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 a qualified service technician can install
new equipment or troubleshoot the electrical system.
The following table (Figure H14) summarizes the color
code system:

STRAY CURRENT CORROSION
A. General
Electrically induced underwater corrosion occa sionally
affects boats and their related compo nents. This is
referred to as "Stray Current Corrosion" and appears
as surface pitting or deteri oration. Stray current
corrosion is the de composi tion of chemi cal com-
pounds by electric current.
g
o
o t
Stray current corrosion can be caused by the polarity
of the dockside wiring system of the boat being
e
reversed from the power source (re versed polarity) or
surrounding boats, an improp erly wired battery
i o
. d
installation, other boats that are in close proximity that
have electrical power leakag es, or any other source
s
e
o
r
close to the boat that has electri cal power leakage into
the water. Stern drive units are especially vulnerable
d
e
r
t
o
to stray current corrosion.
Periodi cally in spect the drive compo nents and thru-
hull fittings to determine if stray current corrosion
damage exists. If corrosion damage is found, deter-
W
i
e r
mine and correct the cause of stray current to prevent
u
t
o i
n
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
e
n
d
r e
the system can cause stray current corrosion. Have
an experienced marine electri cian review any battery
d
r e
o t
charger installation to ensure a stray cur rent corrosion
problem will not devel op. An improper battery connec-
o t
u f
l e
tion is a com mon cause of stray cu rrent corrosion.
Use only UL Marine – ignition protected
battery charg ers. Consult your Four Winns
Dealer for recommendations.
Corrosion is usually more prevalent in polluted or salt
water than in fresh water. It is also more likely to occur
when dock age is in an area with steel piers, large
metal boats, or where shore power is in use.
