The American Boat and Yacht Council (ABYC) has
published a standard for the color coding of boat
wiring. Four Winns voluntarily complies with these
standards so the owner of the new boat can easily
install new equipment or troubleshoot the electrical
system. The following table summarizes the color
code system:

H - 5 STRAY CURRENT CORROSION
A. General
Electrically induced underwater corrosion occasionally
affects boats and their related components. This is
referred to as “Stray Current Corrosion” and appears
as surface pitting or deterioration. Stray current corro-
sion is the decomposition of chemical compounds by
electric current.
Stray current corrosion can be caused by the polarity
of the dockside wiring system of the boat being
reversed from the power source (reversed polarity)
or surrounding boats, an improperly wired battery
installation, other boats that are in close proximity that
have electrical power leakages, or any other source
close to the boat that has electrical power leakage into
the water. Stern drive units are especially vulnerable
to stray current corrosion.
Periodically inspect the drive components and
thru-hullttingstodetermineifstraycurrentcorrosion
damage exists. If corrosion damage is found,
determine and correct the cause of stray current
to prevent further damage. Consult an experienced
marine electrician or contact your Four Winns dealer
for assistance.
The use of some shore power battery chargers while
the boat is in the water and the battery is connected
to the system can cause stray current corrosion. Have
an experienced marine electrician review any battery
charger installation to ensure a stray current corrosion
problem will not develop. An improper battery connec-
tion is a common cause of stray current corrosion.
NOTICE
Use only UL Marine – ignition protected
battery chargers. Consult your Four Winns
Dealer for recommendations.
Corrosion is usually more prevalent in polluted or
s
alt water than in fresh water. It is also more likely
to occur when dockage is in an area with steel piers,
large metal boats, or where shore power is in use.
