OPERATION-3
If one of the batteries is not suffi ciently charged
to start the engine, start the engine with the fully
charged battery fi rst. Start the other engine using
the “Parallel Start” switch, which draws power from
both batteries. Release the parallel start switch im-
mediately after the engine starts.
DO NOT continue to depress the “Parallel Start
Switch” after the engine has started. Damage to
the alternator(s) may result.
Be certain the oil pressure is between 30 and 50 psi
(gasoline engines) or 35 and 70 psi (diesel engines).
If the oil pressure is low, turn OFF the respective
engine immediately.
Allow the engines to operate at the recommended
RPM’s as specifi ed in the Engine Manual until they
reach normal operating temperature. Normal oper-
ating temperature 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 cir-
culation in the exhaust cooling system. Water should
discharge through the exhaust outlets immediately
after the engine starts.
After engines reach their normal operating tem-
perature, 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 techni-
cian 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 condi-
tions. Note any condition 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 Owner’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 genera-
tor, be certain it starts and operates properly. Check
for oil, water, and exhaust system leaks.
Instruments: Be certain that all instruments oper-
ate properly and provide normal readings.
Steering: Check that the steering system is re-
sponsive.
Shift and Throttle Controls: Be certain the shift
and throttle controls operate properly and are in the
proper adjustment.
Transmissions: Check that both transmissions
shift smoothly and positively.
Trim Tabs: Check that the trim tabs operate prop-
erly and are responsive to your use of the controls.
After completing your shakedown cruise, recheck
all fl uid levels. Check all drive belts for the proper
tension. Generally examine all components to be
certain they did not loosen during the cruise. Make
all adjustments as necessary.
