6.11 Bonding System
Your boat is equipped with a bonding system that
interconnects the underwater metal hardware
and the engines to ensure that they are of the
same electrical potential. Sacricial anodes of
the size and type recommended by the engine
manufacturer are attached to the outboard motor.
There is also an anode on the transom and could
be anodes on each trim tab plane. The trim tab
anodes are isolated from the boat bonding system
to protect each tab plane assembly if the boat is
to kept in saltwater.
Anodes deteriorate before other metals, thereby
protecting the underwater metals from galvanic
corrosion or stray electrical current. Since anodes
are sacricial, it is important to monitor them and
replace them when they have deteriorated to 50
- 75% of their original size.
The bonding system is connected to the engine
and battery DC ground. The earth ground wire
for the battery charger and AC electrical system is
also connected to the bonding system. It provides
a path to the safety earth ground in the event of
a fault in the shore earth ground connection.
6.12 Electrical System Maintenance
DC Electrical System Maintenance
At least once a year, spray all exposed electrical
components behind the helm, in the stern bilge
area and in the plugs with a protector. Remov-
able light xture bulbs should be removed and
the metal contact areas coated with a non-water
soluble lubricant like Teon or Silicone grease.
The sockets should be sprayed with a protector.
Care must be taken not to get any oil or grease
on the glass portion of the bulbs as this will cause
the bulb to overheat and burn out.
Notice:
Most LED light xtures are sealed and not
serviceable.
WHEN REPLACING LIGHT BULBS IN MARINE LIGHT
FIXTURES, ALWAYS USE A BULB WITH THE SAME RATING AS
THE ORIGINAL. USING A DIFFERENT BULB COULD CAUSE
THE FIXTURE TO OVERHEAT AND MELT OR SHORT CIRCUIT.
Check all below deck wiring to be sure it is properly
supported, that the insulation is in good condition

and that there are no loose or corroded terminals.
Corroded terminals should be thoroughly cleaned
with sandpaper or replaced, tightened securely
and sprayed with a metal and electrical protector.
Inspect all engine wiring.
Your boat is equipped with batteries that were sup-
plied by your dealer. Some batteries are sealed,
AGM or maintenance free wet cell batteries that
do not require inspection or service. However, if
your boat is equipped with standard wet cell type
batteries that are not maintenance free, they will
require the following inspection and service.
Check the electrolyte level in the batteries regu-
larly and add distilled water as necessary. If the
