Supras with Acme prop 14x14.25-150 cup

I have an oj 13.7x17.5 and it's sluggish when we fill the sac's. Jim at Acme recomended a Acme part #1847. It is a 14x14.25 with a 150 cup. He said it would be night and day difference. More torque less fuel useage and a small drop mph on the top end. Any one else have this prop?

I do - it's what Supra bills as the "Wakeboard Prop"

Never had anything but this one tho.

I know others who switch from your prop to mine when loading the boat, and keep doing so.

Like Todd, it's the "wakeboard prop" supra sells as an upgrade. Great prop. If you wanna save yourself some cash ( till next season) take your stock prop over to Bauman's and have them pitch it down 2 degrees. I usually do this to my stock prop as backup.

Just had the 14x14 with a 105? cup put on my 89' supra..Its like dropping a Saleen super charger on it. It just blasts out of the water now. DO IT! Who cares about top speed. I hardly ever take mine over 30 mph anymore. Jet

our 21 v has the cnc wakeboard prop which I assume is what your talking about ....the boat still goes 42 mph.............and pulls out with 2300lbs and 4-8 peeps like nothing.

The Supra wakeboard prop is a OJ XMP 14.25 X 14. Acme suppossedly makes a good prop also...

oops..mine was the ACME. The larger the prop and the more cup you have, turns it into a stump puller. Ha ha ha! Jet

we have the OJ "wakeboard prop" happy medium to the ACME 1235. Way more torque than stock but not as much top end loss.

The 1235 has a 105 cup. This 1847 has a 150 cup. The oj Supra wake board prop either a 90 cup or a 105 cup.

Isn't the rumor that the Acme 1235 prop has less vibration/cavitation in the 2k-3k rpm range vs the OJ 466? I've read this on several forums.

Speaking of the performance props for supra. Anybody know the cheapest place to get one of these from? I am planning on buying in the off season for my santera.

Cheapest I have found was $460.00 for this prop. Direct from Acme is $509.00

Like Adam said, wait untill you ding your stock prop and have it re-pitched...it will be nite and day difference. It will pull close to the OJ or ACME.

No reason to blow $500 on a new prop unless you just want a spare.

Yeah I woildnt mind having a spare and the current one I have is a stainless. Wanting to get away from that.

Aaron where did you find the 1235 Acme for $460 at?

It's the 1847 and it is gona be like $430.00 from a friend that works at a dealer. I think there is a vendor on planet nautique that sells them for $460.00.

I have an 07 Launch 21V that came with the wakeboard prop from OJ (14.25X14 Cup .090). With about 3000 lbs of ballast in the boat to get on plain and up to wakeboarding speed of 24.6 mph it would take approx 20 seconds. Just switched to the Acme 1245 (14.5X14.25 Cup .105) and the time it took to get on plain and up to speed was approx 7 seconds.

I got my prop from Nettleprops.com

Do you mean the 1235 prop? I can't find a 1245 prop and those prop dimensions match the 1235.

Yeah i meant the 1235.

We offer a new 14.25 X 14.5 LC 1 1/8" 4-blade for the Supra and Moomba boats. This prop tested better than our current 14.25 X 14 as well as the other props mentioned from the the other prop builder. Testing was done at the factory. We also offer 14.75 x 13 lc 1 1/8" 4-BLADE, this prop was used to pull the 08' and 09' Worlds.

So it seems the acme would be cheaper than the OJ?

J.brenner I sent you a pm. Just let me know.

You want the 1273

Which one is the 1273?

Eric hey I'm interested in that new prop. I've got a 2k9 Supra Launch 21v with a stock OJ 13.7 x 17.5. It's horrible with full ballast and 6 peeps. Sometimes won't even get on plain. I was thinking of the Acme 1235. Don't really care about my top end, I never go much faster then 30-35 anyways. Would you recommend this new prop over the 1235? I want something that will pull a full load with no problem.

