Engine overheat warning indicator
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the over-
heat warning indicator blinks for 5 seconds,
and then it comes on. The buzzer also
begins to sound intermittently, and then it
sounds continuously. At the same time, the
engine speed reduction control is activated
when the engine runs over 3,000 r/min.
If this occurs, immediately reduce the
engine speed and beach the watercraft, and
check for water discharge at the port (left)
cooling water pilot outlet. If there is no dis-
charge 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 any button on the multifunction meter
to stop the buzzer.
