Is anyone running a tempest prop with the 225efi on a gambler? I need to know what pitch to try on. Guessing a 26P. I have been running a 27 Trophy Plus, one stock (79.2mph) and one worked by Mark Croxton (running 79mph but I have only run it once). I have sent the one prop back to Mark once already and it looks like it still needs some more fine tuning. Great out of the hole but slower on top end than the stock one. Just want to know what pitch Tempest to try on it? Thanks Charley
