Care
Of
The
Fuel
Supply
Use
only
clean properly
filtered
fuel!
The clearance of
some
components
in
the
unit's
fuel
system
are
very critical; dirt
particles
which
might
pass
through
the filter
can
damage
these
finely
finished
parts.
It
is
important
to
buy
clean
fuel,
and
keep
it
clean.
The
best
fuel
can
be
rendered
unsatisfactory
by
careless
handling
or improper
storage
facilities.
To
assure that the
fuel
going
into the tank
for
your
engine's
daily
use is clean
and
pure, the
following
practice
is
advisable:
Purchase
a
well-known
brand of
fuel.
Install and regularly service a
good,
Coast
Guard
approved
metal
bowl
type
filter/water separator between
the
fuel
tank
and
the
engine.
ENGINE
OIL
Use a good brand of engine
oil
with
an
API
and
SAE
designations
as
listed in the
SPECIF1CATION
Section
of
this
manual.
Change
the
engine
oil
and
filter
after
an
initial 50
hours
of
engine break-in operation.
Then
follow
the oil
and
filter
change intervals
as
specified in the MAINTENANCE
SCHEDULE in
this
manual.
Westerbeke Corporation
does
not
approve or
disapprove
the
use
of synthetic
oils.
If
synthetic oils are
used,
engine
break-in MUST
be
performed
using
conventional
oil.
Oil
change intervals
must
be
as
listed in the MAINTENANCE
SCHEDULE
section
in this manual and not
to
be
extended
if
synthetic oils
are
used.
NOTE:
The
information
above
supercedes all previous
statements
regarding
synthetic oil
usage.

ENGINE
COOLANT
WESTERBEKE
recommends
a
mixture
of
50%
antifreeze
and
50%
distilled
water.
Distilled
water
is
free
from
the
chemicals
that can corrode internal
engine
surfaces.
The antifreeze performs
double
duty.
It
allows
the
engine
to
run
at
proper
temperatures by transferring
heat
away
from
the
engine
to
the coolant It
also
lubricates
and
prote.cts
the
cooling
circuit
from
rust and
corrosion.
Look
for
a
good
quality
antifreCze
that contains
Supplemental
Cooling
Additives
(SCAs)
that keep
the
antifreeze
chemically
balanced,
crucial
to
long term protection.
The
distilled water and
·antifreeze
should
be
premixed
before
being
poured
into
the
cooling circuit.
NOTE:
Look
for the
new
environmentally-friendly
long
lasting
antifreeze
that
is
now
available.
A
proper
50/50 mixture
as
recommended
will
protect
the
engine
coolant
temperature
to
temperatures
of
-40°F.
COOLANT
RECOVERY
TJ\NK
A
coolant
recovery tank kit is
supplied
with
each

The
pwpose of this
recovery
tank
is
to
allow
for
engine

and
contraction
during
engine.
operation,
without
the
loss
of coolant
and
without
introducing
air
into
the cooling
system.
