3. Operation Note: The engine may be s topp ed by pulling out the decompression lever, but avoid doing so except in times of emergency. In this case, the engine is stopped by cutting off the air pressure. How- ever, fuel injection does not stop, and fuel ls leftover in the combustion chamber. This will lead to abnormal combustion when the engine is restarted and is not desirable. 3.4 Long Term Storage (1) In cold temperatures or before long Water drain cock @Sea water pump term storage, be sure to drain the water @ Loosen bolts and pull out top from the seawater cooling system. 1. Loosen the drain cocks at the side of the cylinder block, and drain off the A CAUTION water inside. 2.
Loosen the 6 bolts fixing the side cover of the seawater pump, remove the cover and drain the water from inside. Retighten the bolts when finished. 3. Close the drain cocks. Drain water from the cooling system after the engine has coo led down. Be careful to avoid burns. I l If water is left inside, it may freeze and damage parts of the cooling system (fresh water cooler, sea- water pump, etc.) (2) If antifreeze has not been added to the cooling fresh water, be sure to drain off the water from the fresh water cooling system daily after use.
Fresh Water Cooling If the water is not r emoved, it may freeze and damage parts of the cooling water system (fresh water cooler, cylinder block , cylinder head, etc .) 32
