Procedure

EMU39602

Flushing in a test tank

NOTICE

ECM00301

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.

[ECM01840] For further

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.

IP:

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.

4. Remove the top cowling and fogging hole

cap.

5. Remove the propeller. For further infor-

mation, see page 61.

6. Install the outboard motor on the test

tank.
