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 48.

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 54. 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 48.

WARNING

Battery electrolytic fluid is dangerous; it contains sulfuric acid and therefore is poisonous and highly caustic.

Always follow these preventive mea- sures:

●Avoid bodily contact with electrolytic fluid as it can cause severe burns or permanent eye injury.

●Wear protective eye gear when han-

dling or working near batteries. Antidote (EXTERNAL):

●SKIN - Flush with water.

●EYES - Flush with water for 15 minutes

and get immediate medical attention. Antidote (INTERNAL):

●Drink large quantities of water or milk followed by milk of magnesia, beaten egg, or vegetable oil. Get immediate medical attention.

Batteries also generate explosive hydrogen gas; therefore, you should always follow these preventive measures:

●Charge batteries in a well-ventilated ar- ea.

●Keep batteries away from fire, sparks, or open flames (for example: welding equipment, lighted cigarettes, and so on.)

●DO NOT SMOKE when charging or han- dling batteries.

KEEP BATTERIES AND ELECTROLYTIC FLUID OUT OF REACH OF CHILDREN.

Batteries vary among manufacturers. Therefore the following procedures may not always apply. Consult your battery manufacturer’s instructions.

Procedure

1.Disconnect and remove the battery from the boat. Always disconnect the black negative cable first to prevent the risk of shorting.

2.Clean the battery casing and terminals. Fill each cell to the upper level with dis- tilled water.

3.Store the battery on a level surface in a cool, dry, well-ventilated place out of di- rect sunlight.

4.Once a month, check the specific gravity of the electrolyte and recharge as re-

quired to prolong battery life.
