Some of you may have read my post about damaging my prop at the boat ramp a couple of weeks ago. I just ran my 80' SN with a new Acme 540 today. I had an OJ 4 blade on it and thought I had good merchandise. The dealer told me OJ was the way to go as far as replacement goes...probably because they don't sell Acme's...after reading Keith's thread on the 540 and doing further research that's what I went with and what a huge difference in performance it made! I lost maybe 1-2 mph on top end(still does 42-43)but out of the hole it puts the OJ to shame. If anyone is considering a new prop, give the Acme a try - if you don't like it, you can send it back. That's my .02 worth. ------------- Heath |

Heath...that seems odd that you would lose any top end? You should have seen a little gain with the 540. Glad you like it! ------------- stang Face plants are not that funny when it's you face! http://www.correctcraftfan.com/diaries/images/3720/photo1.jpg" rel="nofollow - The Super Air |

.. I should have clarified....I did have 2 pa$$engers when I checked the speed. Before it seemed like it would do 45-46, now just under that, but I still can't get over the hole shot. ------------- Heath |

I gained 3 MPH with my new ACME 540. I had the OJ, 4 blade before. The ACME 540 is great at low and high end. Some serious bite that thing has!

I was using an acme 540 and I switched to an Acme 208 4 bld. I like the wake better with the 4 blade prop. The performance is about the same, real good! ------------- VT. Nautique |

I've got the 1.23 to 1 tranny on my '95. Looking up OJ and ACME prop guides, it seems that the OJ 3-blade #428 13x15.5 and the ACME 3-blade #612 12.5x15.25 are recommended. What is the ACME #470 and should it be the one to go with ? ------------- Living outside the wake http://www.correctcraftfan.com/diaries/details.asp?ID=1525 - 95GT-40SNOB |

The 612 isnt in production anymore. Supposedly the 470 (12.5x15 3-blade) outperformed it. I was very happy with mine (before I bent it). I tested it back to back against the Acme 422 (12.5x15.5 4-blade) on 2 different boats and the 470 is a better prop (though it turns 180-200 more RPM).
The OJ 428 looks like its a 4-blade according to their website. My guess is that its comparable to the 422, but the 3-blade should be a better performer. ------------- |

tr, thanks for the info! I'll be looking you up when it's time.
One of these days Schick will come out with an EVEN BETTER razor--9 BLADES to give you a SUPER DUPER CLEAN shave. Are props like that too? Will we see 5 blades soon?

Like Jimbo pointed out, there are some props out there with more blades. As I understand it, the fewer the blades, the more efficient a prop is. Thats why 3-blades generally have a higher top speed than comparable 4-blades. The new Acme's have a ton of surface area, so they dont give up much (if anything) out of the hole compared to 4-blades. I think I read somewhere on this site that race boats use small 2-blade props and tugboats use large 4 or 5-blades. The analogy seems to make sense. ------------- |

I bought mine from New England Correct Craft. I don't know where the rest of the guys got theirs.
I noticed with the 540 prop, it puts pressure on the steering wheel when turning right. You can actually hear it digging in. I feel like my boat is going to suck other boats in when I pa$$ them.

$300 is the cheapest I've seen the 540. The best I saw was $349.00, shipping not included. You got a fantastic deal, Heath. I don't think any walk-in marine store sells the 540.

| when you compare the acme to the oj you must compare the oj xmp version. this is the cnc version. i tried the acme 3 blade #470. my oj xmp 4 blade is a better prop. the hole shot is about equal but the midrange performance of the oj is 300 rpms less at wakeboarding speeds around 20mph. my top end is also 2mph faster with the oj. i use about 3.3 gallons of fuel/hr with the oj. and about 4.1 gallons with the acme. i sent the acme back and bought another oj xmp 4 blade 13x15.5. it also runs smoother. |

after terminating several 4 blade OJ's i had the bright idea to replace it with a S/S wheel of some type. called and talked to several boat and trans. guys......... bottom line props are cheap; planataries and inards of a Velvet Drive are not. use the prop as the weak link of the chain,replace the nibral prop and you ski that day, break the tranny or shaft and you don't............ boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Can someone please tell me if my 79 Ski Tique has enough clearance to run a Acme 540? I have asked a lot and no straight answer yet. Boat dr. do you know? The stock Federal on it is smaller than what came on the Nautiques of the same year.

79' Acme once told me that a 540 would not work on my 78' Tigue with a 305, but I believe they recommended a "514" ??? I never went for it because I bought a SN with a 540 on it....

Anyone using the Acme #470 three blade on a SN. When I spoke with them it seemed like a good choice for my 95 snob. Still trying to decide three or four blade??
ernest pushing for one for xmas. |
Posted By: TRBenj
Date Posted: October-24-2006 at 9:52am
Yup, Ive got one on my boat. Its a better prop than the Acme 422 (4 blade), Ive tried them both on mine and my father's boats. If youre currently running an 4-blade OJ legend, you'll notice a huge improvement with the 470. You'll turn 200 RPM higher on the top end, and the boat will be quicker and more responsive at all speeds. ------------- |

boat dr, I just reread your reply and went out and looked at the boat and I think I understand what you mentioned.
I measured from the center of the shaft at the rear edge of the prop, to the hull is 7". From the end of the shaft to the rudder is 4". Is this to tight? ------------- Work to live, not live to work. |

| I have an 88 2001 with a dinged up prop. Prop is a 3 blade, 13x13 ni-bral cup with a 1" tapered shaft. I think this is the original prop. Motor in boat is 351. Boat is being used for both skiing and wakeboarding. Question is, should I fix this prop or replace it (and if so with what?) I'm up in BC Canada so have lots of time to consider options! |

Do you have a spare prop? If not, its worth considering a new one and having the old repaired to keep as a backup. That way youre not out of commision for a few weeks during the summer if you damage your prop again.
Do you weight your boat? Do you do much barefooting? Both the Acme 540 and 542 are highly regarded and will outperform that original prop. The 542 will have the better holeshot, while the 540 will give you a little more speed. ------------- |

Steve,
I speak from recent experience....you won't be disappointed with an Acme prop if you are accustomed to the original. I had an OJ 4 blade and went to the 540 and wondered why I didn't do it sooner. ------------- Heath |

Does any one think I would be making a mistake by going with the 542 over the 540. My Tique has a 302 and I want more hole shot. ------------- Work to live, not live to work. |
Posted By: TRBenj
Date Posted: November-27-2006 at 8:59am
|
It depends. What are you running for top speed/RPM now? What are you planning on doing with the boat?
If you dont plan on adding weight, then I think you'll be impressed with the holeshot of the 540. The 542 will probably be a little slower on the top end- which may be important if you barefoot. ------------- |

My suggestion is the 542 for 302's or smaller and the 540 for the 351's. I run a 542 behind a 289 and get 30 MPH at 3000 RPM's and 40 MPH at 4000 RPM's. Great hole shot and also cured porpoising. I was actually hoping for a few hundred more RPM at each MPH, but I still like the prop.
Pulling a 200 LB plus slalom skier is easy and the boat keeps speed even when the big boy is rounding a buoy. ------------- 64 Skier 66" HO VTX and 67" HO Triumph http://www.correctcraftfan.com/diaries/details.asp?ID=1071&sort=&pagenum=3&yrstart=1971&yrend=1975 - 71CC |
