Engine Overheat Warning Indicator - Yamaha FX High Output WaveRunner 2004 Owner's/Operator's Manual

EJU20790

Engine overheat warning indicator

This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light and the overheat warning indicator
blink for 5 seconds, and then come on. The
buzzer also begins to sound intermittently,
and then it sounds continuously. At the
same time, the engine speed is limited to
3,000 r/min to help prevent damage.
If this occurs, immediately reduce the
engine speed, beach the watercraft, and
then check for water discharge at the port
(left) cooling water pilot outlet. If there is no
discharge of water, check the intake grate
and impeller for clogging.
WARNING
@
Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:
@
If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.
@
NOTE:
Press the select button 1 on the multifunc-
@
tion meter to stop the buzzer.
