### One Piece Propeller Shaft Phasing Correction

An out of phase single-piece propeller shaft is very unusual. If the phasing inspection procedure revealed that prop shaft is not phased correctly, the welded yokes are in the wrong position, or the shaft is damaged due to twisting and the propeller shaft requires replacement to restore proper cancellation of the U-joints.

### Multiple-Piece Propeller Shaft Phasing Correction

1. If the phasing inspection procedure revealed that a prop shaft is not phased correctly to the mating slip yoke, the end yoke is welded on in the wrong position, the slip yoke is mis-aligned to the stub shaft, or the shaft is damaged due to twisting.
2. If the shaft if visibly damaged, it requires replacement.
3. If the shaft exhibits no visual physical defects or damage, perform the following:

3.1. | Remove the slip yoke from the stub shaft to determine if it is possible to reinstall the slip yoke in a different position on the stub shaft.

3.2. | If the stub shaft is keyed to ensure proper alignment of the stub shaft and the slip yoke, then the propeller shafts require replacement to restore proper cancellation of the U-joints.

3.3. | If the stub shaft is not keyed, attempt to re-align the front shaft and slip yoke to each other. Repeat the inspection procedure to confirm the results.

3.4. | If proper phasing cannot be obtained, the propeller shaft requires replacement to restore proper cancellation of the U-joints.
