Zinc Anode bonding system
Caution: The engine may be damaged by electrolytic
corrosion if the correct bonding procedure is not
adopted. Please read the guidelines below carefully.
Electrolytic corrosion within the engine cooling system
and transmission can be much reduced or eliminated
by bonding the engine to a Zinc anode which is used
to protect through the hull metal ttings and other
metal components that are in contact with sea water.
The engine is tted with a stud (gure 29 item 1) that
may be used for this purpose and is identied by a
label as shown in gure 30.
BOATBUILDER
Use this stud to connect the
engine to the Zinc Anode system
installed in the boat.
