NOTE: Pay attention on the white O-ring in order not to lose it.
Cleaning of the water sieve in the Jet Pump:
NOTE: The water sieve protects the exhaust cooling system from sand and other
particles to block the water supply.
A heat sensor will warn you and slow down your personal PWC into the "limp home
mode" of 4000 rpm. This requires regular maintenance.
(There is a second one in the water injection of the exhaust system).
Remove the sieve out of the housing with a tool.
