Have a 2022 CX 21 with a 300R, started with a 26 Fury, then 25, and then a 24, reached 6200 barely with the 24, need to be in the 6400 range for optimum performance, had the hotfoot checked twice to make sure we were getting WOT, it all checked out so my dealer decided to install wedges, bingo, hit 6400 rpms and 80 mph, he said he ran out of lake, felt like he could have hit 81-82. That is with the 25 Fury, I have a 25 Tempest on the way, thinking it will be faster, plan on having it worked after i run it, heard Mark Croxton has retired, did he sell his business to someone who can work the prop, if not does anyone know of someone who is as good with Tempest props ?
