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.

NOTICE

Before starting the engine, make sure to
supply water to the cooling water passag-
es. Otherwise, the engine could overheat
and be damaged.
1. Dismount the outboard motor from the
boat. For further details, see page 72.
2. Wash the outboard motor body using
fresh water. NOTICE: Do not spray wa-
ter into the air intake.
[ECM01840] For further
information, see page 77.
3. Fill the fuel tank with fresh fuel and add
one ounce of “Yamaha Fuel Conditioner
and Stabilizer” to each gallon of fuel.
TIP:
The use of “Yamaha Fuel Conditioner and
Stabilizer” eliminates the need to drain the
fuel system. Consult your Yamaha dealer or
other qualified mechanic if the fuel system is
to be drained instead.
4. Disconnect the fuel hose from the fuel
joint on the outboard motor and install the
fuel joint cap.
5. Remove the top cowling and silencer
cover (if equipped). Remove the propel-
ler. For further details, see page 87.
6. Position the outboard motor on a water
tank. For further details, see page 39.
