• The troll mode system will not operate if the
switch is depressed when the remote control

• When pressing the "DN" switch at the lower
limit of trolling speed of all engines, the
engine speed will not change and three long

• 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 rpm
or more. In both cases, two short (0.1 sec.)
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
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
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 temperatures stand it up in the
vertical position so that the cooling sys-
tem drains completely.
