Sea Water
Circuit
Close the through-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. Before 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 of this mixture to 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. See the "Cylinder Lubrica-
tion" section
below.
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 port
can be
blocked in the same manner.
Starter
Motor
Lubrication and cleaning
of
the starter drive pinion is advisable, if access
to
the starter permits its easy
removal. Make sure the battery connections are shut off before attempting
to
remove the starter. Take care
in
properly replacing any electrical connections removed from 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 oil
to
stall the engine. This will
coat the
walls
of
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
not tighten, the spark plugs, as these will need
to
be
cleaned
and gapped prior
to
recommissioning. Close off the carburetor's air filter with an oily rag.
Spares
Lay-up time provides a good opportunity to inspect the equipment
to
see if external items such as drive belts
or
coolant hoses need replacement. Check your basic spares kit and order
ITems
not on hand,
or
replace
those
ITems
used during the lay-up, such as filters and zinc anodes. Refer
to
the "SPARE PARTS" section

this manual, page
