PROPELLERS AND PROPELLER SHAFTS
Each marine transmission output flange is coupled to a 2-1/2 inch Corrosion Resistant Steel (CRES) propeller shaft. The
propeller shafts transmit the rotating energy from the marine transmissions to the propellers.
The propellers exit the hull through stern tubes located between frames 37 and 39, port and starboard. Each stern tube is
fitted with a stuffing box that provides a watertight seal for the propeller shaft as it passes through the hull. Heavy duty hose
and hose clamps secure the stuffing boxes to the stern tubes.

PROPELLERS AND PROPELLER SHAFTS (TYPICAL)
The propeller shafts are supported by two bearings. The forward section of the propeller shaft is supported by a stern tube
bearing located in the stern tube. The aft section of the propeller shaft is supported by a cutless bearing located in a V-strut.
The propellers transform the rotating energy of the propulsion engine and marine transmission into forward or reverse thrust
to propel the vessel. The propellers are secured to the trailing ends of the propeller shafts with jam nuts, plain nuts, and
cotter pins. The propellers have tapered, keyed bores that are secured to the tapered, keyed propeller shaft ends to prevent
the propellers from rotating on the shafts.
