FEATURES AND CONTROLS
RPM Limiter
CAUTION
A clogged intake and/or impeller can cause
engine overheating and/or damage to the jet
pump and impeller parts. Always keep the intake
and/or impeller free of debris and weeds.
Your Polaris watercraft is equipped with a device that
will limit engine revolutions per minute (RPM) if the
engine overheats. This feature is designed to help
prevent engine damage caused by engine overheating.
If the high temperature indicator and warning displays,
stop the engine immediately.

Disable all starting mechanisms and clean the jet pump
and impeller of any weeds and debris that may have
collected during operation. If the cause of overheating
is identified and corrected, normal operation can be
resumed.
If the high temperature indicator and warning did not
display, but the RPM is still limited, check to make
sure the watercraft is not in the reverse mode, because
RPM is limited during reverse operation. See the
troubleshooting section beginning on page 96 for more
information about limit modes.
If RPM continues to be limited, take the watercraft to
an authorized Polaris dealer for service.
