FRESH-WATER COOLING SYSTEM
SACRIFICIAL ZINC ANODE
Located in the raw water side of the heat exchanger is
a zinc anode which is marked by a decal. To check,
remove the plug and visually check the condition of
the zinc rod. The length of the zinc rod when new is
approximately 1.5 inches. If more than one half of the
zinc is gone, replace with a new zinc anode.
Different geographic locations and water make-up can
result in either high or low sacrifi cial requirements. A
high rate of zinc anode consumption should also alert
the owner to a possibility of an improperly wired boat
accessory, which would require complete checking by
qualifi ed service personnel.
