Spares
Lay-up time provides a good opportunity to inspect the equipment 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.
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 no 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, 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.
WARNING
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 arcing 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 !iIlly
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 system.
When the input is put into operation, the system will self-flush in a short period of time with no adverse
effects.
5. Start the unit in accordance with procedures in the "Preparation for Starting" section of this manual.
