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, the following proce-
dures can be performed by the owner.
NOTICE

● 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 valve and cause engine trouble.
● Transport and store the outboard motor
as specified in “Transporting/Dismount-
ing the outboard motor”.
● 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.
Cooling system flushing is essential to pre-
vent the cooling system from clogging up with
salt, sand, or dirt. In addition, fogging of the
engine is mandatory to prevent excessive en-
gine damage due to rust. Perform the flushing
and fogging at the same time.