Also what kind of performance could I expect out of these 2 props? Same dimension just different cup sizes.

1235 -14.50 14.25 .105 cup 4 1 1/8" LH

1273- 14.50 14.25 .150 cup 4 1 1/8" LH

good questions that i want to know also

Chad - The new prop would work much better than the stock 13.7 X 17.5. Our new 14.25 X 14.5 performed better than the 1235. The performance was tracked using a radar gun connected to a Stalker program. Not blowing smoke here guys, the prop works better.

To the point that OJ's are thick and soft...I would agree that our props are a bit heavier than the other but would disagree they are softer. The OJ is thicker to allow for longer life, can actually be repaired and will not bend as easily. I would not agree the other props are brittle, they are thin and bend easy. Tougher to repair for sure because they are thin.

Cup - Cup is simply a way to control RPM relative to pitch. More cup = less RPM. So you can expect less RPM from a prop with more cup.

Rumor that the other prop has less vibration/caviation...false. While both the OJ and the other prop make noise on ONE particular boat model, the noise is not just a prop issue.

We both make good products that perform well. Not here to bash the other guys stuff, sometimes it gets tough to see the reality through all the smoke.

A radar gun??? Most of us ride about 21-24 mph. I think most people are not real concerned with top speed. You should be comparing how quick it comes out of the hole, time to get on plane,thrust, torque. How do those things compare to other props and how did you test them?

Eric thanks for the very informative post. When you said you tracked the performance with a radar gun and it performed better in which area were you talking about. As you can tell almost everyone here is willing to sacrafice top end for more torque on the bottom. How much ballast will this prop support while still being able to perform. How much ballast was your boat tested with? Any info you spare will be greatly appreciated.

The test boat was fully loaded with the factory ballast. All props were tested with the same load. Our new 14.25 X 14.5 was best on acceleration times. As with you, low end power while loaded was the main concern.

Eric - Could you please post the information and results from your test?

Just out of curiousity since you brought up vibration/caviation, what specs and guidelines do you follow when balancing your props?

Eric also what size cup is on your new prop?

The test data is something we cannot post. Testing was done with the boat manufacturer using their equipment.

Was responding to the claim our propellers cavitate and or vibrate more than another prop. All our propellers are static balanced. The guideline is, they don't go in the box unless they are perfectly balanced. That task is handled by an employee of ours with over 35 years of experience.

What ISO specs are you following?

Chad - Standard cupping is .110

We do not have ISO spec'd propellers.

Why are you static balancing instead of dynamic balancing?

Because it is accurate as dynamic and when you have to produce thousands of propellers, less time consuming. You in the business sack?

I had a OJ 468 on my BU and damaged it beyond repair. I went with a 1235 this time and I must say I like the OJ better. It had better holeshot and I notice now with the 1235, I over rev and loss about 3 mph top speed.

I am not in the prop business but i am in the vibration analysis industry.

I have to say that in some cases that technology can improve quality.

Agree, it can. That is why all our master patterns are CNC machined, our hand finished props as well. People are also an important component of the quality process. While a dynamically balance prop may be perceived as better, there still is a person that is responsible for removing the material and doing the job right, whether it is balanced static or dynamic.

I just went through the gammet of changes on my 24v with the Indmar 325hp. I had the older version, non-cnc'ed, 14x14.25 OJ prop on my boat that came from the facotory, worked great loaded or unlaoded had no complants. Unfortantly I found a submurged tree and sheered off all the blades down to the nub.
The dealer mistakenly installed the 13.7x17.75 when the changed out the under water gear. I could tell a diffrence in the attitude of the boat while ideling and just pulling out of the no wake zones, it was terrible. Pulling up somone with the boat fully loaded was a joke, took what felt like 300 yards to get on plane and would hit the rev limiter too quick, it even strugled pulling a 100lb kid on a tube, never had that before.
I called the dealer and they got me the new CNC'ed 14x14.25 OJ, it is a night and day diffrence the boat even seems smoother, of course that could just be me.
The change is dramtic and worth the money.

