Adjusting Trolling Speed
• When pressing the "UP" switch, one short
beep sounds
increases by 50 r/min.
• When pressing the "DN" switch, one short
beep sounds
decreases by 50 r/min.
NOTE:
• When pressing the "DN" switch at the lower
limit of trolling speed of all engines, the
engine speed will not change and three long
beeps will sound.
• When pressing the "UP" switch at the upper
limit of trolling speed of all engines, the
engine speed will not change and three long
beeps will sound.
• For the multiple engines:
If the switch is operated when one engine
has reached the adjustment limit of trolling
speed, while any other engine has not, one
short beep sounds and the rpm of engine
which has not reached the adjustment limit
changes.
• Shift operation and throttle control remain
operational, even in troll mode.
Cancelling the Troll mode:
The troll mode can be cancelled by shifting the
all remote control levers to the neutral position,
or by increasing the engine speed to 3000 r/min
or more. In both cases, two short beeps sound
when cancelling the troll mode.
OPERATION IN SALT WATER
After operating the motor in salt water, you
should flush the water passages with clean,
fresh water as outlined in the FLUSHING THE
WATER PASSAGES section. If you do not flush
the water passages, salt can corrode the motor
and shorten its life.

OPERATION IN FREEZING WEATHER
When operating your outboard motor in freez-
ing temperatures, you should keep the lower
speed
unit submerged in the water at all times.
When taking motor out of the water, stand it up
in a vertical position until the cooling system
speed
drains completely.
If you leave your outboard motor out of the
water in freezing temperatures with water still
in the cooling system, the water can freeze
and expand, causing severe damage to the
motor.
When your outboard is in the water in freezing
temperatures, keep the lower unit submerged
in the water at all times. When the motor is
stored out of the water in freezing tempera-
tures stand it up in the vertical position so
that the cooling system drains completely.
