Slowly drew the prop onto the lugs by tightening the bolts around the hub in sequence. When the bolts had pulled the prop to the bottom of the lugs, I check the torque specs. Max torque is 15 ft-lbs (20 N-M) but 10 ft-lbs (120 in-lbs or 14 N-M) was recommended in order to ensure the bolts were not over-tight.
