Thermostat Pop Off Assembly
If low end performance of the watercraft begins to deteriorate, and the jet pump in-
take area is free of debris and weeds; or if the overheat alarm sounds and/or the
LED is flashing "hol' on the MFD, the thermostat popoff assembly should be
checked for debris and cleaned out. Also inspect the thermostat pop off assembly
if the watercraft has been stored for more than 30 days or has been used in salt
water. To do this, use the 311 6" (.5 cm) Allen wrench in the tool kit and a flat screw-
driver.
Sand buildup is possible if you beach your craft. This must be cleaned and flushed
to avoid engine damage.
