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 trou-
ble.
Store the outboard motor in a dry, well-
ventilated place, not in direct sunlight.
Drain the remaining gasoline from the
vapor separator. Gasoline left in the va-
por separator for a prolonged period of
time will break down and could cause
damage to the fuel line.

Flushing with the flushing attachment
ECM02131
Do not run the engine without supplying
it with cooling water. Either the engine
water pump will be damaged or the en-
gine will be damaged from overheating.
Cooling system flushing is essential to pre-
vent the cooling system from clogging up
with salt, sand, or dirt. In addition, fogging/lu-
bricating of the engine is mandatory to pre-
vent excessive engine damage due to rust.
Perform the flushing and fogging at the same
time.
(1) Wash the outboard motor body using
fresh water.
NOTICE:
Do not spray wa-
ter into the air intake.

ther information, see page 70.
(2) Disconnect the fuel line from the out-
board motor.
(3) Remove the engine top cowling, fly-
wheel cover, and propeller. For further
details, see page 82.
(4) Install the flushing attachment over the
cooling water inlet.
NOTICE:
Do not run
the engine without supplying it with
cooling water. Either the engine water
pump will be damaged or the engine
will be damaged from overheating.
Before starting the engine, be sure to
supply water to the cooling water
passages. Avoid running the out-
board motor at high speed while on
the flushing attachment, otherwise
overheating could occur.

TIP:
A flushing attachment is available from
your Yamaha dealer.
When using the flushing attachment, main-
tain adequate water pressure and a steady
water flow.
(5) Run the engine at a fast idle for a few
minutes in neutral position.
