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 trou- ble.
Store the outboard motor in a
dry, well- ventilated place, not in direct
sunlight.
Procedure
Flushing in a test tank
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 67.
2. Wash the outboard motor body using
fresh water. NOTICE: Do not spray
wa- ter into the air intake. [ECM01840] For
fur- ther information, see page 71.
3. Fill the fuel tank with fresh fuel and add
one ounce of “Hidea Fuel Conditioner
and Stabilizer” to each gallon of fuel.
TIP:
The use of “Hidea Fuel Conditioner and
Stabilizer” eliminates the need to drain the
fuel system. Consult your Hidea 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 engine top cowling and si-
lencer cover. Remove the propeller.
For
further details, see page 81.
6. Position the outboard motor on a water
tank. For further details, see page 37.

supply is insuffi- cient, engine
seizure may occur.

8. Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt. In addi-
tion, fogging of the engine is mandatory
to prevent excessive engine damage
due to rust. Perform the flushing and
fogging at the same time. WARNING!
Do not touch or remove electrical
parts when starting or during opera-
tion. Keep hands, hair, and clothes
away from the flywheel and other ro-
tating parts while the engine is run-
ning.
9. Run the engine at a fast idle for 10–15
minutes in neutral position.
10. Just prior to turning off the engine,
quick- ly spray “Hidea Stor-Rite Engine
Fogging Oil” alternately into each
carbu-
