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.
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
monoxide detector(s) for your
safety and the safety of others on
your vessel.
