the engine at a fast idle until the fuel sys-
tem becomes empty and the engine
stops.
11. Drain the cooling water completely out
of the motor. Clean the body thoroughly.

Lubrication (oil injection models)

1. Grease the spark plug threads and in-
stall the spark plug(s) and torque to
proper specification. For information on
spark plug installation, see page 49.
2. Fill the oil tanks. This prevents the for-
mation of condensation. For models with
a remote oil tank, it may be necessary to
manually override the control unit to
completely fill the engine oil tank.
3. Change the gear oil. For instructions,
see page 56. Inspect the oil for the pres-
ence of water which indicates a leaky
seal. Seal replacement should be per-
formed by an authorized Yamaha dealer
prior to use.
4. Grease all grease fittings. For further de-
tails, see page 49.
