Just like you, my Sabre FTD w/ 175 Pro XS came with a 25 Tempest. It was not the right prop for my load… I run a fairly heavy load. After trying a 24 Tempest, 25 Tempest, 24 Trophy, 24 Trophy Plus, 25 Trophy Plus, 24 Fury and 25 Fury….I finally settled on a 24 Fury. For my load, and living in Texas, this prop has the best 4 season all around performance. Great hole shot, Max RPMS close to 5800 – 5900, and top end is 67 to 68 with a 2 person, full load…
