son and I wanted to enlarge the wake size so we filled both the port and starboard rear lockers with 750 fat sacs. So with full ballast 1K lbs, 1500 lbs of extra at the furthest point aft and about 800lbs of people sitting rear and mid boat, the 5.7 just couldn't get the weight moving past 14-15 mph. Even when I shifted people weight it just couldn't pull the extra. I was pretty disappointed, but not sure if my expectations were too much.

Has anyone had a similiar experience with the 5.7?


The next morning we took one 750 fat sac in the rear seat with full stock ballast and it pulled just fine.

You might consider changing propellers from the 14.75 X 15.5 to something more agressive on the low end, 14.25 X 14.5 or 14.25 X 14.

Also move some weight forward.

I'll look into that.

yeah, maybe just keep the sacs in the rear seats and I think it'll go that way. I also could have put the 370 tube sac in the middle up towards the front to balence it out. Just looking for others to give suggestions on set ups they've used in the past

With a 5.7 and even some of the bigger engines, you need weight up front to help get the boat on plane if you are running that much extra ballast in the back of the boat. If you will be regularly adding this much weight I'd switch to the 14.25 x 14.

Wondering.....because I have never been in a newer MC X30 how is the wake with Stock ballast? I recently took some rides in new boats from a few other companies and the wake with stock ballast on these was really good if not great IMO.

I have the same boat with the same motor and I have 750's in the rear. You need three things when lugging all that weight around. 1st is you NEED the wake prop. No question here. Second is you need to either move people up front or add more weight up front. It's just too much rear weight versus front weight without doing this (2200 in the rear and 400 up front). Third is you need to start out with the plate all the way down, then when you are past 15mph, raise it back up. Try these few thigns and it will pull all that weight around no problem. Keep in mind, 4500 boat + stock 1000 + extra 1500 + 800= 8k in weight almost all rear loaded.

stock ballast is not tall but pretty long, everyone in my family learned to go wireless on stock ballast but whenever I started trying to move around a lot more (6 ft 190lbs) I could lose the pocket very easily. with a single 750 fat sac in the rear locker it got a lot taller. Then I kept adding until it's as good as I see out on the lake we spend our time on.

thanks for the feedback 501. I'll get the prop. I didn't get the plate on the boat, I'll check into getting it installed now. But with us not skiing much it seemed unnecessary at the time. And I'll move weight forward and see

That sounds like an incredible amount of weight. I would try with a 60%40% ratio front to back and work out from there but go both directions you might be surprised. I'm at about 50/50 and I move a few hundred pounds here or there and it makes a difference.

More weight up front

I think these few things will make a HUGE difference with all that extra weight. I highly recommend the wake plate, I love the versatility of it.

I will say that with the stock 1000 and the extra 1500 in the rear and about 200 up front, the wakeboard wake is bananas and you can ride it with all this weight as slow as 21 which is unheard of for 23+ foot boats with that much weight.

Here's a link to a thread I started about how different props change the launch characteristics of the 5.7 Ilmor. We tested with an '11 X25 but it should translate to your boat as well.

Guys, I'm about to purchase a new 2013 x-30 with the 6.0L.

Should I go the 6.2L or is the 6.0L sufficient for our typical needs which is:

Light wake boarding
Surfing

And we usually only have 3 of us or when friends are over we are looking at 6 adults and 4 young kids!

Should the 6.0 be enough?

Should I get the high altitude prop?

Thanks

High Alt prop and the 5.7 is enough, honestly. 6.0 will be great.

Is the high altitude prop a ACME 1235 or does anyone know?

Thanks for the quick response

I believe that is the same prop. I wouldn't run this boat (or any other wake boat) without the high alt prop.

Yesterday we loaded up the X-30 and took a friend wakeboarding who is one of the top Riders in canada. Here is an Iphone pic of him doing a Toeside batwing. This is on the way up! Wake was money yesterday even though the water conditions weren't. Thats another thing I have found, when the water isn't glass the X-30 wake is still clean and doesn't wash out as bad as a steep wake will.

Get the 6.2L. If you don't, then you will always regret it....I know the 6.0L is enough for that boat but the first day when there is not quite enough juice you'll be wishing...
