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.
@
NOTE:@ 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
EJU01878
Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment
remove the rear and front seats. (See pages
2-5 and 2-6 for seat removal and installation
procedures.) Allow the engine compartment
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.
EJU20570
Hull and deck
Check the hull and deck for cracks or
other damage. If any damage is found, have
a Yamaha dealer repair the watercraft.
EJU01802
Fuel level
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-11 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 the rear and front seats. (See
pages 2-5 and 2-6 for seat removal and
installation procedures.)
3. Check the fuel level in the tank and
replenish if necessary. (See page 3-4 for
filling instructions.)

Engine oil level
Check the engine oil level before each
use.
CAUTION:@ When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.
When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 4-1 for proce-
dures on supplying water.)
Make sure that the engine has enough
oil but do not overfill it. If there is too
little oil, the engine can be damaged. If
there is too much oil, the air filter can
become saturated with oil, perma-
nently damaging the filter and reduc-
ing engine performance. Follow the
checking procedure carefully.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause seri-
ous engine damage.
@
Checking the engine oil level:
1. Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
2. Run the engine at trolling speed for 6
minutes or more, and then stop the
engine.
NOTE:@ If the ambient temperature is 20 °C (68 °F)
or less, warm up the engine for an additional
5 minutes.
@
3. Remove the rear and front seats. (See
pages 2-5 and 2-6 for seat removal and
installation procedures.)

Lubrication
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
1. Remove the rear and front seats. (See
pages 2-5 to 2-6 for seat removal and
installation procedures.)
2. Remove the air filter case cover
screws1, slide the locks 2 open, and
then remove the case cover.
3. Remove the air filter case cover and air
filter element.
4. Spray a rust inhibitor into each intake
opening 3 for 3 seconds.
5. Install the air filter element and air filter
case cover.
6. Start the engine in a well-ventilated area
and let it run at idle for 15 seconds.
CAUTION:@ Do not run the engine for more than
15 seconds. The engine could overheat.
@
7. Lubricate all cables such as the throttle
and steering cables.
NOTE:@ Use a suitable marine grease applicator to
pressure lubricate the cables and purge out
any moisture between the inner and outer
cables.
@
8. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-18.

Checking the air filter element
The air filter element should be checked
every 12 months or every 100 hours of oper-
ation.
To check the air filter:
1. Remove the rear and front seats. (See
pages 2-5 and 2-6 for seat removal and
installation procedures.)
2. Remove the air filter case cover
screws1, slide the locks 2 open, and
then remove the case cover.
3. Remove the air filter element and check
it for dirt and oil. Replace the air filter ele-
ment if there is any oil buildup, or every
2 years or every 200 hours of operation.
4. Install the air filter element in the air filter
case, and then install the case cover.
CAUTION:@ Make sure that the air filter element is
installed in the filter case properly.
Do not start the engine with the air fil-
ter element removed, otherwise the
pistons and cylinders could be dam-
aged.
If cleaning the air filter element, use
cold or lukewarm water and let it air
dry completely. Do not use detergent
or solvent to clean the air filter ele-
ment, or dry it with heat or com-
pressed air, otherwise it could be
damaged.
