EXHAUST SYSTEM PRECAUTIONS
Carbon Monoxide
The best protection against carbon monoxide poisoning is a
daily inspection of the complete exhaust system. Check for
leaks around manifolds, gaskets, and welds. Make sure
exhaust lines are not heating surrounding areas excessively.
If excessive heat is present, correct the situation immediately.
If you notice a change in the sound or appearance of the
exhaust system, shut down the unit immediately and have the
system inspected and repaired at once by a qualified
mechanic.
A carbon monoxide warning decal has been provided by
Westerbeke. Display this decal near your engine or generator,
on your cabin bulkhead, or in some other nearby location.
NOTE: It is extremely important that a carbon monoxide
detector be installed in your boat’s living quarters. Make
sure it is manufactured for the marine industry. They are
inexpensive and easily available at your marine supplier.
Raw Water Erosion
When the engine’s raw water is fed into an exhaust system so
that the full stream of this water strikes a surface, erosion
takes place. This erosion may cause premature failures. The
proper design of either a water-jacketed or water-injected
“wet” exhaust system to prevent this problem requires that
the raw water inlet be positioned so that the entering stream
of raw water does not directly strike a surface. In addition,
the velocity of the entering raw water stream should be as
low as possible, which can be achieved by having inlet fit-
tings as big in diameter as possible.
Excessive Weight
Make sure there are no unnecessary objects suspended from
any portion of the exhaust lines. Exhaust risers installed off
the exhaust manifold should not exceed 8 lbs in total weight
when rigidly constructed. Excessive weight could cause
deflection or distortion of the manifold resulting in damage
and/or internal leaks.
Insulation
Inspect insulated portions of the exhaust system to ensure
there is no deterioration of the insulation.
Overcranking
Prolonged cranking intervals without the engine starting can
result in filling the engine-mounted exhaust system with raw
water coolant. This may happen because the raw water pump
is pumping raw water through the raw water cooling system
during cranking. This raw water can enter the engine’s cylin-
ders by the way of the exhaust manifold once the exhaust
system fills. To prevent this from happening, close the raw
water supply through-hull shut-off, drain the exhaust muffler,
and correct the cause for the excessive engine cranking
needed to obtain a start. Engine damage resulting form this
type of raw water entry is not a warrantable issue.

▲ WARNING:
Carbon Monoxide Gas is Deadly!
Carbon monoxide is a dangerous gas that can cause
unconsciousness and is potentially lethal. Some of the
symptoms or signs of carbon monoxide inhalation or poi-
soning are:
• Dizziness • Throbbing in Temples
• Nausea • Muscular Twitching
• Headache • Vomiting
• Weakness and • Inability to Think
• Sleepiness • Coherently
If you experience any of the above symptoms, get out
into fresh air immediately.
