Www.Nettleprops.com out of Texas has the best prices I have found so far. 1433 for $485 new. I recently got 1433 to use as primary and stock as spare. Bought the acme weekend saver kit from wakemakers. My stock was on the boat since 05 and I eventually had to spray some aero kroil (or wd40) and a heat gun to get it to pop off. The 1433 for me was the recommended for wakeboard / wakesurf. For your boat that would be the 1939. The 1433 would be high elevation/ heavily weighted.
