I have a 91 maristar 454 that has a 541 13 X 12V prop on it now. At approx. 7,000 feet elevation lakes I hit 4300 rpm WOT. from what I understand I should be at 5k WOT. I don't care too much for higher speeds, I am more concerned about bottom end. The prop I have now pulls really good, but is there a better option.

I'm running my boat near that elevation and Eric at OJ just sent me out a different pitch to try and see if I like. I'd definitly recommend him after he spent quality time with me on a phone call discussing altitude vs. pitch theory's.
