To prevent personal injury, keep away from the
propulsion machinery  during its  operation or
whenever the boat is in motion.  Movement of
water past a propeller can cause the propeller,
propeller shaft, and other propulsion machinery
to rotate  even if  that equipment  is not  being
operated intentionally.

To prevent water from entering into the boat, al-
ways be  sure the lock nuts  are tightened se-
curely to prevent the packing nuts from loosen-
ing.  DO NOT attempt to  tighten the lock nuts
without the proper equipment to hold the pac-
king nut stationary.

rence, proceed at low speed to the nearest ser-
vice facility and have an immediate inspection
made of the prop shafts and struts before further
use of the craft. Keep all life saving devices at
hand while driving to a  dock area.  If the boat
cannot be immediately removed from the water,
thoroughly inspect the  bilge area for leaks  so
that the boat does not sink while moored.
B.   Strut
The strut secures the lower end  of the propeller shaft.
Seasonal inspection of each strut should be made to in-
sure no damage has incurred and the strut bearing is not
worn excessively.
When the boat is removed from the water for winteriza-
tion or general maintenance,  apply a light water proof
the shaft where it penetrates the strut bearing.  This will
keep the strut bearing from drying out. Replace the strut
bearing should it become worn or cracked.
A.   Shaft Log
The shaft log allows  the propeller shaft to extend  and
rotate through the hull  with only limited water leakage
occurring. Minor dripping may occur and is not abnormal
during operation. See Figure E1 & E2.
