OEM Prop for 01 21V

[wakehero5000]

Hey,

Can anyone tell me what the OEM prop would have been for my 2001 21v?

Thanks!

Matt

Why? Dollars to donuts it was an old OJ. Props have come a long way since then. If you need a new one, call Acme.

There's a four blade on right now. Just had the boat repowered, but it feels weak out of the hole and max rpms are only reaching 3400.

I bought the boat in October, just trying to determine whether the current prop is the one tige put on or was replaced by previous owner.

Probably doesn't matter like you said. I will be using the boat primarily for wakeboarding and surfing with up to 6 adults and 800lb sack.

From what I've read, a 3 blade(acme 653) seems to be the preferable prop for my application. We ride at sea level.

Probably a cutter stainless. They put those on and they were pitched for ski boats. Great for skiing, lousy for wakeboarding and useless for surfing. Ditch it and call Acme. Best move you could make. You will think you have a new engine.

Ahh, yup. Call Acme. They will ask you all the right questions and determine what prop you need based on your needs, your boat and your location. I run a 653 but I run the boat anywhere from 4500'-6500'. Don't assume its perfect for your boat. Just call. It's easy.

From what your describing, it sounds like you have the stock OJ on there or as laser said the stainless(I forgot about that one, thanks laser). Keep it for a spare and put a 21st century prop on there. It will make a world of difference.

Congrats on the boat. Let's see some pics.

Thanks so much Nicky and Laser, I'm gonna call ACME right now. I'll let ya know what they say. I'll get some pics up soon.

That's what this forum is for. Someday your experience may help somebody else out so don't be shy, post up what you find.

Thanks so much Nicky and Laser, I'm gonna call ACME right now.

You'll love calling Acme. They're awesome. I learned a lot about props, boats, and engines just talking to them. Answer their questions, do exactly what they say, and you'll be thrilled.

Our 2000 21V came with an OJ 14”-18, 1 1/”8, LH, 4 blade.
In 2003 Tige switched to an Acme #537 13.5”-16, 1 1/8”, LH, 4 blade.
After switching to the 537 ours had a lot more pickup out of the hole.
We usually wakeboard and tube with 8-10 people.
For surfing you might want to go one more level.
Call Acme, you'll need the engine info and V-drive ratio (probably 1.46:1, blue or 1:1, black).

You guys are all awesome! Thanks so much for all the feedback. I'm loving being on this forum already.

So I called ACME and talked to a helpful guy named Bill. I have the 1:1 ratio drive, so Bill recommended the 525 or 653. He said I should expect an extra 100 rpms and a little more power with the 653. So I am currently shopping for one of these props. The plan is to get either prop ASAP and then the other model closer to summer and see which one we prefer.

We will be using this boat commercially, offering wakeboarding, wakesurfing lessons as well as kneeboarding and tubing (unfortunately a majority of people just wanna tube but its there $ so whatever blows your hair back).

We are in Hilton Head Island, SC. If anybody on the forum plans on coming to HHI, let me know. We will be happy to take you for a pull.
