I tested the ACME 1235 today, December 21, "the end of the world" day, 2012

I tested OJ Core and OJ Cinco on March 21, 2012

I tested the ACME 2419 (15 x 12 x 0.075) on April 26, 2013

I tested the ACME 2315 on July 12, 2013

Had a few guys on my boat yesterday who have a lot of experience and knowledge about wakeboarding, boats, props and the Axis line. Later next week sometime I will post pictures of the wake as requested by some, as well as the gopro video of the guages that I took. This is a comparison of the OJ Core prop that I was running last year with the new OJ Cinco. The OJ core is the most aggressive prop for the axis and from what I have read, is very similar to one of the ACME 1615 (the more aggressive one).

March 21, 2012:

AXIS A22
335 w/ CAT
No Wedge
Full fuel tank
4 adults, 1 toddler
Air = 84 F
Water = 65 F
Water level range = 5’- 14’
Wind = 10 mph going down lake and up lake


OJ Core

No Ballast (650 lbs of lead, 400 bow, 250 center) tanks completely empty:

0-23 mph = 8.6 seconds (average of 3)
23 mph RPM = 3150 (24 mph RPM = 3350)
Top Speed = 35.5 mph
Clean wake slowest speed = 18 mph


Full Ballast [4000 lbs (1900 rear, 1800 front, 250 center plus gear) no wedge]

0-23 mph = 18.4 seconds (average of 3)
23 mph RPM = 3550
Top Speed = 35.2
Clean wake slowest speed = 22 mph


OJ Cinco

No Ballast (650 lbs of lead) front pnp and rear hard tanks not completely empty +/-200 lbs due to some water not completely drained

0-23 mph = 8.8 seconds (average of 2)
23 mph RPM = 2900
Top Speed = 43
Clean wake slowest speed = *19 mph


Full Ballast [4000 lbs (1900 rear, 1800 front, 250 center plus gear) no wedge]

0-23 mph = 20.9 seconds (average of 2)
23 mph RPM = 3300
Top Speed = 38
Clean wake slowest speed = 23 mph

* there was still some water in rear hard tanks and front pnp, possibly 200-300 lbs. I believe if it would have been completely dry like when the Core prop was tested, the clean wake speed would have been the same as the Core prop.


December 21, 2012
Air: 60
Water: 56
Water level: 8-19
No wind


ACME 1235 ( option as the "high altitude prop" when buying from dealer)

No Ballast (600 lbs of lead, full fuel -10 gallons?, 2 adults, 1 toddler, 350 lbs of lead on rear of floor to simulate the 2 other adults we had last test in similar positions on the boat. Tanks completely empty.

0-23 mph = 7.5 seconds (average of 3)
23 mph RPM = 3100
Top speed = 41 mph
Clean wake slowest speed = 18


Full Ballast 4000 lbs (1900 rear, 1800 front, 200 center) no wedge

0-23 mph = 14.7 seconds (average of 3)
23 mph RPM = 3500
Top speed = 39 mph
Clean wake slowest speed = 23


ACME 2419 (15 x 12 x 0.075)

No ballast (600 lbs of lead, full fuel, 4 adults, 1 toddler, ballast tanks completely dry)

0-23 mph = 7.4 seconds (same in 2 tries)
23 mph RPM = 3150
Top speed = 38 mph at 5200 RPM
Clean wake slowest speed = 18

Full Ballast 4000 lbs (1900 rear, 1800 front, 200 center) no wedge

0-23 mph = 13.8 seconds (average of 3)
23 mph RPM = 3500
Top speed = 37 mph at 5200 RPM
Clean wake slowest speed = 23 mph

ACME 2315 (15 x 12 x .105) *this is the only prop tested with 200lbs of bow lead taken out and moved back, made a HUGE difference with my cinco prop, so this prop conditions were slightly different than the rest of the props tested.

No Ballast (600 in lead, 4 adults, 1 toddler, and 200 lbs less in bow tips) no wedge

0-23 mph = 7.8 seconds (average of 2)
23 mph RPM = 3100
Top speed = 40 at 5200
Clean wake slowest speed = 18.8

Full ballast (200 lead in bow, 400 in cabin rear, 4 adults, 1 toddler, no wedge)

0-23 mph = 19 seconds
23 mph RPM = 3500
Top Speed = 39 at 5200
Clean wake slowest speed = 23

Other Notes by observers:

Cinco and ACME 1235 props are considerably quieter than the OJ CORE when throttle is wide open getting the boat to speed. ACME 2419 was surprisingly just as quiet as the ACME 1235. At speed, in boat noise was also noticeably quiter. We could hear each other talk without yelling. The faint whining of the v-drive was present with the Cinco, 1235, and 2419 but not with the Core. The engine exhaust noise could be heard with the Cinco, 2419, and 1235 but not the Core. The combination of the exhaust with the v-drive whine was a pleasant surprise with the Cinco as it was by far the quietest and smoothest.
There was absolutely no porpoising at any speed with any prop. The bow rise was considerably less with the Cinco compared to the Core, unknown with the 1235 or 2419. The Cinco “bit” harder during high speed sharp turns, felt smoother during small turns or adjustments, was smoother at every engine speed and boat speed, and was smoother during at-speed acceleration as compared to the CORE. Axis speed control had no problems holding speed with any prop, but the 2419 was probably the best of the 4 at holding speeds. The Cinco produced a cleaner wake with less prop wash, noted by all observers. Unknown how the 1235 or 2419 compares. The Cinco did feel like it would cavitate for a few prop revolutions during full hammer down acceleration from 0 mph. The 1235 would do it as well, just half as long, the CORE did not do it at all, and the 2419 was the smoothest when hammering down the throttle, no cavitation, no spinning, and not as much vibration as the CORE.
The Cinco performed well getting the loaded A22 up to speed, but the Core will pull a little bit more weight. I put the sumo 800 floor sack added with the Cinco and 1235. The Cinco BARELY got it up to speed with 3 people and 1 rider, but had to drain ballast to get it up. The 1235 could get that same set up on plane without draining ballast, but barely. (Will test the 2419 this week.)

