Cleaning the strainer

Close the sea cock 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.
Check the sealing between the lid and
housing after cleaning and re-assembling
the strainer. An improperly sealed lid will
result in air sucked in by the sea water
pump which again will result in overheat-
ing of the engine.
