(c) Grounding the battery negative
It is recommended that the battery negative busbar should be grounded as close as possible to the battery, by
a substantial connection to the bonding system within the boat. This will reduce the likelihood of interference
between items of electrical and electronic equipment tted to the boat.
(d) Battery isolator switches
A switch should be tted in the positive lead to the starter, as close to the battery as is convenient. The switch
should be suitable for a momentary current of at least 1000 Amps.
7.7 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.
(a) 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 that may be used for this
purpose, see, ‘Location of engine installation points’ at the beginning of this manual, for location of the stud.
The stud is identied by a label, shown below:
BOATBUILDER
Use this stud to connect the
engine to the Zinc Anode system
installed in the boat.