Well I got my prop Saturday (Acme 1847)14x14.25 with 150 cup and put it on today. It took a whole 15 minutes. I did not even need a prop puller and did not have to heat it either. I can't wait to try it out.

Eric,

I've got a 2006 Moomba Mobius and I run at sea level and a moderate amt of ballast (1300 lbs) for wakeboarding, usually with about 6 people on board. I don't foresee running any more ballast than that. I was told by my dealer that the 13.75x15.75 should be fine and that the 14.25x14 would probably be overkill for my purposes. What are your thoughts?

With 1300#'s of ballast and 7 people on stock prop, it takes forever to get on plane pulling a wakeboarder so I'm looking for a prop change.

Thanks.

Sounds like the new 14.25 X 14.5 would be the cure. If you are struggling to get on plane then the prop change would make the difference.

Al C,
Your set up is about like mine. When I called Acme they recomended the 1847. They said I might loose 3mph on the top end but I would have moore use of the rpm range. They said it would be night and day difference and if I did not like it send back. Tell them what I did not like and they would send me a different one.

Aaron - We also offer a 14 X 14.5 LC 1 1/8" 4-blade you are welcome to try along with the 14.25 X 14.5 Lc 1 1/8" 4-blade.

Eric,

So you don't think the 13.75x15.75 would be enough?

Eric, I'm running the 13.5 x 17.5 prop in my 22 sunsport right now. I'm running between 1700-2000lbs of ballast when I ride. It takes forever to plane and I realize I'm probably loosing a lot of fuel efficiency with this prop. What prop would you suggest to use?? How much will the prop cost around?

Al - I have tested the 13.75 X 15.75 and found the 14.25 X 14.5 to run better. The reason is the diameter being larger. That is why we created the larger diameter lower pitch props a few years ago, the larger diameter helps with acceleration. Better than just reducing pitch.

Andrew - Our 14.25 X 14.5 would be a good fit. You can give me a call - 800-359-9730- for pricing info.

Just wondering what is the cost on a 14x14.25 with a 150cup and will you exchange them with in 30 days like Acme?

Eric, I have a 03 launch ssv. Would it be the same prop as for Andrew?

We have always offered a full refund of the price of the propeller or the option to re-work or change sizes if the propeller does not perform.

Tony - Yes, the 14.25 X 14.5 would work well.

For pricing please give me a call. 800-359-9730

What would one cost me?

Aaron - PM sent

Eric, I would like to know also

I would be interested in a pm on the price of the supra prop upgrade. I have the 13x17 and it takes forever to pull up a boarder with the bags loaded down..
says you exchange if it does not work, what about buying in the winter and not putting in the water until spring??

Whoops

Scott

When I got mine from Acme they said that would not be a problem on the install during winter and not testing till Summer.

Scott - Would not be a problem. PM on the way

thanks all.

going to do some hard research as it looks like both oj and acme make a good product

Put mine on today! OJ. Yes I took the pic before i put the cotter pin back in. Little concerned about trailer clearance. That's a small 5mm socket for size comparison.

Which prop did you go with?

Was that from the the guy I sent you the pm about?
I can't wait to test mine out.

14.25X14. Yup Aaron, thanks again!

Glad to see some one got a sweet deal that came just a little to late for me. I did get a smokin deal on my Acme but the price on that Oj was much better.

Took mine out today and I am happy to report there were no clearance issues with the trailer. I didn't feel the "feels like a completely different boat, best upgrade I have ever done" but I think the butt dino did register a change. It seemed a little more responsive off the start and maybe my expectations were just a little to high. Crazy side note, the prop change colors, notice it when I pulled the boat out. Not dramatically but it is def not the same color as the picture above any more. I was running a 13X16 SS prop before.

Gonna try and take another pic for color comparison. Looks pretty dang different. Anybody looking for a blinged out SS 13X16 1/1/8th prop LOL?
