AND
ENGINE
COOLANT
GASOLINE
Use
only unleaded gasoline with
an
octane rating
of
89
or
higher. Higher octane
is
recommended.
The use of lower
octane gasoline
will adversly affect engine performance.
Ethanol blends
must not exceed
E-10.
When
fueling,
follow
U.S.
Coats Guard Regulations. Close all
hatches
and
companionways to prevent
fumes
from
entering
the
vessel.
Ventilate
properly after fueling
and
before starting
the
generator or main engines.
Use
only
clean fresh
fuel!
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.
This filter rating must be
10
microns
or
smaller.
ENGINE
OIL
Use a heavy duty engine oil as called for in the
Specifications Section of
this manual. Change the
engine
oil and filter after the initial 50 hours
of
break-in operation. Then follow the oil and filter
change
intervals
as
specified in 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
of
this manual and.not extended
if
synthetic
oils
are
used.
NOTE: The information above supersedes all
previous statements regarding synthetic oil.
OVER·
FILLING
CAUTION:
The oil sump
on
this
generator's
engine
can
unintenUonally
be
over-filled!
After shutdown, the oil in the engines internal pasages
can
linger and take a number
of
hours
to
drain back into the
sump.
Allow at least a few hours
f()r
the oil to settle back
into the
sump
before
checking
the
dipstick reading.
(Re-starting the engine
is not a problem
as
the engine's
internal passages
are
well lubricated).
Over-filling the engine's
sump
will result in erratic operation,
and/or a smokey
oil laden exhaust, hard starting
and
possible
no
start.
ENGINE
COOLANT
Engine
coolant a 50/50 mixture of antifreeze and distilled
water.
This coolant allows the engine
to
run
at
its
proper
temperature by transferring heat from
the
engine
to
the
coolant.
It
also
lubricates and protects
the
cooling system
from
rust
and
corrosion. A 50/50 mixture of antifreeze
and
distilled water will protect
the
engine
to
-34"F (l.l2°C).
PURCHASING
ANTIFREEZE
Rather
than
preparing the mixture,
WESTERBEKE
recommends
buying the premixed antifreeze
so
that
when
adding coolant; the mixture will always be
correct.
There
are
two
common
types
of antifreeze, Ethylene
Glycol
(green) and Propylene Glycol (red/purple). Either can
be
used
but
do
not mix
the
two
and
if
changing
from
one
to
another,
flush
the
engine
thoroughly.
COOLANT
RECOVERY
TANK
A,f.Oolant
recovery tank kit is supplied
with
each
generator.
The purpose of
this
recovery tank
is
to
allow for engine
cool~
expansion
and
contraction during engine
()peration,
without the loss of coolant
and
without introducing air
into
the
cooling system.
NOTE:
This
coolant
recovery
tank,
with
its short length
of
hose,
is
best located
at
or
above
the
cooling systems
pressure/jill
cap.
