10 Cleaning the strainer
• Close the seacock before removing the lid
of the water strainer.
• Clean the raw water strainer as often as is
necessary, depending on the pollution of
the waterways, but at least once every 6
months. A clogged raw water strainer will
result in excessive temperatures or over-
heating of the engine coolant.

Checking and cleaning the raw water strainer

• Check the sealing between the lid and
housing after cleaning and re-assembling
the strainer. An improperly sealed lid will re-
sult in air sucked in by the sea water pump
which again will result in overheating of the
engine.
Daily, before starting.
