Section 4 Exhaust System
4.1 Exhaust System Inspection
Carbon monoxide.
Can cause severe nausea,
fainting, or death.
The exhaust system must be
leakproof and routinely inspected.
WARNING
Inspecting the exhaust system. Carbon monoxide can
cause severe nausea, fainting, or death. For the safety of
the craft’s occupants, install a carbon monoxide detector.
Never operate the generator set without a functioning carbon
monoxide detector. Inspect the detector before each
generator set use.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (- ) lead first
when disconnecting the battery.
Reconnect the negative (- ) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (- ) lead first. Reconnect the negative
(- ) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
1. Press the generator set OFF/RESET button to shut
down the generator set.
2. Disconnect the power to the battery charger, if
equipped.
3. Disconnect the generator set engine starting
battery, negative (- ) lead first.
At the interval specified in the service schedule, inspect
the exhaust system components (exhaust manifold,
mixing elbow, exhaust hose, hose clamps, silencer, and
outlet flapper) for cracks, leaks, and corrosion.
Ensure that the carbon monoxide detector(s) is (1) in the
craft, (2) functional, and (3) energized whenever the
generator set operates.
For your safety: Never operate the generator set
without a functioning carbon
monoxide detector(s) for your
safety and the safety of others on
your vessel.
Exhaust System Inspection Points
Check for exhaust leaks and blockages. Check the
silencer and piping condition and check for tight exhaust
system connections.
D Check the hoses for softness, cracks, leaks, or dents.
Replace the hoses as needed.
D Check for corroded or broken metal parts and replace
them as needed.
D Check f or loose, corroded, or missing clamps.
Tighten or replace the hose clamps and/or hangers
as needed.
D Check that the exhaust outlet is unobstructed.
D Visually inspect the exhaust system for exhaust leaks
(blowby). Check for carbon or soot residue on
exhaust components. Carbon and soot residue
indicates an exhaust leak. Seal leaks as needed.
4. Check that the generator set is OFF.
5. Reconnect the generator set engine starting
battery, negative (- ) lead last.
6. Reconnect the power to the battery charger, if
equipped.
