EJU32401Engine oil level
Check the engine oil level before each use.
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ00391

Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.

Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine. NOTICE: When check-
ing the engine oil level on land, supply
water to the cooling water passages.
(See page 62 for procedures on sup-
plying water.)
[ECJ01020]
TIP:
When checking the engine oil level on water,
moor the watercraft so that it will not drift
away.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.

Operation
43
Run the engine an additional 5 minutes if
the ambient temperature is 20 °C (68 °F)
or less.
(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 and maximum level marks 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.
(6) Install the seat.
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.
EJU32462Bilge
Check the bilge for moisture and fuel residue.
NOTICE: Excessive water in the engine
compartment 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.
NOTICE
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU32782Engine break-in
NOTICE
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
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.
TIP:
Be sure to check the engine oil level before
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 48 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.
EJU32812Launching 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 lock and unlock mode se-
lection procedures.)

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.
EJU32852Starting the engine
(1) If the lock mode of the Yamaha Security
System is selected (for VX Deluxe/VX
Cruiser), use the remote control transmit-
ter to select the unlock mode. (See page

EJU34392Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate something about
the condition of the engine. For example, if
one spark plug has a distinctly different color,
the engine could require servicing. Do not at-tempt to diagnose any problems yourself.
Have a Yamaha dealer service the watercraft.
Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon
and other deposits are excessive, replace the
spark plug with the specified plug.
To remove a spark plug:
(1) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(2) Remove the spark plug cap. NOTICE:
Do not use any tools to remove or in-
stall the spark plug cap, otherwise the
ignition coil coupler could be dam-
aged. The spark plug cap may be diffi-
cult to remove because the rubber
seal on the end of the cap fits tightly.
To remove the spark plug cap, simply
twist it back and forth while pulling it
up; to install it, twist it back and forth
while pushing it down.
[ECJ00211]
(3) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plug
or adjust the gap to specification if neces-
sary.
