Propeller Shaft (016-025)
General Information
Improper alignment of the propeller shaft can result in
many problems. Vibration is usually the first indicator.
Failure of the shaft seal or stuffing box can also occur. If
damaged shaft seals, stuffing box, strut, cutlass bearing,
or propeller are found, refer to an authorized OEM repair
location.
Preparatory Steps
Shaft alignment is checked when isolators are replaced,
adjusted, or any time excessive vibration has been
noticed. Also, any time the vessel has been taken out of
the water and stored or blocked minor changes can take
place in the shape of the hull. The shaft is checked and
realigned as necessary after the vessel has been placed
back in the water.
Out of Water
Inspect the propeller shaft for debris and burrs. Clean the
propeller shaft.
Check that the shaft is centered in the opening of the
stuffing box flange. The specifications will vary by
manufacturer. If any problems are noted, refer to an
authorized OEM service location.
