Close the thm-hull sea cock, Remove the sea water intake hose from the sea cock, Place the end
of
this
hose Into a 5-gallon bucket of clean fresh water- Belore starting
the
engine, check the zinc anode found
in
the primary heat exchanger on the engine and clean
or
replace it as required, Clean the sea strainer, if one
is
installed in the inside
of
the hull.
Start
the
engine and allow the sea water
pump
to
draw fresh water through the system, When the bucket
is empty,
stop
the engine and refill the bucket with an antifreeze solution slightly stronger than needed for
winter
freeze protection in
your
area,
Start
the
engine and allow all
01
this mixture 10 be drawn through the sea water system, Once the bucket is
empty, stop
the
engine, This antifreeze mixture should protect the sea water circuit from freezing during the
winter
lay-up, as well as providing corrosion protection,
Remove the impeller
from
your
sea water
pump
(some antifreeze mixture will
accompany
it,
so catch it in a
bucket), Examine the
impeller. Acquire a replacement, if needed, and a cover
gasket
Do
not replace the
impeller (into the pump)
until recommissioning, but replace the cover and
gasket
Intake
Manifold
and
Through-Hull
Exhaust
Place a clean cloth, lightly soaked in lubricating oil, around the air arrester. Be sure
to
remove this cloth
before recommissioning, Make a note
to
remove the cloth prior
to
start-up, The through-hull exhaust part
can be blocked in the same manner.
Starter
Motor
Lubrication and cleaning of the starter drive pinion is advisabie, if access
to
the starter permits its easy
removal. Ensure that the battery connections are shut off before attempting
to
remove the starter. Take care
in properly replacing any electrical connections removed
Irom
the starter.
Cylinder
Lubrication
Fogging the engine should be done as the last
of
the antifreeze mixture is drawn into the sea water
circuit
Remove the air intake screen (the air filter) and spray Marvel Mystery Oil
or
another commercially available
fogging
oil into the carburetor while the engine is running, Spray enough oii
to
stall the engine, This will
coat the
walls
01
the cylinders, pistons, and valve surfaces with this protective oil. Remove the spark plugs
and spray a
small amount of this oil into each spark plug hole and turn the engine over
two
or
three com-
plete revolutions
by
hand, Reinstall, but
do
nol
tighten, the spark plugs, as these will need
to
be cleaned
and gapped prior
to
recommissioning, Close off the carburetor's air lilter with an oily rag,
Spares
Lay-up time provides a good opportunity
to
inspect the equipment 10 see if external ilerns such as drive belts
or
coolanl hoses need replacement Check
your
besic spares kit and order items not
on
hand,
or
replace
those items
used during the lay-up, such as lilters and zinc anodes,
