Maintenance
Periodic checks and lubrication will keep
your watercraft in the safest and most effi-
cient condition possible. Therefore, make
sure to carry out the periodic maintenance.
Safety is an obligation of the watercraft own-
er. Proper maintenance must be carried out
to keep the exhaust emission and sound lev-
els within the regulated limits. The most im-
portant points of watercraft inspection and
lubrication are explained on the following
pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories
designed 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
repair establishment or individual. War-
ranty repair, however, must be performed
at an authorized Yamaha marine dealer-
ship.
WARNING
EWJ00312
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.

Emergency proceduresEJU34635Cleaning the jet intake and impeller
WARNING
EWJ00783
Before attempting to remove weeds or de-
bris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe in-
jury or death could result from coming in
contact with the rotating parts of the jet
pump.
If weeds or debris gets caught in the jet intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine speed
rises. If this condition is allowed to continue,
the engine will overheat and may seize.
NOTICE: If weeds or debris gets caught in
the jet intake, do not operate the water-
craft above trolling speed until they have
been removed.
[ECJ00654]
If there is any sign that the jet intake or impel-
ler is clogged with weeds or debris, return to
shore and check the intake and impeller. Al-ways stop the engine before beaching the
watercraft.
(1) Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches. Turn the
watercraft on its side as shown.
NOTICE: Always turn the watercraft
over onto its port (left) side. When
turning the watercraft on its side, sup-
port the bow so that the handlebars
are not bent or damaged.
