I have a Rev 4 21" on my Baja 252 Islander, the prop is incredible. INSTANTLY up on plane, holds extremely well even in the tightest turn...I couldn't be happier.

Hi
I have a 1987 formula 242. ls mag 452 with an aftermarket intake manifold and crane cam that was installed by one of the previous owners.
I trying to get on plane somewhat faster than I do now. Currently turning a Mirage 14x21 stainless 3 blade. I would like to try a stainless four blade. I have read and been told that when changing from three to four blade props you usually drop down one pitch. I did try a turning point 4 blade 21 with no notice left increase in performance.
Any suggestions/recommendations would be greatly appreciated. I know the 242 ls is not a speed demon, but I would sacrifice a couple of mph for better low end performance.
Thank you
Tony S
