The shaft comes out real easy if you first remove the cutlass bearing!

Most major marine areas have at least one.  You should consider Aquamet or Aqualoy 22 material, look at descriptions. Make sure you get the correct length, taper and thread and keyway. Again, I've found the best way is to take the old shaft, coupler and new prop to a competent prop shop and have them do the entire fabrication job.  You will also have to determine how best to remove and replace the shaft because it is difficult sometimes to get the shaft the past the rudder without dropping the rudder.
