Either one just may satisfy your needs but you'll never know which one is better without running them both...

Basically what everyone here has said yes. But, just like the prop shop he can't guarantee performance. I would spin buying both props if they aren't special order and returning the one that doesn't perform as well.

Sorry I did not notice the posts a couple above. I will ask them again If that is something they would do. It would be nerve wracking to have 800 dollars wrapped up in props that are just waiting to be dinged just once. But thats the risk you have to take I guess.

Not me. You! lol Or buy one and if you like it be done with this. Do you need the absolute best prop or one that is good enough? |

Yea. You're basically spending 400 bucks for 1 mph ha. I wouldn't probably do that but if you actually need that 1 mph make it happen. I'm sure we've all blown money on way stupider things.

If it was just 1 mph WOT it might not make sense, but seems like the hope is that while footing it might be one, might be two mph and the difference in being able to one-foot.
Landis, another option is to drop 30 lbs.! |

You're skiing at 70' with an extended pylon right? If not you should be.

Ha, I used to think I needed to go way faster to one foot than I did. Now it's easy at most speeds. Then again I only weigh 135 lbs.

He doesn't own an acme yet so it's not $400 wasted by any stretch.
I think there is a high probability that the 1609 with the factory .120 cup is going to put you in the same 4500 ballpark that the 543 would. I do not like cup doing the job of pitch and would choose the 543 between those 2 (additional cup makes the prop less efficient). The 913 will put you closer to 4800. Unloaded, both are gonna turn very close speeds, but I'd be shooting for the 4600-4800rpm range, and I generally prefer to aim towards the high end. That produces the best all around performance in my experience. That and the fact that you're gonna be putting a load on it (which will drag rpm down incrementally) tips the scale in favor of the 913, IMHO. Hw is right. You'll never know which runs better unless you try both. I've seen variation between 2 new factory props (same model) so this isn't quite an exact science... At this point you've beaten the subject to death and everyone has had the chance to weigh in. Time to make a decision and run it. |

Sorry, mixed up the 1609 and 1229.
.020 difference between 543 and 1609 is a step in the right direction but it's a very, very small step. Still gonna leave you short of 4600 in all likelihood. Advice still stands. |

We'd all like to see it at 4800. I'm just not sure physics is going to allow...

Yeah I dont know. I dont like buying things without having a good feeling about it and this one is just got me stressed out. Maybe next year I could sell and get an outboard. I have about 10 buddies that have boats that are great and better than mine for salom (3- 97-2001 SN's) but as of now my boat goes the fastest so we dont have a good barefoot boat in the arsenal. If I bought an outboard I could never seriously slalom or trick ski.
I do think the SN 176 with the efi motor in it would be the ticket for the best do it all boat. |

Get a carb like Eddie said earlier.
280hp (plus??) in a 176 would be nice boat for you. What engines do those Nautiques have? |

Where is Frankenotter, he keeps talking about upgrading to a late 90's Ski, Here you go Boozer, sell that 176 (no EFI) and move on up AND we don't want to hear anymore about your garage being too small!!! |

Probably 310hp GT-40s..... and you think you've got room for improvement with your 260hp Chevy.

i dont understand that last part. http://correctcraftfan.com/forsale/details.asp?ID=7971&sort=&pagenum=1 This would be really nice. I would just change the decals on the side to say ski nautique 176 so ppl dont think I wakeboard. |

Most 176's came with carb 260 hp but a few did find GT40's in them. I wouldn't completely rule out an outboard for slalom.

Mark (LLS) sold his inboard and bought one of these. He could never get the 1 or 2 extra MPH out of his inboard for footing and we're nowhere near the altitude!!

2 words: tsc Python
The gt40 tsc's can't muster any better than 41? That doesn't seem right. Those are 46mph boats closer to sea level. |

That is what I need but what I really need is a bf sanger with a 250 on it. And his has a 4blade on it. I told him if I sold my boat I would buy him a 3 blade and I would just foot off of it. |

Shoot here I go asking more questions a guy wants to trade me a OJ 13x11 .9 cup for my 541. Is that a good prop? or is Oj not as good? It is CNC.

Oj doesn't offer any props in their xmp line in RH except for the few 1.23 props... So little experience exists on the 1:1 sized xmp's here. That said, ETS did a compare on the MC site between 13x12 CNC acme/Oj and the results were very close.
Based on the dimensions, I'd be inclined to make the trade to the 13x11. |
