The model of prefilter can vary according the boat as the
raw water filter is an optional extra not in the scope of
supply of the engine. These instructions are given as an
example only.
Check the raw water filter more regularly than indicated

lot of dirt and/or mud.
TO CLEAN THE FILTER:
1. Stop the engine, remove the key from the panel and
close the sea cock.

Check the condition of the raw water filter. If deposits
have formed, unscrew the cover and remove the seal
plate.

Remove all the contaminants. Rinse the filter and the
housing with fresh water and check the condition of
the seal.
4. Reinstall all the components and open the sea cock.
Start the engine and check for leaks.

through-hull is not clogged by mud or algae.
