WARNING
~
Keep the battery
connections
clean, tight,
and insulated
to
prevent
their
shorting
or
arcing and causing an explosion. If
the
battery mounting system
does
not
cover
the connections, install protective covers.
Check often
to
see that
connections
stay
clean and tight.

IMPORTANT:
Do
not use wing nuts to fasten
ANY battery
cables. Wing nuts can loosen and
cause
electrical system damage not covered
under warranty.
Tighten
all
connections securely. Apply Trip/e-
Guard grease to prevent corrosion.
Battery Cable Requirements
Evinrude/Johnson electric start outboards are
shipped with stranded copper battery
cables for
typical installations
in
which the starting battery
is
positioned close
to
the transom.
Specialized outboard installations with extended
length battery cables require
an
increased wire
size. Refer
to
the following table:
Cable Size
Cable
Length
6 Gauge
1
to
10
ft.
(0.3 to 3
m)
4 Gauge
11
to
15
ft.
(3.4 to 4.6
m)
3 Gauge 16
to
20
ft.
(4
.9
to
6.1
m)
IMPORTANT: Inadequate battery cables can
affect the performance of
an
outboard's high
amperage start circuit
and
the cranking speed of
the outboard.
DO
NOT use aluminum wire cables.
Use ONLY
AWG
stranded copper wire cables.
