ENGINES & DRIVE SYSTEMS
B-1 GENERAL
Carver Boat Corporation does not manufacture en-
gines, stern drives orv-drives. These components are
built by manufacturers that are specialists in this field.
Because
of thetechnicaInatureoftheengine and drive
systems, all manufacturers
of these items require that
warranty and service problems be taken directly to
them forresolution. TheService Department ofCarver
Boat Corporation stands ready to assist boat owners
when communicating with the manufacturers of en-
ginesanddrivesystems. Priorto contactingtheCarver
Service Department, thoroughly review any problem
with your Carver dealer.
In compliance with the Federal Safe Boating Act of
1971,all enginemanufacturersrequiretheirproductsto
beregistered. A registration card
is furnished with each
new engine. When selling a Carver boat, the dealer,
along withthe purchaser, shouldcompletethe informa-
tion requested on these cards and return them to the
respective engine manufacturer. (Engine registration
cards can be found in this manual).
Most manufacturers
of the various marine power
components used
in these boats provides an owners
manual with the product. These publications are in-
cluded with this manual. Read the manual(s) carefully
and become completely familiar with the proper care
and operation of the engine and drive system.
B-2 ENGINE EXHAUST
Do Notinhaleexhaustfumes! Exhaustcontainscarbon
monoxide which is colorless and odorless. Carbon
monoxi(:le
is a dangerous gas that is potentially lethal.
The following suggestions can help prevent ex-
haust fumes from entering your boat:
1. Do Not allow the boat to remain stationary with the
engines operating for an extended period of time.
2. Use extreme caution while operating the engines in
confined areas such as enclosed slips, congested
piers, or
in any area where the exhau!)t outlets are
facing
or near a bulkhead orwall structure of any kind.
Operation under such conditions could easily lead to
exhaust gasses (carbon monoxide) entering the boat.
even though you may have all the hatches, windows,
doors and portholes closed.
3. Neveroperatethegeneratorwhiletheboat is moored
against any other boat, dock
or wall structure that is
against or near,the exhaust outlet. Again, operation
under such conditions could easily lead to exhaust
gasses (carbon monoxide) enteringtheboatortheboat
towhich you aremoored, eventhoughyou may haveall
the hatches, windows, doors, and portholes closed,
4. Persons sleeping can be easily overcome bycarbon
monoxide because they are unaware of its presence.
Sleeping while the engines or generator are running
is
llQ1 recommended. Ifpersonsaresleepingaboardwhile

underway, or while the generator is running, those
awakeshould be extremelywatchfulforcarbon monox-
ide accumulation in the cabin; especially the sleeping
areas. Open forward facing windows ordeck hatches
toprovide adequatefresh airventilation. Keep hatches,
windows, and doorways that face aft or towards the
exhaust discharge closed.
5. Ventilateyourcabinwhileunderway. Openaforward
hatch, porthole, orwindow to allow
airto travel through
the cabin. Beverycareful of operatingtheboatwith the
cabindoor
or otherwindows, hatches, orportholes 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 acompetent 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 nearthetransom and coupledto
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-
temthrough awater 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.
Installationof"Fresh WaterCooling"provides adequate
engine cooling without exposing the internal engine
cooling system to the detrimental effects of surface
water. Fresh WaterCooling
is recommended when the
boatwill beoperated in salt, highlypolluted, orsilt 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.

