Oil level warning lamp
If the oil remaining in the tank drops to
about 1.2 L (0.31 US gal, 0.26 Imp gal) or
the oil filter is clogged, the oil level warning
lamp begins to blink.
If the oil level warning lamp begins to
blink, refill with engine oil as soon as possi-
ble.
NOTE:
●The lamp will light up for 2 seconds after
starting the engine to check the lamp
operation.
●If the warning lamp blinks with adequate
oil in the tank, check for a clogged oil fil-
ter.

Pre-operation checks
Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the
accompanying text in this chapter for details on how to perform the checks.
WARNING
If any item in the pre-operation check list is not working properly, have it inspected
and repaired before operating the watercraft, otherwise an accident could occur.

Pre-operation checks should be made thoroughly each time the watercraft is used. This pro-
cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

Pre-operation check points
Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove all seats and the front storage com-
partment. (See pages 2-4 and 2-5 for front
and rear seat, and 2-13 for front storage
compartment.) Allow the engine compart-
ment to remain open for a few minutes to
allow any fuel vapors to escape. Also, check
for loose electrical connections.
WARNING
Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or a loose electrical connection.
EJU00427-30a
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-9 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove all seats and the front storage
compartment. (See pages 2-4 and 2-5
for front and rear seat, and 2-13 for front
storage compartment.)
3. Check the fuel and oil levels in the tanks
and add as necessary. (See pages 3-3
and 3-4 for filling instructions.)

Inspecting the oil injection
system
Check the oil injection system for leakage,
cracks, or malfunctions. If necessary, have a
Yamaha dealer repair the oil injection sys-
tem.
Check:
●Oil tank for damage, cracks or leakage.
●Oil tank for water or dirt.
●Oil hose and joint for damage or cracks.
●Oil filter for dirt.
●Oil pump for leakage.
Oil tank
Check the oil tank for leakage or water in
the tank. If water is found in the oil injection
system or if the oil tank needs to be cleaned
have a Yamaha dealer service the water-
craft.

Inspecting the battery
Check the level of the battery electrolyte
and make sure the leads are secure.
WARNING
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg or vegetable oil. Call physi-
cian immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flame, cigarettes, etc., well away.
If using or charging the battery in an
enclosed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHIL-
DREN.
CAUTION:
Be careful not to place the battery on its
side.
Make sure to remove the battery from the
battery compartment when adding bat-
tery electrolyte or charging the battery.
When checking the battery, make sure
the breather hose is connected to the
battery and not obstructed.
