LAY·UP & RECOMMISSIONING
Starter Motor
Lubrication and cleaning of the starter drive pinion is 'advisable,
if access to the starter pennits 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 [Diesel]
If you anticipate a long lay-up period (12 months or more)
WESTERBEKE recommends removal of the glow plugs for
access to the cylinders. Squirt some Marvel Mystery Oill into
the cylinder walls. Rotate the engine crankshaft by hand two
revolutions and re-install the glow plugs.
If your engine does not have glow plugs, the injectors will have
to be removed. Be sure to have replacement sealing washers for
the injectors and return fuel line as needed.
Intake Manifold [Gasoline]
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!
Cylinder Lubrication [Gasoline 1
After engine shutdown, remove the spark plugs and spray a
small amount of fogging oil into each cylinder. Rotate the
crankshaft manually two complete revolutions. Re-install the
spark plugs loosely for winter lay-up
NOTE: At spring commissioning, remove theplugs and rotate
the crankshaft two full revolutions. Re-install the spark plugs,
tighten properly and connect. the high tension leads fully onto
each spark plug. ·
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 tbey will be
subjected
to severe enVironmental conditions, remove the
batteries
and store thern.in a warmer, more compatible
environment.

A WARNING: Lead acldlJaltiiles iiilliiil'yilrogen, a
hll/hly.;exp/osive gas~ which can m·ignlted by electrical
arcing or a light8d cigarene, cigar, or pl(ie. ~D.o :n~t
smoke or allow an open 1/ame near the battery being
$erviced. Shllf off all electrical equipment in the vicinity
to prevent e/ectilcal arcing during servicing.
Transmission [Propulsion Engine]
Check or change the fluid in the transmission as required Wipe
off grime and grease and touch up any unpainted areas. Protect
the coupling and the output flange with an anti-corrosion
coati..ng. Check that the. transmission vent is open. For
additional infonnation; refer to the TRANSMISSION SECTION.
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 PAI?TS section of this manual.
Recommissioning
·The recommissioning of your Westerbeke engine after a
seasonal lay-up generally follows the same procedures as
those described in the PREPARATJONSFOR.STARTING
section regarding preparation for starting and nonnal starts.
However, some of the lay-up procedures will need to be
counteracted before starting the engine.
1. Remove the oil-soaked cloths from the intake manifold.
2. Remove t):le raw water pump cover and gasket and
discard the old gasket. Install the raw water pump impeller
removed during lay-up {or a replacement, if required).
Install the raw water pump cover with a new cover gasket.
3. Reinstall the batteries that were removed during the '
lay-up, and reconnect the battery cables, making sure the
tennlnals are clean and that the connections are tight
Check to make sure that the batteries are fully charged.
A CAUTION: Wear rubber gloves, a rttbber apron,
and eye protection when servicing batteries. Lead acid
batteries emit hydrogen, a highly explosive gas, which
can be ignited by electrical arcing or a lighted
cigarene~ cigar, or pipe. Do not smoke or allow an open
flamf,1 near the baftery being serviced. Shut off all
electrical equipment in the Vicinity to prevent electrical
arcing during servicing.
4. Remove the spark plugs, wipe clean, re-gap, and install to
proper tightness [gasoline].
5. Check the condition of the zinc anode in the raw water
circuit and clean or replace the anode as needed. Note
· that it is not necessary to flush the antifreeze/fresh water
solution from the raw water coolant system. When the
engine is put into operation, the system will self-flush in a
short
period of time with no adverse affects. It is
advisable, as either an end of season or recommissioning
service, to inspect the area where the zinc is located in the
heat exchanger and clear any and all zinc debris from that
·area.
6. Start the engine in accordance with procedures described
in the PREPARATIONS FOR STARTING section of this
manual.