We were both surprised by the results of the test. Tim was with me for all 4 prop tests and we are both loving both the ACME 1235 and 2419. We were surprised that the 1235 performed better than the CORE prop in ALL categories. Axis sells the "core" prop as an upgrade to the 1235, in my experience, it is not the case. Wakeprops.com has, what we both feel, the correct information. plus 1 upgrade cinco, plus 2 upgrade 1235, and plus 3 upgrade acme 2079 (have not tested this, would love to, but the numbers alone with the 12 pitch has got to be gnarly).

The only advantage the cinco has over the 1235 or 2419 is the top speed and engine RPMs and the difference is not much (2 mph's and 200 RPM's) the ACME 1235 pulled my weight very easily, was almost as quiet and smooth, and was faster to plane. Another thing is the 1235 and the 2419 are 4 blades, so my prop puller works. My Cinco is a 5 blade and I have to use a little heat on the hub and a hammer to get it off, not a huge deal, but is worth noting.

In my opinion, the ACME 1235 is the best all around prop of the 4 whether you are going to use stock ballast, stock plus plug n play, or slam out your boat up to 4600 lbs. If you go heavier, then you will want a motor upgrade or find a different prop. The Cinco is perfect if you run heavy, like to cruise at speed, ski, barefoot, or tube. The core has no use at all, imo (ACME, let me borrow a 2079 and the 2315 and 2313 please). If you are running 750's + in the rear, wedge, bow sack and additional weight, the 2419 will be a good prop. The next prop up is the 2315 with the next "cup" up at .105, then the 2313 with the .150 cup. The 2079 has the same cup and pitch as the 2315 but just 1/2" less diameter, so should be real close, maybe a little smoother.

2315 is a beast. We got up my new weight set up no problem, it took a bit of time, 19 seconds, but the Cinco could not get my new weight set up on plane without draining ballast for a minute first. So I am excited to throw some more weight at this thing and see what it can do.

Let me know if you have any questions that I this test did not answer.

Great write up! I was leaning towards the 1235, so that settles it then. Thanks!

I agree that the 1235 prop is the best prop for the Axis for all around riding/surfing. The 1235 came on my boat but I currently have the Cinco prop on it now but will be going back to the 1235. Personally I think the Cinco was noticeably quieter inside the boat than than the 1235 and less vibration as well. As noted in above posts, the Cinco had a less turbulent wake and less roost on the prop wash.

Main reason I'm going back to the 1235 is that when wakeboarding using the 1235 and the cruise, the cruise held nice and smooth even in pretty tight turns. When I went to the Cinco doing the same turns the cruise would pick up speed slightly then coming out of the turn it would return to desired speed.

AJ, i get to keep the 1235 for a few months and will do more testing (like throwing my 800 sumo floor sac in to see if i can get the 1235 to fail). When I have to give it back, I will put my cinco back on and maybe I will notice the noise difference. I did not notice the 1235 being louder because it has been atleast a week since I took my boat out with the cinco... I really wish I could have tested all 3 props the same day to make it as fair as possible.

One thing I noticed is that the 1235 did not hold speed any better than the cinco. I know with my cinco that the speed would go up or down by about 0.3 mph faster or slower than the set speed, depending on who the rider was and how hard they cut. This is with full ballast. The 1235 did the same thing. When I add the 800 floor sac, the speed varies a bit more with the cinco, I will see if it holds better with the 1235.

So far I am impressed and if I were you, I would use the cinco as a back up prop.

John, I plan on keeping the Cinco prop when I switch. I found a Walter prop puller on Craigslist for $100 that the guy only used once. It can remove a 5 blade prop...it is also a $475 prop puller new.

wow. that is a fantastic deal. I looked into that too, crazy expensive. I have pulled my cinco twice in the last 2 weeks. Just used a MAPP gas torch on the hub for a few minutes, rubber mallet through a 2x2 on the hub a few times and she slid right off. This week I removed it again to put on the 1235 and after a couple minutes of heat, it slid off without the hammer.

Not ideal, but once i give the 1235 back, I will put on the cinco and keep it on until i fold over all the blades...

Just curious. Is there a reason why you did not test the 2315? I am running more ballast than you and more people on the boat so the 1237 which is the same as the 1235 did not work for me at all. Went to the 1615 and that still did not work. I ended up gettting ahold of the last 1615-112M and that thing was killer. It pulled all of my weight out of the water that I wanted and with very little trouble. This year when the 2315 came out I was all over it. I wouldn't say it was a lot better than the 1615-112M but I did notice a little bit of difference for the better and the bonus on that is they still make this prop. Just my opinion but if you think the 1235 is the prop for you I think the 2315 would blow you away.
