Storing outboard motor
When storing your Yamaha outboard motor
for prolonged periods of time (2 months or
longer), several important procedures must
be performed to prevent excessive damage.
It is advisable to have your outboard motor
serviced by an authorized Yamaha dealer pri-
or to storage. However, you, the owner, with a
minimum of tools, can perform the following
procedures.
NOTICE
ECM01080
● To prevent problems which can be
caused by oil entering the cylinder from
the sump, keep the outboard motor in
the attitude shown when transporting
and storing it. If storing or transporting
the outboard motor on its side (not up-
right), put it on a cushion after draining
the engine oil.
● Do not place the outboard motor on its
side before the cooling water has
drained from it completely, otherwise
water may enter the cylinder through the
exhaust port and cause engine trouble.
● Store the outboard motor in a dry, well-
ventilated place, not in direct sunlight.

Flushing in a test tank
NOTICE
ECM00301
Before starting the engine, make sure to
supply water to the cooling water passag-
es. Otherwise, the engine could overheat
and be damaged.
1. Wash the outboard motor body using
fresh water. NOTICE: Do not spray wa-
ter into the air intake.
[ECM01840] For further
information, see page 57.
2. Disconnect the fuel line from the motor or
shut off the fuel cock, if equipped.
3. Remove the engine top cowling and si-
lencer cover. Remove the propeller.
4. Install the outboard motor on the test
tank. Fill the tank with fresh water to
above the level of the anti-cavitation
plate. NOTICE: If the fresh water level
is below the level of the anti-cavitation
plate, or if the water supply is insuffi-
cient, engine seizure may occur.

5. Cooling system flushing is essential to
prevent the cooling system from clogging
up with salt, sand, or dirt. In addition, fog-
ging/lubricating of the engine is mandato-
ry to prevent excessive engine damage
due to rust. Perform the flushing and fog-
ging at the same time. WARNING! Do
not touch or remove electrical parts
when starting or during operation.
Keep hands, hair, and clothes away
from the flywheel and other rotating
parts while the engine is running.
