Im currently looking for a 3 blade powertech prop or possible a 4 blade cupped prop. Anyone has one I can try before I buy a new one. Just need 30 mins of your time to try it out. Right now my yamaha 25hp 2 stroke has a stock prop 11 7/8" 3 blade and it blew out a little while jump on plane. Im looking for a PT 3 Blade SRA 10 to 12 pitch. Let me know and thanks!
