I have a 98 202 Dcx with a 200 mercury efi 2.5L, I can only get it up to 55. I do have a 4 blade prop right now but I tried a 25 pitch 3 blade and the holeshot was terrible and I got it up to almost 60. Is that about average for this boat or is there something I can do to get it faster? Any suggestions would be appreciated! Thanks!
