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.
Consult the boat builder or dealer for approved detector
location and installation. Inspect the detector before each
generator set use. In addition to routine exhaust system
inspection, test the carbon monoxide detector per the
manufacturer’s instructions and keep the detector operational
at all times.
Exhaust System. Check for exhaust leaks and
blockages. Check the silencer and piping condition and
check for tight exhaust system connections.
Inspect the exhaust system components (exhaust
manifold, mixing elbow, exhaust line, 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.
Note: Never operate the generator set without a
functioning carbon monoxide detector.
