I have a 94 prostar 190 with a 13 x 13 OJ 3 blade on it,,, my buddy has the same boat with a four blade and says it lessened the bump at 22 off.. anyone have any knowledge of this? I used to have a 2001 190 and I replaced the four blade with a machined 13 x 11.5 and it was much smoother and a better wake at 22..... Thanks

FWIW, when I switched from the standard 3 blade to a standard 4 blade (not CNC or anything special) on my '89, I did notice a smaller bump at 22 and a better hole shot. Not much improvement, but some. I'd guess going to a CNC prop would make a bigger difference.

What are the dimensions of your 4 blade? Do you have a powerslot tranny?
Thanks!
