INSTALLATION AND PREDELIVERY
BOAT RIGGING
Connections
IMPORTANT: Connect the battery positive (+)
cable to the battery positive (+) post FIRST. Con-
nect the battery negative (–) cable to the battery
negative (–) post LAST.
Install a starwasher on the threaded battery post.
Stack cables from the outboard, then cables from
accessories. Finish this connection with a hex nut.
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
Evinrude 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.
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.
Battery Switches and Multiple
Batteries
A multiple battery setup, including marine battery
selector switches, can provide flexibility in single
and dual outboard installations.
Refer to Battery and Switch Wiring Diagrams
on p. 33 for various battery connection options.
The battery selection function can be used for
emergency starting if a primary battery becomes
discharged.
The OFF position of the battery selector switch
can be used to minimize battery discharge during
periods of non-use.
