Don2t remove the water pump impeller. Change the impeller when you recommission, or you may loose some of the water/antifreeze mix. If you have an indirect cooling system, it2s not a bad idea to flush the sea water part as above, but the thermostat doesn2t have to be open - that2s in the freshwater. Sea water remaining in the system could freeze in very low temperatures and draining the system isn2t always fully effective. AIR SYSTEM Disconnect the exhaust hose from the engine and check its condition. Remove air cleaner(s) from the engine. Spray water repellent oil up exhaust and air intakes and then seal with plastic bags to prevent damp air entering. ELECTRICS The battery needs to be recharged monthly so take it home if necessary.

ANODES As well as any anodes in the cooling system, it2s essential that sail drive anodes are checked.
