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-lO.
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 with an API classification of SJ,
SL, or SM. Change the engine oil and filter after
an"
initial
50 hours
of
break-in operation. Thenfolrow the oil change
interval
as
specified in the
MAINTENANCE
SCHEDULE
section of this manual and not be extended if synthetic oils
are used.
An
oil viscosity
of
SAE
15W-40 is recommended for this
engine in all conditions
and
all seasons.
Westerbeke Corporation does not approve or disapprove the
use of synthetic oils.
If
synthetic oils are use, 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 be extended
if
synthetic oils are used.
NOTE:
The infonnation above supersedes all previous
statements regarding synthetic oil.
OVER-FILLING
CAUTION:
The
oil
sump
on
this
generator's
engine
can
unintentionally
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 for 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,
andlor 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°P
(1.12°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.
COOLANT
RECOVERY
TANK
A coolant recovery tank kit
is
supplied with each generator.
The purpose
of
this recovery tank
is
to allow for engine
coolant expansion and contraction during engine operation,
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
pressurelfill cap.
