View Full Version : Thoughts on New Prop for 2013 X-30?

I have a 2013 X-30 with the 5.7 Indmar. It has the stock hard tanks plus Fly-Hi 750#s in each of the rear compartments. We use it to surf, board and ski. In a perfect world, we would have gone with at least the 6.0 engine, but we picked the boat up as a dealer demo with 11 hours on it last summer for a great price. It's been an awesome boat for us in all respects, but we do miss the initial hole shot from our 2007 X-2 with the MCX when getting up on slalom.

It came with an OJ Prop, 14.75 x 15.5. After 20+ years of incident-free boating, I dinged it pretty good on an unmarked boulder last weekend. All of the blades have a bit of damage, but the rudder and shaft appear unaffected, and the boat performs exactly as before (no extra vibrations, cavitation, etc). That being said, with my MCOCD in overdrive I'm considering using this as an opportunity to re-prop the boat with something that perhaps could deliver a better hole shot without completely cratering top end and, more importantly, fuel economy. I would be willing, however, to trade some of each for a noticeable improvement in initial hole shot.

Anyone fellow X-30 owners out there with thoughts on whether a new prop would address these issues and, if so, what brand/size to go with would be much appreciated!

That is a great question......

I too have the 5.7 and would like to know if anyone has tried a different prop?

ACME 2243. Our GM is religious when it comes to props and prop testing.

Acme recommended the 2197 to me (14.5 x 12)

Anyone know what the stock prop is on the 14 X30? I would like to get the RPMs down a little if poss! We mostly surf with ballast and the kids wakeboard or kneeboard with ballast empty.

I started with the stock 14.5x14.25 hight alt prop and it was great. I wanted a spare so I ordered an Acme 15x12 and I'm totally happy with it. While the boat isn't a rocketship (top speed is around 38), no matter what the weight it gets on plane and up to speed. If I still had my 5.7 I would definitely have this prop. It also decreased my rpms while riding from the stock high alt prop, so we use less fuel.

You mean the 14x12? Like JD posted?

Nope, the 15x12 (Acme 2305). It's a beast. As you may know the X30 creates the best wakeboard wake with most of the weight in the rear, and the more the better. With this prop it doesn't matter how much extra rear weight you have.

If I spent a lot of time cruising at higher speeds or skiing I wpuldnt have this prop, but if you like a huge wake and surf wave, this prop is where it's at.

As 501s said the 15 is going to be a little more aggressive than the 2197. Same Pitch but an extra .5" diameter. I just don't know if I need a 15" and we still cruise from time to time to the 2197 is what I will probably order. You have 30 days regardless if you don't like it so try a few out!

I have the ACME 2241 and it's great.

I am also considering re-propping to improve the hole-shot. Our X30 also struggles with 750ís full in the back with 4-5 passengers. I had a conversation with the folks at ACME and they recommended 2305 - 15" x 12" for a heavy X30. As indicated by many give up some on top end and some from fuel mileage. I know from experience when I switched to 14.25 x 14.5 on the X1 it was a night and day difference. Folks at ACME telling me; this will be as good of a performance up grade. Anyone else with X30 using the 2305 besides 501?

I used an acme 1285 and it worked like a charm.

My stock prop is a 14.5x17.5. I can't imagine the hole shot I would have with a 15x12! (Big engine problems):D

isnt it crazy that virtually all of us has been recommended a different prop for the same boat??

That's what I was thinking!

I have a 1285 and the upgrade to the 2305 was huge when carrying a LOT of weight. It's lowered my time to plane while increasing fuel mileage but reduced the top speed a bit. For what we do this was as big as an upgrade as going from the 5.7 to the 6.0. If I had the 5.7 again and was weighting it I would definitley have the 2305.

The variety of well informed opinions on this board make it an invaluable resource to us MC owners. As the OP, I wanted to fill you all in on what I learned from talking to Greg at ACME last week (by the way, good guy and really helpful). In a nutshell, he suggested a number of props that he felt would improve the performance of my X-30, depending on what I was trying to achieve. It's a good sign that he -- unprompted -- suggested the same 4 or 5 props that have been referenced -- the 2305 and 2197 for hard core surfers/boarders that like to add a lot of weight but don't need the higher top speeds associated with higher speed cruising and skiiing, or the 2243, 2241, and 1285 (all 14.25 pitch) that would provide greater punch out of the hole as compared to my stock 14.75 x 15.5 prop, but would not sacrifice quite as much at the other end.

Since I'm running the 5.7 Ilmor, keeping the rpms manageable was also an issue for me (as compared to those running the larger displacement engines), so ultimately I ordered the ACME 2241 (15 x 14.25) and should have it tomorrow. According to one rule of thumb, I should only see about a 250 rpm increase across the board at equivalent speeds. (Dropping all the way to the 2305 and its 12" pitch might have bumped my rpms up approx 700, which is more than I wanted to go).

I'll have it on this weekend and will post a follow-up on real world performance in case anyone's interested.

501 Are you currently running the 2305? What is your 500 lbs led distribution? I take it you had a 12 X30 with 5.7?
Thanks!

Yes, currently I have the 2305 And I had a 2012 x30 with the 5.7 and now have a 2013 with the 6.0.

I have the lead spread out in the boat with 200 up front, 150 drivers side under the cooler and 250 passenger side in the coffin storage.
