Section 2 Boat Operation
Battery Parallel Switch
Your boat is equipped with an emergency battery par-
allel switch. The switch is located at the helm station.
You can use the emergency battery parallel switch to
connect the two engine starting batteries in parallel if
one engine will not start due to low battery voltage.
The battery parallel switch controls a solenoid that
connects the two engine starting batteries. The switch
is a 3-position rocker switch that is ON-OFF-ON. The
center switch position is OFF. Both the left and right
switch positions are momentarily ON when held down.
When you release the switch, it will return to the center
OFF position.
If one of your outboard engines will not start due to low
battery voltage, use the emergency battery parallel
switch to provide power from the other starting battery.
Push and hold the battery parallel switch ON to either
the left or right position. Note this position. Hold the
battery parallel switch in the ON position and try to
start the engine.
If the engine does not start, release the battery parallel
switch to the OFF position. Move the battery parallel
switch to ON in the opposite direction. Hold the bat-
tery parallel switch in the ON position and try to start
the engine.
