CAUTION:
Be sure to remove the clip from the shut-
off switch, otherwise the engine will
overheat and engine damage may occur.
1. Shut the engine off by removing the clip
from the engine shut-off switch.
2. Swim to the rear of the watercraft. Pull
the watercraft over with left hand on ride
plate while pushing down on the gun-
wale with your right hand/foot.
NOTE:
If the port side of the capsized watercraft is
tilting upward, first tilt the watercraft so the
port side is down by using your weight to
press down on the gunwale.
CAUTION:
Do not turn the watercraft over counter-
clockwise, otherwise water may leak into
the carburetor and engine and cause
damage.
3. Start the engine, and then head for
shore to inspect the engine for water
damage.
CAUTION:
If the watercraft has been capsized for
5 minutes or more, air may have entered
the oil injection system. Leave the engine
off, or operate only at trolling speed, for
10 minutes after the watercraft has been
turned right-side up. This will allow any
air to bleed off.

Adjusting the carburetor
The carburetor is a vital part of the engine
and requires very sophisticated adjustment.
Most adjusting should be left to a Yamaha
dealer who has the professional knowledge
and experience to perform it. However, the
operator may adjust the trolling speed as
part of the usual maintenance routine.
CAUTION:
The carburetor was set at the Yamaha
factory after many tests. If the settings
are disturbed by someone who does not
have the necessary technical knowledge,
poor engine performance and damage
may result.

Adjusting the trolling speed
1. Put the watercraft in the water.
2. Start the engine and warm it up for 1 or
2 minutes. Using a diagnostic tachome-
ter or, if necessary, the tachometer in the
multifunction information center, adjust
the engine speed to specification.
3. Turn the throttle stop screw 1 clockwise
to increase engine speed if necessary.
Turn it counterclockwise to decrease
engine speed if necessary.
Trolling speed: 1,250–1,350 r/min
