JET PUMP CLEAN-OUT
PROCEDURE
SEVERE INJURY OR DEATH MAY
RESULT IF YOU IGNORE ANY OF
THE FOLLOWING:
●
Turn off and remove both ignition
keys, remove lanyard, and wait
for all movement to stop before
removing access port caps.
●
Never override interlocks to run
engine with hatch open.
●
The impeller has sharp edges. Be
careful when reaching into jet
pump area.
If weeds or debris get caught in the
intake or impeller, cavitation can occur,
and though the engine speed rises, for-
ward thrust will decrease. If this condi-
tion is allowed to continue, pump
damage can occur and the engines
may overheat and seize. If there is any
sign that the jet intake or impeller is
clogged with weeds or debris, follow
this cleanout procedure.
1) Turn off and remove ignition keys,
remove lanyard, and wait for all
movement to stop.
2) Lift the hatch on the rear platform.
3) Check that the retaining cord is
securely attached to the cap and
retaining strap. Press the release
button and lift the cap up out of the
port. Set the cap where it cannot be
accidentally knocked overboard.
4) Remove any weeds or debris from
the drive shaft, impeller, pump hous-
ing, and steering nozzle. If you can-
not remove the debris, consult your
Yamaha Sport Boat Dealer.
5) To reinstall the access port cap, first
clean off any sand or other foreign
matter from the cap or port surfaces.
Insert the cap so that its projection
faces the bow and lines up with the
slot in the access port wall.

JUMP STARTING
➀
Negative (–) jumper cable
➁
Positive (+) jumper cable
If the boat battery runs down, the
engines can be started in an emer-
gency using a 12-volt battery and
jumper cables.
SEVERE INJURY OR DEATH MAY
RESULT IF YOU IGNORE ANY OF
THE FOLLOWING:
●
If blower will not operate, venti-
late engine compartment by
opening engine compartment
hatch for several minutes before
attempting jump starting.
●
Do not connect the negative (–)
jumper cable to the negative (–)
terminal of the dead battery.
Sparks could ignite battery or
fuel vapors, which could cause
an explosion.
To connect the jumper cables:
1) Connect the positive (+) terminal of
the dead battery to the positive ter-
minal (+)of the booster battery with
the positive jumper cable.
2) Connect one end of the negative (–)
jumper cable to the negative (–) ter-
minal of the booster battery.
3) Connect the other end of the nega-
tive (–) cable to an engine hanger
on either side of the engine oil tank.
Be sure all connections are secure
and correct before attempting to start
the engine. Any wrong connection
may damage the electrical system.
4) Start the engine, then disconnect
the cables by reversing the above
steps.
Do not turn the starter motor for
more than 5 seconds. If the engine
does not start in 5 seconds, release
the starter switch and try again after
15 seconds. Continuous cranking for
more than 5 seconds will discharge
the battery and the engine will not
start. The starter motor may also be
damaged if it is engaged continuous-
ly for more than five seconds.
