SYSTEM OPERATIONS-53
If the engine alarm buzzer DOES NOT
turn OFF, turn OFF the engine immedi-
ately if the oil pressure gauge displays
no, or very low, oil pressure. See your
Silverton Dealer for inspection and
repair, if necessary. No, or very low,
oil pressure may cause serious dam-
age to the internal mechanism of your
engine(s).
If the automatic fi re extinguisher indi-
cator light DOES NOT remain illumi-
nated, turn OFF the engine(s) immedi-
ately and follow the proper procedure
to check for
fi re aboard your yacht as
detailed in the Automatic Fire Extin-
guisher System Section of this Owner’s
Manual. A
fi re aboard your yacht may
result in serious personal injury or
death.
If one of the batteries is “dead” or not
suf fi ciently charged to start your engine,
depress the “Parallel Start Switch” simul-
taneously while turning the ignition switch
to START. The parallel start switch draws
power from both batteries during the start-
ing procedure and it is located on the helm
switch panel. Refer to the Electrical pages
of this section of your Owner’s Manual
for a location of the Switch. Release both
switches immediately after the engine
starts.
DO NOT continue to depress the “Par-
allel Start Switch” after the engine has
started. Damage to the alternator(s)
may result.
After you have started both engines and
determined they are running properly, the
“warm-up” procedure should be followed
before departing the dock/mooring. The
proper “warm-up” procedure is as follows:
Check the oil pressure gauges to be
certain each engine has suf fi cient oil pres-
sure. Gasoline engines should have be-
tween 30 and 50 psi (pounds per square
inch) and diesel engines should have
between 35 and 70 psi. If the oil pressure
is lower than the normal operating range,
turn OFF the respective engine and con-
tact your Silverton Dealer for further in-
spection and repair, if necessary.
Allow the engines to run at the RPM’s
speci fi ed in the Engine Manual until they
reach the proper operating temperature.
Normal operating temperature for gaso-
line engines is 140° F with a raw water
cooling system and 170° F with a fresh
water cooling system. The normal oper-
ating temperature for diesel engines is
between 170° F and 190° F. If the engine
temperature rises signi
fi cantly above the
normal operating range (10° F), turn OFF
the respective engine and contact your
Silverton Dealer for inspection and repair,
if necessary.
Check the exhaust outlets for the pres-
ence of water. Water coming from the ex-
