Hauled today at 11:15 and the shop worked till 2:30 trying to remove my props. They would not budge. First they used a puller with two threaded rods into the hub and a torch. Destroyed the puller. Next was a chain puller and torch. The hub fittings failed on the chain puller from all the torque. We are trying to avoid driving my shafts into the gears with a sledge. Any tips? Fortunately these props perform fine and there is no emergency to get them off so I went back overboard. These are 5 blades with two threaded holes on 2 1/2 shafts.
