7. Remove the outboard motor from the
test tank.
8. Drain the cooling water completely out
of the motor. Clean the body thoroughly.
9. Install the top cowling.
10. Fill the fuel tank with fresh fuel and add
one ounce of "Yamaha Fuel Conditioner
and Stabilizer" to each gallon of fuel.
TIP:
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.
11. Store the fuel tank in a dry, well-ventilat-
ed place, not in direct sunlight.

Lubrication

1. Install the spark plug(s) and torque to
proper specification. For information on
spark plug installation, see page 78.
2. Change the gear oil. For instructions,
see page 84. Inspect the oil for the pres-
ence of water that indicates a leaky seal.
Seal replacement should be performed
by an authorized Yamaha dealer prior to
use.
3. Grease all grease fittings. For further de-
tails, see page 77.
TIP:
For long-term storage, fogging the engine
with oil is recommended. Contact your
Yamaha dealer for information about fogging
oil and procedures for your engine.
