Prop question/suggestion/problem

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.

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?

Its amazing what you will do to try to learn 1 foots.

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

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 eat this stuff up ha. No worries. I would like to see the Chevy at 4700-4800. Chevys like rpm.

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.

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.

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!!

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.

Anyone else also still fuzzy on which brand, year, model boat and engine marinizarion we are speaking about?
