Packing Box, Hose & Oval Base Shaft Log

A packing box, or stuffing box, is a device that seals around the propeller shaft where it exits the vessel via a shaft log, preventing seawater from entering the boat.
The shaft log, which is fiberglassed and/or drilled and bolted to the hull, is the actual opening through which the propeller shaft exits the vessel.
The hose connection between the packing box and the shaft log provides enough flexibility to allow for small shaft alignment discrepancies.
