6.4 Siphon Break
A siphon break prevents seawater entry into the
generator set’s engine when the engine exhaust
manifold outlet is less than 230 mm (9 in.) above the
waterline of a fully loaded, docked or stationary craft.
The siphon break may malfunction when the generator
set operates while the craft is in contaminated waters or
saltwater. Use the following procedure to inspect the
siphon break at the intervals listed in the service
schedule.
Siphon Break Inspection
1. Stop the generator set.
2. Remove the retaining cap and remove the reed
valve for inspection. See Figure 6-5.
3. Use a mild detergent to remove residue and
oxidation from the reed valve.
4. Clear blockages from the reed valve opening.
5. Replace the siphon break if the reed valve is
cracked or if the reed valve material has hardened
or deteriorated.
6. Install the reed valve into the mounting base with
the valve downward. See Figure 6-5, item 3.
7. Install and only finger tighten the retaining cap. Do
not overtighten it.
