recommended RPM’s as specified in the
Engine Manual until they reach normal
operating temperature. Normal operating
temperature for gasoline engines
equipped with a fresh water cooling sys-
tem 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 operat-
ing 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, immedi-
ately turn OFF the respective engine and
contact a competent technician for repair.
✔ Check the transmission fluid level after
the engine is warm. The transmission
should be in neutral and the engines
operating at idle speed. Transmission fluid
should be at or slightly below the FULL
mark on the dipstick. Add transmission
fluid if the level is low, but DO NOT overfill.
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 stan-
dards. Repair any condition 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 valu-
able 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 nor-
mal readings.
❏ Steering: Check that the steering sys-
tem is responsive.
