shaft.
two grooves
running the full length
of the
hub.
Hold the shaft
from turning,
and then
rotate
the propeller
1/4 turn to position the
grooves over the shear pin holes.
The pro-
peller
can then
be pulled
straight
off
the
shaft.
After
the propeller
has been remov-
ed, file the shear pin holes on both sides of
the shaft to remove the burrs.
If
the
propeller
is the

the
shear
pin installed

DRAINING
LOWER
UNIT
Position
a suitable
container
under
the
lower unit, and then remove the FILL screw
and the VENT screw.
CRITICAL
WORD
The Phillips screw securing the shift fork
in place
is
located
very dose
to the
vent
screw.
If
the
wrong
screw
is
removed,
BAD NEWS, VERY BAD NEWS.
The lower
unit will have to be disassembled
in order to
return the shift fork to its proper location.
Allow the
gear
lubricant
to drain
into
the
container.
As
the
lubricant
drains,
catch some with your fingers, from time-to-
time,
and rub it between
your thumb
and
finger
to determine
if any metal
particles
are
present.
If metal
is
detected
in the
lubricant,
the unit must be completely
dis-
assembled,
inspected,
and
the
damaged
parts replaced.
Check
the
color
of the lubricant
as it
drains.
A whitish or creamy
color indicates
the
presence
of
water
in
the
lubricant.
Check
the
drain
pan
for
signs
of
water
separation
from the lubricant.
The presence
of any water
in the
gear
lubricant
is BAD
NEWS.
The unit must be completely
disas-
sembled,
inspected,
the
cause
of the prob-
lem determined,
and then corrected.
Filling
instructions
are
outlined
at
the
end of each lower unit section.

NOT have to be removed in order to accom-
plish the work.
