SYSTEM OPERATIONS-56
Check the oil pressure gauges to be
certain each engine has suffi 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
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 ex-
haust outlets indicates proper water circu-
lation 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 Silver-
ton dealer for inspection and repair.
Visually inspect the engine compart-
ment for fuel, oil and water leaks. If leaks
are found refer to your Fuel Section of
this manual. Also, contact your Silverton
dealer for inspection and repair, if neces-
sary.
Visually inspect the exhaust system for
leaks. If any leak is observed, immediately
turn OFF the engines and contact your
Silverton dealer for inspection and repair,
if necessary.
Check the transmission fl uid level. The
engines should be running at idle speed
and at normal operating temperature. The
transmission fl uid should read FULL on
the “dipstick”. If the fl uid level is low, add
suffi cient transmission fl uid to raise the
level to the FULL mark or slightly lower.
DO NOT overfi ll. If the fl uid level is low,
check the transmission(s) for leaks and
contact your Silverton dealer for repairs if
leaks are noted.
Refer to the ENGINE MANUAL included
with your owner’s packet for addi-
tional technical information concern-
ing maintenance requirements for the
specifi c engines with which your 38C is
equipped.
