ECM00301
NOTICE
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.
1. Wash the outboard motor body using
fresh water. NOTICE: Do not spray wa-
ter into the air intake.
information, see page 52.
2. Fill the built-in fuel tank with fresh fuel and
add one ounce of "Yamaha Fuel Condi-
tioner and Stabilizer" to each gallon of fu-
el.
TIP:
The use of "Yamaha Fuel Conditioner and
Stabilizer" eliminates the need to drain the
fuel system. Consult a Yamaha dealer or oth-
er qualified mechanic if the fuel system is to
be drained instead.
3. When using a portable fuel tank, discon-
nect the fuel hose, install the fuel joint
cap, and then align the fuel cock with the
built-in fuel tank position.
