EXHAUST
SYSTEM
DESCRIPTION
It
is
important
to
install
a
proper
exhaust
system
to
avoid
engine
flooding.
The
system
must
be
designed
to
prevent
water
from
entering
the
exhaust
line
under
any
sea
conditions
and
at
any
angle
of
the
vessel's
hull.
Exhaust
system
failures
are
not
covered
by
Westerbeke's
warranty.
The
installer
should
have
a
basic
knowledge
of
marine
installation
requirements.
Westerbeke
recommends
installing
an
exhaust
system
having
an
in-line
muffler.
The
in-line
muffler
should
be
located
below
the
engine's
exhaust
elbow.
It
must
accumulate
any
water
that
runs
back
down
the
exhaust
line
after
the
engine
is
shut
down.
Design
the
system
so
there
is
an
adequate
drop
in
the
line
between
the
exhaust
elbow
and
the
through-hull
discharge
end
of
the
line.
The
exhaust
hose
must
be
certified
for
marine
use.
A
CAUTION:
An
exhaust
line
that
is
too
long
and/or
has
a
poor
gradient
can
cause
water
to
retum
back
to
the
engine
when
it is
shut
off.
A
WARNING:
The
exhaust
system
must
be
tight
and
free
of
leaks.
Exhaust
gasses
are
deadly.
Display
the
carbon
Monoxide
waming
decal
near
your
engine,
on
your
cabin
bulkhead,
or
in
50me
other
prominent
location.

INSTALLATION
MANUAL
for
MARINE
ENGINES
and
GENERATORS,
Publication
#
43268.
Westerbeke
presumes
that
the
installer
of
this
marine
diesel
engine
is
familiar
with
the
safeguards
a
water-cooled
marine
exhaust
sys-
tem
will
provide
for
the
engine.
Failure
to
design
and
layout
a
proper
exhaust
system
can
result
in
catastrophic
damage
to
the
diesel
engine,
and
possibly
result
in
the
sinking
of
the
vessel
in
which
the
unit
is
installed.
Siphon-Break
For
installations
where
the
water-injected
exhaust
elbow
is
close
to
or
below
the
vessel's
waterline,
provisions
must
be
made
to
install
a
siphon-break
in
the
raw
water
supply
hose
to
the
exhaust
elbow.
The
siphon-break
provides
an
air
vent
in
the
raw
water
cooling
system
to
prevent
raw
water
from
filling
the
exhaust
sys-
tem
and
the
engine's
cylinder
when
the
engine
is
shut
down.
See
SIPHON-BREAK
in
the
COOUNG
SYSTEM
section
for
more
information.
A
CAUTION:
Fal/ure
to
use
a
siphon-break
when
the
exhaust
elbow
is
located
at
or
below
the
load
waterline
will
result
in
raw
water
damage
to
the
engine
and
possi-
ble
flooding
of
the
boat.
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
the
exhaust
manifold/elbow,
exhaust
hose,
gaskets,
and
welds.
Make
sure
there
are
no
fumes
entering
your
boat
from
a
nearby
vessel.
Make
sure
the
exhaust
lines
are
not
heating
the
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
engine
immedi-
ately
and
have
the
exhaust
system
inspected
and
repaired
at
once
by
a
qualified
mechanic.
A
WARNING:
Exhaust
gasses
contain
carbon
Monoxide,
an
odorless
and
colorless
gas.
carbon
Monoxide
is
pOi5Onous
and
can
cause
unconsciousness
and
death.
Symptoms
of
carbon Monoxide
exposure
can
include:
-
Dizziness
-
Throbbing
In
Temples
-Nausea
-
Muscular
Twitching
-
Headache
-
Weakness
and
Sleepiness
-
Vomiting
-Inability
to

OR
ANYONE
ELSE
EXPERIENCE
ANY
OF
THESE
SYMPTOMS,
BET
OUT
lITO
FRESH
AIR
IMMEDIATELY.
If
the
symptoms
persist,
seek
medical
attention.
Shut
down
the
engine
and
rentilate
the
area
with
clean
air.
Do
not
restart
the
engine
until
it
has
been
inspected
and
repaired.
