Prop Help!

I am currently running the stock three blade prop on my '96 Prostar 190 LT-1 w/ a PowerSlot Transmission. I would like to move to a 4-blade CNC and keep my old prop as a spare. Has anyone done this? Can anyone shed some light on the subject? I do not want to spend $400 on a prop that does not work! Also, what brand does everyone run? Any suggestions would be great!

I went with a 3 blade acme 543, but I wakeboard.
If you ski, I think the 541 is closer to what you want.
The acme was a great improvement over the original Prop.
But the one I have is not four blade. Maybe someone else can give some input.

If you haven't, do a search and read the past history. There are new CNC props from both OJ and ACME that many on here have bought and absolutely love. I've bought, but not changed yet. Doug did a side by side performance comarison of each.

No need to go four blade. Stick with the CNC 3 blade. I am running an Acme #541 on my '97 190 TBI 1:1 and love it. My ski partner has a '97 205 LT1 1:1 and switched to the OJ XMP 13x12 (same size as the Acme) and is equaly as happy. Either prop is a great choice. Better hole shot, no loss in top end and much better holding power through the course not to mention vibration free and quiet.

Acme 541

I put the 541 (13x12) on my 88 TriStar and the difference was amazing. Great hole shot, holds well and no loss of top end. It took out almost all of the boats vibration.

Also - I saw the clamp below at Lowes for about $10. I figured with some heat from a torch it might work - at least worth a try before I shelled out $70 for a prop puller. A little heat, a couple of light taps, and the prop (original - probably never removed) came right off. Just remember to remove the rubber ends if you are using a torch - they burn.

I'm running the Acme #541 and continue to love it two years after the purchase. Stick with the 3 blade IMO. That said, my father is running a 4 blade XMP and likes it fine. In my tests, the 3 blade OJ XMP performed very well.

www.wakesiderides.com may have picked up my prop test as a host, but I don't remember whether they did or not. If they don't have it, pm me your email address, and I'll email the test to you.

4-Blade?

So everyone thinks a three blade is better than a four blade? I slalom ski, so I am just looking for a better hole shot and top speed is not an issue (36 mph is all i need!!). That sounds great though, I would love to loose some vibration in the boat. Thanks Guys!

Go Horns!

At least in the case of the Acme, the surface area of the 3 blade is the same as the four blade. So, according to them, hole shot is the same in either prop without having to sacrifice top end.

In comparing the blades of the Acme and OJ XMP in my test, the surface area on the same sized prop was larger with the acme.

In my extremely unscientific test, I changed my (likely original) 3 blade for a new 4 blade, when my sister accidentally hit a rock. I have no idea what manuf/material the 4 blade is. This was about 8 years ago. Same dia. and pitch though. I put the reconditioned 3 blade back on a few times (I keep it as a spare, it is perfectly balanced), and have noticed the following: The 4 is a tiny little bit smoother, but maybe that's in my head! The 4 seems to give me a smaller/softer rooster tail. The 4 seems to get up to speed quicker, and better hole shot. The 4 seems to steer & track better. I think the 3 may give me 1/2 mph more top speed, at best. Some day, I need to swap props in between sets on the same day, just so I can tell better.
Probably not much help, but my anyways.
