Thanks for the info guys, I asked him for mph #'s from 4k to 6k in 500rpm increments, it does have gps speedo but he wasn't watching it, it is a trs boat so I don't want to put to much stress on them, boats been sitting for 5 years, I fixed the engine problems a few weeks ago he's just glad to be back on the water.

With TRS and 575-600 HP personally I would stick with 3 blades if he beats it at all, leave that couple % of slip trust me... I bet a worked 25 mirage will perform great and help keep drives alive, that power level is about all them tiny lower gears will take and stay together, 4 blades or more then 600 HP create time bombs.
