Cleaning seawater filter*
Important
Never open the filter housing
with the seawater valve open to
prevent water from entering.
Observe the safety precautions
beginning on page
performing out any work on the
engine or
compartment.
As the degree of soiling of the seawater
filter is dependent on the water the engine
is operated in, you should check the filter for
soiling each time before starting the engine.
As the cover of the filter housing is transpar-
ent, you do not need to open the cover.

If you determine soiling, proceed as follows:
Close the seawater valve.
Unscrew the screws - see left illustration
- and remove the cover.
Remove the filter element, flush it thor-
oughly with clean water and refit it.
Before screwing on the filter cover, the
sealing ring should be lubricated, e.g. with
silicone oil or Teflon spray.
Check the cover and the seal for proper
seating.
Important
If a cover is not seated correctly,
air can also be aspirated, causing
the engine to overheat.
Open the seawater valve again.
Start the engine and conduct a visual
inspection of the seawater filter* for leaks.
