I'm sure this has been discussed before, but for a prop upgrade should I go with a 3 or 4?? I have the factory 3 on their now, and it just looks tiny! What brand works well, doesn't loose much top end, and pulls well out of the hole. Thanks for the opinions.

ACME and OJ are the two major manufacturing companies for props that are used on MC boats. There was a prop test done on here awhile ago, and East TX skier can email you the results.

What are you going to use the boat for? That will narrow done the prop you'll want.

really depends on the boat and the use...

Its a '93 Prostar 190, mainly going to be used for slalom. Not much in the course, more free ski. I like having a nice hole shot, which I'm not sure how much a prop will change this boat, but maybe you guys will. Thanks!

Sounds like an Acme would do you nicely. Is the boat powerslot transmission?

I have been reading about that and I want to know now. How do I find out? That would be neat if it was, but I have no idea how to even find out!

You can look at the transmission on the boat. It should list a model on there.

I'm not sure if the HIN# tells you that. You can ask Sporty to decipher your HIN#.

Here is the section of the FAQ thread that deals w/ hull ID--

The powerslot is the 1.5:1 transmission.

What size prop is it? If it's 13x13x1, you have a 1:1. If your drive shaft is 1.25", you've got a powerslot.

The prop comparison I did will give you a pretty good run down of everything.

And it was very well done as I recall.

Thanks. The link in the FAQ was updated. The download is in MS Word Format.

I have a 1993 PS190 with a 285 hp 351 ford 1 to 1. I ran stock OJ 13x13 3 blade, 13x13 OJ 4 blade and an ACME 13x13 3 blade CNC. The 541 smokes them both in feel, wake, acceleration and smoothness. No offense to OJ as I did not give there CNC a go. Over the standard OJ 541 wins hands down. 4 Blade torque and acceleration with 3 blade speed. OJ or ACME go with the 3 blade CNC. The three blade actually has as much surface area as the standard four! Good luck and you will feel a big difference over stock. IMO! :D QUOTE=aerojt]I'm sure this has been discussed before, but for a prop upgrade should I go with a 3 or 4?? I have the factory 3 on their now, and it just looks tiny!

I don't believe the OJ XMP has the same surface area in its 3 blade as in its four blade. Were I to buy an XMP, I'd probably go with the four blade or drop pitch to 11.5 in the 3 blade.

As far as smoothness/vibration free performance goes, I couldn't tell the difference between acme and oj xmp.
