LAY-UP & RECOMMISSIONINGINTAKE MANIFOLDClean the filter screen in the flame arrester, and place a cleandoth lightly soaked in lube oil around the flame arrester toblock any opening. Also place an oil-soaked cloth in thethrough-hull exhaust port. Make a note to remove cloths prior tostart-up!STARTER MOTORLubrication and cleaning of the starter drive pinion is advisable,if access to the starter permits its removal. Make sure the batteryconnections are shut off before attempting to remove thestarter. Take care in properly replacing any electrical connectionsremoved from the starter.CYLINDER LUBRICATIONSpray fogging oil into the open air intake, with the flamearrestor removed, while the generator is running. The foggingoil will stall out the engine and coat the valves, cylinders andspark plugs for winter protection.NOTE: The spark plugs will need to be removed for cleaningand regapping at spring commissioning.SPARE PARTSLay-up time provides a good opportunity to inspect yourWESTERBEKE engine to see if external items such as drivebelts or coolant hoses need replacement. Check your basicspares kit and order items not on hand, or replace those itemsused during the lay-up, such as filters and zinc anodes.RECOMMISSIONINGThe recommissioning of your WESTERBEKE engine after aseasonal lay-up generally follows the same procedures asthose presented in the PREPARATIONS FOR INITIAL STARTUP section regarding preparation for starting and normalstarts. However, some of the lay-up procedures will need tobe counteracted before starting the engine.1. Remove the oil-soaked cloths from the intake manifoldand from the through-hull exhaust port.2. Remove the raw water pump cover and gasket. Discard thegasket. Install the raw water pump impeller removed duringlay-up (or a replacement, if required). Install the rawwater pump cover with a new cover gasket.3. Remove the spark plugs, wipe clean, re-gap, and install toproper tightness.4. Reinstall the batteries that were removed during the layup,and reconnect the battery cables, making sure the terminalsare clean and that the connections are tight. Checkto make sure the batteries are fully charged.5. Note that it is not necessary to flush the antifreeze/freshwater solution from the raw water coolant system. Whenthe engine is put into operation, the system will self-flushin a short period of time with no adverse affects.6. Start the engine in accordance with procedures in thePREPARATIONS FOR INITIAL SDlRT-UP section of thismanual.BATTERIESIf batteries are to be left on ·board during the lay-up period,make sure that they are fully charged, and will remain thatway, to prevent them from freezing. If there is any doubt thatthe batteries will not remain fully charged, or that they willbe subjected to severe environmental conditions, remove thebatteries and store them in a wanner, more compatible environment.A WARNING: Lead acid batteries emit hydrogen, ahighly·explosive gas, which can be ignited by electri·cal arcing or a lighted cigarette, cigar, or pipe. Do notsmoke or allow an open flame near the battery beingserviced. Shut off all electrical equipment in thevicinity to prevent electrical arcing during servicing.Engines & Generators35
