what would be a good CNC prop for a powerslot 91? I know I am limited to a 4 blade. is there one that is comparable to a Acme 541?? I know that thats the king of three blades?

thanks

I replaced the old 3 blade on my 91 Prostar (w/Powerslot) with an ACME 381. Not that I needed it but it did improve my hole shot. The main thing I noticed was that the skier's pull is less noticeable and requires less throttle compensation. I also lost appr. 2mph on the topend.

Suggested retail is over $500? - yikes. The Acme 847 CNC four-blade (splined) I just bought was $400, both direct from Acme and from my local prop guy. I wonder why that one would be so much more expensive?

Even so, $229 was a fantastic deal...congratulations.

Doo,

I did an ACME 4 blade CNC. its a #275. I have a 91 With a powerslot too. Bill recommended this prop and its awesome. The holeshot is amazing on it. Much smoother than my old OJ prop. no vibration, holds speed better, especially in corners. Call Bill Weeks at ACME and tell him what you got, and what your looking for, and he will hook you up with a great prop. :D
