I've had that happen 3 times. Just pull the pin, remove the fin, get a large box end wrench. Slide the box end down to the area of the bend hold the drive with one hand and when the wrench is in the correct area just above the bent use the length of the wrench to bend it straight again. Do not need to always remove the mast. In an emergency you can provably straighten it enough after removing the pin and fin and just using your hands and brace the mirage drive against the ground. No need to replace the mast unless it's cracked or it's been bent in the same place a handful of times.
