Requirements
EvinrudelJohnson outboards are shipped with
stranded copper battery
cables for typical installa-
tions
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
table below.
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.
