Batteries
If batteries are to be left on board during the lay-up period, make sure 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 proce-
dures as those presented in the "PREPARATIONS FOR STARTING" section, page 33, 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 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.
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 make sure 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 ad-
verse affects.
5. Start the unIT in accordance with those procedures found in the "STARTING PROCEDURES" section of
this manual, page 34.
