Especially for the use of the boat in salt water a
fl
ush system to rinse the open loop cooling circuit is
recommended. Therefore a
fl
ush system has to be
implemented by the boat builder. The following picture
shows an example how to implement this kind of
system.
4.2 Flush
System
The engine has a wet exhaust system. This means sea water is injected into the exhaust out of the open loop
cooling circuit. Due to this water injection the exhaust temperature and also noise is reduced. This water is
pressed out of the exhaust system by the exhaust pressure of the engine. If the engine does not run there is
no mechanism to drain the exhaust system.
Flush procedure:
• Connect the Flush kit
• Start the engine and operate only in idle. Do not accelerate
• Ensure the water supply within 30 seconds
• Flush the open loop cooling circuit for one minute minimum
• Stop water supply
• Stop engine within 30 seconds
•
Remove
the
fl
ush kit
Never
fl
ush without a running engine otherwise there is
a high risk to
fi
ll the engine with water
The engine may only be operated at idle speed for
maximum of 30 seconds without
fl
ush water
