8.14.1 Engine exhaust system control
For each engine, you should:
− check the components of the exhaust system (exhaust manifold,
mixing elbow, exhaust line, hose clamps, muffler, etc.) for cracks,
breaks and corrosion.
− check the hoses for softness, cracks, leaks, or dents. Replace them if
necessary.
− check for corroded or broken metal parts. Replace them if necessary.
− 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.
− check for carbon or soot residues in the exhaust components. These
residuals show the presence of leaks that have to be eliminated.

WARNING
Carbon deposits, marine growth, and fouling may affect engine exhaust
operation, causing performance degradation and serious engine
damage. Exhaust outlet blockage, even if partial, may compromise
proper engine operation.
Ensure that the exhaust outlets are free of deposits, growths, and
fouling. Ensure that the parts of the check valves (flappers) move freely
and without any obstruction.
NOTICES
A strong smell and a light smoke from exhaust insulation are normal at
the first start.
S
CAUTION
Carbon Monoxide poisoning hazard - Ensure that the engine exhaust
system operates correctly. Carbon monoxide is extremely toxic.
