Specifications

underway, or while the generator
is
running, those
awake should be extremely watchful for carbon monox-
ide accumulation in the cabin; especially the sleeping
areas. Open forward facing windows or deck hatches
to provide adequate fresh air ventilation. Keep hatches,
windows, and doorways that face aft or towards the
exhaust discharge closed.
5.
Ventilate your cabin while underway. Open a forward
hatch, porthole, or window to allow
airto
travel through
the cabin. Be very careful of operating the boat with the
cabin door
or
other windows, hatches, or portholes that
face aft, open. The natural vaccuum created during
operation may allow exhaust gasses to be drawn into
the cabin.
6.
Inspect the engines exhaust system frequently.
7.
Have a competent marine engine service technician
inspect the exhaust system whenever the boat
is
in for
service, or
if a change is noted in the sound
of
the
engines.
B-3
STERN DRIVE SYSTEMS
A stern drive or inboard/outboard propulsion system
has a piston engine equipped with special marine
components mounted near the transom and coupled to
an
external outdrive type transmission unit.
Thistype
of system
is
depicted in Figure
B1.
Consult the Engine Owners Manual that has been
provided with this manual for additional information
regarding operation and maintenance.
B - 4 ENGINE COOLING SYSTEMS
All marine engines use surface water as a cooling
medium. The cooling water employed enters the sys-
tem through a water intake and
is
relinquished through
the exhaust manifolding system.
Most stern drive units have the water intake and ex-
haust system incorporated into the outdrive. See the
Engine Owners Manual for additional information.
Installation of "Fresh Water Cooling" provides adequate
engine cooling without exposing the internal engine
cooling system to the detrimental effects of surface
water. Fresh Water Cooling
is
recommended when the
boat will be operated in salt, highly polluted, or silt laden
water. Ask a Carver dealer for recommendations
regarding the necessity of fresh water cooling
in
the
boating area to be used. The Engine Owners Manual
provides additional information regarding service and
maintenance
of
this equipment.
