BATTERY INSTALLATION

Battery Cable Requirements

Evinrude outbo ards are shippe d with stranded
copper bat tery ca bles for typical inst allations in
which the starting battery is close to the transom.
Specialized outb oard inst allations with e xtended
length ba ttery cable s require an increased wire
size. Refer to the following table.
15–30 HP
1 to 10 Ft. 6 Gauge
(.3 to 3 m)
11 to 15 Ft. 4 Gauge
(3.4 to 4.6 m)
16 to 20 Ft. 2 Gauge
(4.9 to 6.1 m)
Inadequate ba ttery cables can
IMPORTANT:
affect the performance of an outb
amperage start circuit and th e 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 batte ry
selector switches, can provide fle xibility i n sing le
and dual outboard installations.
Refer to Battery and Switch Wiring Diagrams
on p. 18 for battery connection options.
The battery selection function can be used for
emergency starting if a primary bat tery become s
discharged.
The OFF po sition o f the batte ry sele ctor switch
can be used to minimize battery discharge during
periods of non-use.
Typical battery functions
Primary
Used as starting battery under normal operating
•
conditions.
Red (+) cable connected to battery switch.
•
Primary battery is charge d by conne ction to
•
main red (+) outboard battery cable.

Dual outboard installations can utilize the oppos-
ing outboard's primary battery as a secondary bat-
tery for emergency starting only.
Secondary
Used as back-up st arting batter y un der abn or-
•
mal operating conditions.
Red (+) cable connected to battery switch.
•
Secondary b attery is

from primary battery.
40–300 HP
Accessory
4 Gauge
Not used as starting battery.
•
Isolated from outboard start function.
•
2 Gauge
No red (+) cable connected to battery switch.
•
Secondary and accessory batte ries are

charged by an iso lated batte ry ch arging circuit.
Refer to Auxiliary Battery Charging on p. 17.
Battery Switch Requirements
oard's high
Battery switches must mee t the followin g require-
ments.
The switch must be approved for marine use.
•
The switch sh ould be a "make
•
design.
Switch amperage rating should be adequate for
•
the outboard it will be used on.
Use one batt ery switch
•
installed.
Use appropriately sized wire and terminals.
•
Use AWG stranded copper wire.
•
Battery Switch Location
Locate battery switch as close t o the bat teries
•
as possible.
Locate swit ch so that it cannot be accid ently
•
bumped or switched.
Refer to the battery
•
installation instructions.
Fasten all battery switches to solid surfaces.
•
Route wiring as directly as possible.
•
Support the battery switch as needed to prevent
•
abrasion.
Use appropriate wiring and connectors.
•
Seal all connections an d te rminals with liquid
•
neoprene to prevent corrosion.
