odic maintenance.

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

cable to the battery positive (+) post FIRST. Con-
nect the battery negative (-) cable to the battery

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 Triple-
Guard grease to prevent corrosion.
Battery Cable 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.
