Procedure

Flushing with the flushing attachment
1.
Wash the outboard motor body using
fresh water. For further information, see
page 55.
2. Fill the fuel tank with fresh fuel and add
one ounce of “Yamaha Fuel Conditioner
and Stabilizer” (Part No. LUB-FUELC-12-
00) to each gallon of fuel.
NOTE:
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.
3. Remove the top cowling and propeller.
4. Install the flushing attachment over the
cooling water inlet.
CAUTION:
ECM00300
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 wa-
ter to the cooling water passages.
CAUTION:
ECM00310
Avoid running the outboard motor at high
speed while on the flushing attachment,
otherwise overheating could 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
EWM00090
● 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.
NOTE:
● When using the flushing attachment, main-
tain adequate water pressure so that there
is a steady flow of water from the cooling
water pilot hole.
● If the overheat warning device is activated,
turn the engine off, and consult your
Yamaha dealer.
