Maintenance and adjustments
Periodic inspection, adjustment, and lubrica-
tion will keep your watercraft in the safest and
most efficient condition possible. Safety is an
obligation of the watercraft owner. Proper
maintenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection, adjustment, and lubri-
cation are explained on the following pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories de-
signed for your watercraft.
Remember, failures that are the result of the
installation of parts or accessories which are
not qualitatively equivalent to genuine
Yamaha parts are not covered by the limited
warranty.
Maintenance, replacement, or repair of the
emission control devices and system may
be performed by any marine SI engine re-
pair establishment or individual. Warranty
repair, however, must be performed at an
authorized Yamaha marine dealership.
WARNING
EWJ00311
Be sure to turn off the engine when you
perform maintenance unless otherwise
specified. If you are not familiar with ma-
chine servicing, this work should be done
by a Yamaha dealer or other qualified me-
chanic.
EJU33811Owner’s/operator’s manual and tool
kit
It is advisable to always carry the owner’s/op-
erator’s manual and tool kit with you whenev-
er you use the watercraft. For your
convenience, a storage compartment is pro-
vided on the watercraft for the manual and
tool kit.To protect these materials from water dam-
age, it would be a good idea to put them in a
waterproof bag.
The service information included in this man-
ual is intended to provide you, the owner, with
the necessary information for completing your
own preventive maintenance and minor re-
pairs. The tools provided in the tool kit are suf-
ficient for this purpose, except that a torque
wrench may also be necessary to tighten nuts
and bolts.

TIP:
If removing the spark plug cap nearest the
stern, remove the plastic tie that is securing
the wiring harness before removing the cap.
(4) 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.
To install a spark plug:
(1) Clean the gasket surface.
(2) Wipe any dirt from the threads of the
spark plug.(3) Install the spark plug, and then tighten it
to the specified torque.
TIP:
If a torque wrench is not available when you
are installing a spark plug, a good estimate of
the correct torque is 1/4 turn to 1/2 turn past
finger tight using the spark plug wrench in-
cluded in the tool kit. Have the spark plug ad-
justed to the correct torque with a torque
wrench as soon as possible.
(4) Wipe off any water on the spark plug or
inside the spark plug cap, and then install
the cap. Push the spark plug cap down
until it is securely installed, and then in-
stall the spark plug cap bolts and tighten
them to the specified torque.
If the spark plug cap nearest the stern
was removed, secure the wiring harness
by installing the plastic tie after installing
the cap.
(5) Install the engine cover and engine cover
screws, and then install the seats.
