Drain.
NOTE:
To drain the water, remove the drain plug.

Valve clearance adjustment
The following procedure applies to all of the
valves.
NOTE:
Valve clearance adjustment should be made
on a cold engine, at room temperature.
When the valve clearance is to be measured
or adjusted, the piston must be at top dead
center (TDC) of the compression stroke.
1. Remove:
Ignition coils
Spark plugs
Cylinder head cover
Cylinder head cover gasket
Refer to “CAMSHAFTS” in Chapter 5.
2. Install:
Dial gauge needle
Dial gauge stand 1

(into spark plug hole #1)
Dial gauge 2

NOTE:
The new valve pad number is only an
approximation. The valve clearance must
be measured again and the above steps
should be repeated if the measurement is
still incorrect.
Install the new valve pad 5
and the valve
lifter 6
.
NOTE:
Lubricate the valve pad with molybdenum
disulfide grease.
Lubricate the valve lifter with molybdenum
disulfide oil.
The valve lifter must turn smoothly when
rotated by hand.
Install the valve lifter and the valve pad in
the correct place.
Install the exhaust and intake camshafts,
timing chain, and camshaft caps.
T R..
Camshaft cap bolt:
10 N  m (1.0 kgf  m, 7.2 ft  lb)
NOTE:
Refer to “Camshaft installation — CAM-
SHAFTS” in Chapter 5.
Lubricate the camshafts, camshaft lobes,
and camshaft journals.
Install the exhaust camshaft first.
Align the camshaft marks with the cam-
shaft cap marks.
Turn the crankshaft clockwise several full
turns to seat the parts.
Measure the valve clearance again.
If the valve clearance is still out of specifi-
cation, repeat all of the valve clearance
adjustment steps until the specified clear-
ance is obtained.

Engine oil level check
1. Check:
Engine oil level
Checking steps:
CAUTION:
When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, or obstacles. The
water current or 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.
Make sure that engine has enough oil
but do not overfill. 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 or water does
not enter the oil tank filler hole. Debris
or water in the engine oil can cause
serious engine damage.

Place the watercraft in a horizontal posi-
tion or launch the watercraft.
Remove the seat.
Remove the oil tank filler cap 1
and
check for oil on the dipstick 2
.
If there is no oil on the dipstick, pour
enough oil so that the tip of the dipstick
comes into contact with the oil, and then
install the filler cap.
Start the engine.
CAUTION:
When starting the engine make sure the
dipstick is securely fitted into the oil
tank.
NOTE:
The engine cannot be started if the
Yamaha Security System is in the lock
mode. (Deluxe model only)
For information on the Yamaha Security
System, see the owner’s manual. (Deluxe
model only)
Run the engine at trolling speed for 6
minutes or more, and then turn the
engine off.
CAUTION:
When checking the oil level on land, be
sure to connect a garden hose to the
watercraft for proper water supply.
NOTE:
If the ambient temperature is 20°C (68°F)
or less, warm up the engine for an addi-
tional 5 minutes.
Remove the oil tank filler cap 1
, wipe the
dipstick 2
clean, and then screw the filler
cap into the filler hole completely.

Remove the oil tank filler cap again and
check that the oil level is between the
minimum level mark a
and maximum
level mark b
on the dipstick.
If the engine oil is below the minimum
level mark b
, add sufficient oil of the rec-
ommended type to raise it to the correct
level.
If the engine oil is above the maximum
level mark a
, extract sufficient oil using
an oil changer to lower it to the correct
level.
NOTE:
If the oil temperature is low, the reading on
the dipstick will be low, and if the tempera-
ture is high, the reading on the dipstick will
be high.
Engine oil change — using oil changer
WARNING
Avoid changing the engine oil immediately
after turning the engine off. The oil is hot
and should be handled with care to avoid
burns.
CAUTION:
Do not run the engine with too much or
not enough oil in the oil tank. Oil could
spray out or the engine could be dam-
aged.
Do not run the engine for more than 15
seconds without supplying water, when
checking the oil level on land.
The engine could overheat.
Be sure to change the engine oil after the
first 10 hours of operation, and every 100
hours thereafter or at the start of a new
season, otherwise the engine will wear
quickly.
1. Warm the engine up, and then put the
watercraft in a horizontal position.

2. Remove:
Oil tank filler cap 1

3. Insert the tube of an oil changer into the oil
filler hole.
4. Operate the oil changer to extract the oil.
5. If the oil filter is also to be replaced, per-
form the following procedure.
6. Pour the specified amount of the recom-
mended engine oil into the oil filler hole. Replacing steps:
Place a rag under the oil filter.
Remove the oil filter 1
with an oil filter
wrench.
Oil filter wrench:
YB-01426/90890-01426
Lubricate the O-ring 2
of the new oil filter
with a thin coat of engine oil.
CAUTION:
Make sure the O-ring
2 is positioned
correctly in the groove of the oil filter.
Tighten the new oil filter to specification
with an oil filter wrench.
