Engine overheat warning 
system

This model is equipped with an engine

overheat warning system. If the engine
starts to overheat, the engine speed will be
limited to about 3,000 r/min. 

When this occurs, check for water dis-

charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then 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.
