OPERATION-4
Allow the engines to operate at the recom-
mended RPM’s as specifi ed in the Engine
Manual until they reach normal operating
temperature. Normal operating tempera-
ture for gasoline engines equipped with a
fresh water cooling system is 170° F and if
equipped with a raw water cooling system,
140° F. Normal operating temperature for
diesel engines is between 170° F and 190°
F.
Check for water discharging from the
exhaust outlets. The presence of water
indicates water circulation in the exhaust
cooling system. Water should discharge
through the exhaust outlets immediately
after the engine starts.
After engines reach their normal operating
temperature, increase the RPM’s to 2000.
Be certain the voltmeters read between 13
and 14.5 volts.
Visually inspect the exhaust system for
leaks. If any leaks are detected, immediately
turn OFF the respective engine, and contact
a competent technician for repair.
Check the transmission fl uid level after the
engine is warm. The transmission should be
in neutral and the engines operating at idle
speed. Transmission fl uid should be at or
slightly below the FULL mark on the dipstick.
Add transmission fl uid if the level is low, but
DO NOT overfi ll. Refer to the Transmission
Owners Manual.
Shakedown Cruise
Silverton recommends a shakedown cruise
after the initial or seasonal startup. This will
test the engines and various systems under
normal operating conditions. Note any con-
dition that does not meet normal operating
performance standards. Repair any condi-
tion noted as soon as possible.
IMPORTANT: Before fueling your yacht, be
certain you have read and have a thorough
understanding of the information contained
in the “Fuel System” Section of this Own-
er’s Manual. It contains valuable information
and cautions for your safety and the safety
of your passengers.
Check the following for proper operation
during your shakedown cruise:
Air Conditioner(s): If your yacht is
equipped with an air conditioning system,
be certain each air conditioner is operating
properly.
Engines: Be certain both engines are
capable of obtaining their maximum RPM
range. Check for fuel, oil and water leaks.
Check the exhaust system for leaks.
Generator: If your yacht is equipped with
a generator, be certain it starts and operates
properly. Check for oil, water and exhaust
system leaks.
Instruments: Be certain that all instru-
ments operate properly and provide normal
readings.
Steering: Check that the steering system
is responsive.
