Wrap the packing material (11) around the propeller shaft (10) to determine the proper length for the new packing material
sections. Cut the ends square and allow them to overlap approximately 1/16 inch (0.16 mm) to permit a snug fit in the
stuffing box.

Slide the packing material sections into the aft section of the stuffing box (5). Stagger the end gaps of the packing
material section to prevent excessive leakage.
