This has been hashed over many-a-time......do a search on this site

I did a search on "3 blade 4 blade" and came up with a ton of threads including this one.....

You can PM east TX skier for his "prop test" results as well.

There is an updated link to download the test as a word file in the faq.

With the acme props, the two props supposedly have same surface area. So performance is supposed to be about the same. With other props, more blades means more surface area.

From what I have read in various places a 4 blade can get you maybe some more holeshot and better holding power at lower speeds (wakeboarding) but you sacrifice your top end, and in the case of some boats like my 86' MC was, you mess up the wakeless, frothy, propwash. 3 blades you gain/lose just the opposite.

Personally, I am all about the Acme 541, I'll own one on whatever boats I have in the future. I am sold!

I think less and less with new CNC machining ability.

On a ski/wakeboard boat, 4 Blade for me, and will continue that theory until someone proves to me 5 blades are better than 4......:D

The new cnc'd 3 blades are typically recommended over the 4 bladers on smaller ski boats from what i've seen.

From my comparisons, if you go with OJ's XMP (CNC'd) prop, 4 blade is the way to go (or go with less pitch (like 11.5). My father-in-law is currently running one and likes it very much. If you go Acme, the 3 blade props have larger blade surface area than the 3 blade OJ and thus, from my experience, you can get that nice hole shot from a 3 blade prop and keep your top end.
