Need help from Ht or any of the guys. I have owned my Ranger 06 Z-20 w/225 hpdi since it was new, I know they are not the fastest!! My best was 71 after prop mod by Mark Croxton..Usually with two 1/2 tanks and tackle between 67-69.What could add more speed (top end) at a reasonable price?? Anyone have this set-up and done any modifications???
