LAY-UP
AND
RECOMMISSIONING
General
Many owners rely
on
their boatyards to prepare their craft,
including engines and generators, for lay-up during the off-
season
or
for
long
periods
of
inactivity. Others prefer to
accomplish lay-up preparation themselves.
The
procedures which follow will allow you to perfonn your
own lay-up and recommissioning, or to use as a check list
if
others do the procedures.
These procedures should afford your engine protection dur-
ing a lay-up and also help familiarize you with the mainte-
nance needs
of
your
engine.
If
you
have any questions regarding lay-up procedures, call
your local servicing dealer;
he
will be more than willing to
provide assistance.
Fresh
Water
Cooling
System
A 50-50 solution
of
antifreeze and distilled water
is
recom-
mended for use
in
the fresh water cooling system at all times.
This solution
may
require a higher concentration
of
antifreeze,
depending
on the area's winter climate. Check the
solution to make sure the antifreeze protection
is
adequate.
Should more antifreeze be needed, drain an appropriate
amount from the engine block and add a more concentrated
mixture.
Operate the engine to ensure a complete circulation
and mixture
of
the antifreeze concentration throughout the
cooling system. Now recheck the antifreeze solution's
strength.
Lubrication
System
With the engine warm, drain all the lubricating oil from the
oil sump.
Remove
and replace the oil filter. (Place some
paper towels and a plastic bag around the filter
to
catch the
oil during its removal.)
When installing the new oil filter, be sure to apply a small
amount
of
oil
on
the rubber sealing gasket at the base
of
the
filter. Fill the
sump
with the Correct amount
of
oil for your
engine. (Refer to the SYSTEM SPECIFICATIONS section
of
this manual.) Use an oil with an API specification
of
CF
or
CG-4. Run the generator and check for proper
oil
pressure
and make sure there are
no
leaks.
A
CAUTION:
Do
not
leave
the
engine's
old
lubricat-
ing
oil
in
the
sump
over
the
lay-up
period.
Lubricating
oil
and
combustion
deposits
combine
to
produce
harm-
ful
chemicals
which
can
reduce
the
life of
your
engine's
internal
parts.
Fuel
System
Top off your fuel tanks with
No.2
diesel fuel. Fuel additives
such
as
BioBor and Sta-Bil should be added at this time to
control algae and condition
the
fuel. Care should be taken
that the additives used
are
compatible with the primary fil-
ter/water separator used in the system. Change the element
in
your primary fuel filter/water separator, if the fuel system
contains one, and clean the separator sediment bowl.
Change the fuel filter
elements
on
the engine and bleed the
fuel system, as needed. Start the engine and allow
it
to run
for 5 -
10 minutes to
make
sure no air
is
left
in
the fuel sys-
tem. Check for any leaks that may have been created
in
the
fuel system during this servicing, correcting them as needed.
Operating the engine for
5-10
minutes will help allow move-
ment
of
the treated fuel through the injection equipment
on
the engine.
Raw
Water
Circuit
Close the through-hull
sea
cock. Remove the raw 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
clcan
or
replace
it
as required,
and also clean any zinc debris from inside the
heal exchanger
where the zinc anode is located. Clean the raw water strainer,
if
one
is
installed,
in
the inside
of
the hull.
Start the engine and allow the raw 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 raw water system.
Once
the bucket
is
empty, stop
the engine.
This
antifreeze mixture should protect the raw
water circuit from freezing during the winter lay-up, as well
as providing corrosion protection.
Remove the impeller from your raw 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
dean
cloth, lightly
soaked
in
lubricating oil,
in
the
opening
of
the intake manifold to block the opening.
Do
not
shove the cloth out
of
sight.
(If
it
is
not visible at recommis-
sioning, and an attempt is
made
to start the engine, you may
need the assistance
of
a
servicing
dealer.) Make a note to
remove the cloth prior to start-up.
The
through-hull exhaust
port
can be blocked
in
the
same
manner.
