DO NOT continue to de-
press the “Parallel 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 be-
fore departing the dock/mooring. The proper
“warm-up” procedure is as follows:
Check the oil pressure gauges to be
certain each engine has suffi cient oil
pressure. Gasoline engines should
have between 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 respec-
tive engine and contact your Silverton
dealer for further inspection and repair,
if necessary.
Allow the engines to run at the RPM’s
specifi 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 signifi 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
exhaust outlets indicates proper water
circulation in the engine exhaust system.
Water should start coming out of the
•
•
•
exhaust outlet shortly after the engine is
started. If you do not observe any water
coming from the exhaust outlet(s), turn
OFF the respective engine and contact
your Silverton dealer for inspection and
repair, if necessary.
The exhaust system is raw
water cooled. If there is no presence of
water in the exhaust outlet(s), the ex-
haust system may overheat, resulting in
serious damage to the engine(s) and the
exhaust system components.
After both engines have reached their
normal operating temperature, increase
the RPM’s to 2000 and check both volt-
meters to be certain they read between
13 and 14.5 volts. The engine voltmeters
are located on the Helm Gauge Panel
(See Helm Gauge Layout on Page
158, which illustrates the location of the
voltmeters).
If the voltmeter(s) read
above 15 volts, turn OFF the respective
engine(s) as damage to the alternator(s)
may result.
Visually inspect the engine compartment
for fuel, oil and water leaks. If leaks are
observed, attempt to locate the source
and contact your Silverton dealer for
inspection and repair, if necessary.
Visually inspect the exhaust system for
leaks. If any leak is observed, immedi-
ately turn OFF the engines and contact
your Silverton dealer for inspection and
repair, if necessary.
