Batteries
If batteries are to be left on board during the lay-up period, ensure that they are fully charged, and will remain
that way, to prevent them from freezing. If there exists 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.
Recommissioning
The recommissioning of your Westerbeke unit after a seasonal lay-up generally follows the same procedures
as those presented in the "Preparation for Starting" section, page 14, regarding preparation for starting and
normal starts. However, some of the lay-up procedures will need to be counteracted before starting the en-
gine.
1. Remove the oil-soaked cloths from the intake manifold and from the through-hull exhaust port.
2. Remove the sea water pump cover and gasket. Discard the gasket. Install the sea water pump impeller
removed during lay-up (or a replacement, if required). Install the sea water pump cover with a new cover
gasket.
IWARNINGI
Wear rubber gloves, a rubber 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 cigarette, cigar, or pipe. Do not smoke or allow an open flame near the
battery being serviced. Shut off all electrical equipment in the vicinity to prevent electrical ar-
cing during servicing.
3. 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 ensure that the batteries are fully-
charged.
4. Check the condition of the zinc anode in the sea 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 sea water coolant sys-
tem. When the unit is put into operation, the system will self-flush in a short period of time with no adverse
affects.
5. Start the unit in accordance with those procedures found in the "OPERATION" section of this manual.
