2008 YAMAHA VX SPORT oil level

Operation
43
NOTE:
If the ambient temperature is 20 °C (68 °F) or
less, warm up the engine for an additional 5
minutes.
(3) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(4) Remove the oil tank filler cap, wipe the
dipstick clean, and then screw the filler
cap into the filler hole completely. Re-
move the filler cap again and check that
the engine oil level is between the mini-
mum level mark and maximum level
mark on the dipstick.
(5) If the engine oil level is below the mini-
mum level mark, add enough oil so that
the oil level is between the minimum and
maximum level marks on the dipstick,and then install the filler cap. If the engine
oil level is significantly above the maxi-
mum level mark, the oil tank is overfilled.
Have a Yamaha dealer remove the ex-
cessive amount of engine oil.EJU32420Water separator
Check the water separator for water. The wa-
ter separator retains any water that may have
entered through the fuel tank breather hose if
the watercraft was capsized. Normally, the
water separator is empty.
If water remains in the water separator, drain
it by removing the drain screw. Place a drain
pan under the water separator to catch the
draining water or use a dry cloth to soak up
any water that could spill into the watercraft. If
any water spills into the watercraft, be sure to
wipe it up with a dry cloth. Also, be sure to in-
stall the drain screw after draining the water
separator.
EJU32460Bilge
Check the bilge for moisture and fuel residue.
CAUTION:
ECJ00370
Excessive water in the bilge can splash
into the engine, which can result in severe
damage.

Operation
WARNING
EWJ00510
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
CAUTION:
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU32781Engine break-in
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
CAUTION:
ECJ00440
Be sure to check the engine oil level be-
fore operating the watercraft for the first
time. (See page 42 for engine oil checking
procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 49 for engine starting
procedures.)
(2) For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5000 r/min. For the 1 hour of
operation after that, keep the engine
speed below 6500 r/min.
(3) Proceed with normal operation.
CAUTION:
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
EJU32811Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
If there are waves, someone should make
sure that the watercraft is not pushed into the
trailer after launching the watercraft.

For VX Deluxe/VX Cruiser:
Use the remote control transmitter to select
the unlock mode. (See page 29 for Yamaha
Security System and low-RPM mode selec-
tion procedures.)
After the watercraft is in the water, start the
engine. Shift into reverse and move the wa-
tercraft back slowly.

For VX:
After the watercraft is in the water, turn it
around so that the bow faces the direction
you wish to go. Start the engine, and then
slowly move away from the launching area.

EJU34451Checking the battery
Check the level of the battery electrolyte and
make sure that the negative (–) and positive
(+) battery leads are tightened securely.
WARNING
EWJ00790
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.

External: Flush with water.
Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten
egg, or vegetable oil. Call a physician im-

Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well ven-
tilated. Always shield your eyes when
