25 tempest w/ OMC hub – the standard answer for Pantera/200! Or, the prop that is on the boat will work if it provides the performance you are looking for. From what I have read on the P2/200, it should run right at 70mph WOT and around 5800-5900rpms. If you are looking for something in particular out of this boat ( top speed, best handling, quick hole shot) let us know cause it will be easier to determine the correct prop.
