accumulated oil or dirt that could clog the element and

cause poor performance. See Section 1 for location.

3.6 Exhaust System

Use only

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 line, hose clamps, silencer, and

outlet flapper) for cracks, leaks, and corrosion.

Exhaust System Inspection Points

Check for exhaust leaks and blockages. Check the

silencer and piping condition and check for tight exhaust

system connections.

Check the hoses for softness, cracks, leaks, or dents.

Replace the hoses as needed.

Check for corroded or broken metal parts and replace

them as needed.

Check for loose, corroded, or missing clamps.

Tighten or replace the hose clamps and/or hangers

as needed.

Check that the exhaust outlet is unobstructed.

Visually inspect 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.

Ensure that the carbon monoxide detector is (1) in the

craft, (2) functional, and (3) energized whenever the

generator set operates.
