Connect the battery cables:
1. Connect the cable with the red
terminal cover to the positive ( + )
terminal of the battery.
2. Connect the cable with the black
terminal cover to the negative ( – )
terminal of the battery.
When more than one outboard motor
is mounted on a boat, connect a
battery to each respective outboard
motors.
• Be sure to connect the ( + ) side
battery cable first. When
disconnecting the cables,
disconnect the ( – ) side first then
the ( + ) side.
• Unless the cables are properly
connected to the terminals, the
starter motor may fail to operate
normally.
• Be careful to avoid connecting
the battery in reverse polarity,
as this will damage the
battery-charging system in the
outboard motor.
• Do not disconnect the battery
cables while the engine is
running. Disconnecting the
cables while the engine is
running, will damage the
outboard motor's electrical
system.
• Do not place the fuel tank near
the battery.
INSTALLATION
• Battery cable extension:
Extending the original battery
cable will cause the battery
voltage to drop due to the
increased length of the cable and
number of connections. This
voltage drop may cause the
buzzer to sound momentarily
when engaging the starter motor
and may prevent the outboard
from starting. If the outboard
starts and the buzzer sounds
momentarily, there may be
barely sufficient voltage
reaching the engine.
