LAY-UP
&
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 perform your
own lay-up and recommissioning, or you may use them as a
check list
if
others do the procedures.
These procedures should afford your engine protection
during a lay-up and also help familiarize you with the
maintenance 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.
CYLINDER/SPARK
PLUGS
Spray fogging oil into the open air intake, with the flame
arrester removed, while the engine is running. The fogging
oil will stall the engine and coat the intake components,
valves, cylinders and spark plugs for winter protection.
NOTE:.
At re-commissioning,
remove
the
spark plugs
and
clean and gap
them.
Rotate
the
engine by hand
two
complete
revolutions. Re-install
the
spark plugs and tighten securely
and firmly attach the high tension
Zeds.
LUBRICATION
SYSTEM
With the engine warm, drain all the lubricating oil from the
oil sump. Remove and replace the oil filter and fill the sump
with new oil.
Use the correct grade
of
oil. Refer to the
ENGINE LUBRICATING OIL pages in this manual for the
oil changing procedure. Run the engine make sure there are
no leaks.
A
CAUTION:
Do
not
leave
the
engine's
old
engine
oil
in
the
sump
over
the
lay-up
period.
Lubricating
oil
and
combustion
deposits
combine
to
produce
harmful
chemicals
which
can
reduce
the
life
of
your
engine's
internal
parts.
Recommissioning
The recommissioning
of
your Westerbeke engine after a
seasonal lay-up generally follows the same procedures as
those described in the
PREPARATIONS FOR STARTING
section regarding preparation for starting and normal starts.
However, some
of
the lay-up procedures will need
to
be
counteracted before starting the engine.
1.
Remove any rags that were placed in the exhaust, intake
manifold,
or
flame arrester.
2. Reinstall the batteries that were removed during the
lay-up, and reconnect the battery cables, making sure the
terminals are clean and that the connections are tight.
Check
to
make sure that the batteries are fully charged,
remove the sparl plugs, wipe clean, re-gap, and install to
proper tightness.
3.
Make certian the cooling system intake hose is attached
INTAKE
MANIFOLD
Clean the filter screen in the flame arrester, and place a clean
cloth lightly soaked in lube oil around the flame arrester to
block any opening. Also place an oil-soaked cloth in the
through-hull exhaust port, Make a note to remove cloths
prior to start-up!
FUEL
SYSTEM
Top off your fuel tanks with unleaded gasoline
of
89 octane
or higher. A fuel conditioner such as stabil gasoline stabilizer
should be added. Change the element in your gasoline/water
separator and clean the metal bowl. Re-install and make
certain there are
no
leaks. Clean up any spilled oil.
STARTER
MOTOR
Lubrication and cleaning
of
the starter drive pinion is
advisable, the pinion is accessible when the flywheel cover is
removed. 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.
SPARE
PARTS
Lay-up time provides a good opportunity to inspect your
Westerbeke engine 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
of
this manual.
BATTERIES
If
batteries are to
be
left on board during the lay-up period,
make sure that they are fully charged, and will remain that
way, to prevent them from freezing.
If
there is any doubt that
the batteries will not remain fully charged, or that they will
be subjected to severe environmental conditions, remove the
batteries and store them in a warmer, more compatible
environment.
4.
Check the conditton
of
the heat exchanger zinc, clean or
replace as needed.
5. Make certain all electrical connections and switches are
in the correct position and there are no-loads
on
the
generator at start-up (see
GENERATOR).
6. Inspect the fresh water pump impeller, replace
if
necessary.
7. Start the engine in accordance with the procedures
described in the
PREPARATIONS
FOR
STARTING
section
of
this manual.
and the thru-hull valve is open. .
