5.9 Siphon Break
A siphon break prevents seawater entry into the engine
when the engine exhaust manifold outlet is less than
23 cm (9 in.) above waterline. Check the siphon break
at the interval listed in the service schedule. Use the
following procedure and Figure 5-8 to ensure correct
functioning of the siphon break.
Siphon Break Inspection Procedure
1. Stop the generator set.
2. Remove the retaining cap and the reed valve for
inspection. See Figure 5-8.
3. Use a light detergent to clean the reed valve.
4. Check that the reed valve opening is clear.
5. Replace the siphon break if it is cracked or if the
reed valve material has hardened or deteriorated.
6. Install the reed valve downward into the mounting
base.
7. Install the retaining cap and finger-tighten only. Do
not overtighten.
Note:
Consult the installation manual for a complete
explanation