8 - 5 PROPELLERS
Knowledge of the propeller is most easily gained
throughbetterunderstandingoftheterminologyused
to
referto the aspects of propellersize and performance.
A. Diameter
Diameter is twice the distance from the center of the
prop shaft
to the extreme tips of propeller blades.
Increasingordecreasingpropellersizewill haveadirect
bearing on the RPM's an engine will develop. This is
due to the greateramount of propellerblade surface in
contact with the water.
See Figure 82.
8. Pitch
Pitch is a measure of helix angle (orangle of attack) of
the rotating blade. Pitch is easily understood
by imag-
iningthe propellerrotatingthroughasemi-solidsuchas
butter or jello.
The distance the propeller will travel in
one revolution is called "Pitch." Increasing
or decreas-
ing pitch will have a direct bearing on engine RPM's
becauseofthegreaterbite taken
by thebladewith each
rotation. See Figure 82.
C. Prop Slip
When traveling through water a propeller is unable to
get a complete bite because of the fluidity of water.
"Prop Slip" is usually expressed as a percent
of the
computed theoretical speed. Twenty-five to thirty-five
percent prop slip is common for a cruiser type boat
operating at cruising speed.
From the definition given, the deduction can be made
that a propeller,
of a given diameter, with a 10 inch
pitch, rotating at 3600 revolutions per minute, with a
prop slip of 30%, would move the boat at a rate of 24
miles per hour.
Changing eitherdiameter
or pitch will have an effecton
engine speed and prop slip, and in turn, directly effect
the performance of a boat.
The propeller(s) included
witheachCarverboatprovidethebestgeneralperform-
ancebasedondataobtained from on-the-watertesting
of that model. Variations in load, operating conditions,
environment, the individual engine and hull perfor-
mance may necessitate the purchase and use
of an-
other propeller(s).
Underyournormal loadconditionstheengine(s)should
turn within the maximum RPM range when at full
throttle. If the engine(s) exceeds the recommended
RPM an increase in pitch or diameter is required. A
decreasein pitch ordiameterrequired if engine RPM is
too low.
An enginethatis notdevelopingfull power, andtheload
carried in a boat, will directlyeffect performanceofthe
engine. Always be sure
the engine is properly tuned,
and that load conditions are those normally experi-
enced, before changing propellers.
Fora furtherexplanation ofconditions effecting propel-
ler RPM, see a Carver dealer.
8 - 6 ENGINE INSTRUMENTATION
Each pilot station is equipped with a complete set of
engine instruments. These instruments allow the pilot
to constantly monitor
the operational condition of the
engine. Diesel engineboats may use visual indicators
instead
of gauges. Close observation of these instru-
ments could save the engine from damage.

A. Tachometer
The Tachometer indicates the speed of the engine in
revolutions per minute. This speed is not the boat
speed nor necessarily the speed ofthe propeller. The
Tachometer may not registerzero with the Ignition Key
in the OFF position.
B.
Temperature Gauge
Thetemperature gaugemonitorsthecooling system of
the engine. Asudden increase
in thetemperaturecou Id
be a signal of a blocked cooling passage or a water
pump malfunction.
C. Oil Pressure Gauge
The Oil Pressure Gauge provides an indication of the
pressure
in the engine lubrication system. A drop in oil
pressure
is a possible indication ofoil pump or leakage
problems.
D. Voltmeter
Thevoltmetermonitorsthe batterycondition. See Sec-
tion Efor additional information on voltmeteroperation.
E. Fuel Gauge
TheFuel Gaugedisplaysthe level offuel that is present
in the fuel tank(s). See section E for more detailed
information on fuel gauge operation.
F. Power Trim Gauge
Boatsequippedwith MerCruiserStern Drives alsohave
a "Power Trim Gauge." This gauge provides a visual
indication of the inward-outward position
of the
outdrive. Ifthe boat is equipped with a second control
station, an optional PowerTrim Gaugecan
be added to
that station.
G. Engine Alarm Systems
Engine alarm systems are installed on some models
with specific types ofengines. The alarm
is an audible
alarm that is mounted in the helm area;
it is actuated by
engine water temperature and engine oil pressure
senders. Thealarmwillsoundintheeventoflowengine
oil pressure or high engine water temperature.
. The engine alarm will sound during engine startup, or
whenever the Ignition Switch
is positioned to ON and
the engine is not operating. The alarm sounds under
theseconditionsbecauseengineoilpressure
is low;the
alarm willceasetosound as soon as engineoilpressure
rises to the proper level.
IMPORTANT: The engine alarm systems installed
in
these boats monitors only engine water temperature
and engineoilpressure. Always maintain aclosevisual
watch
on the drive(s), transmission(s), engine fluid
levels, bilge water level, etc.
H.
Engine Synchronizer
Most dual engine Carver models can be equipped with
anoptional enginesynchronizer. This instrumentcom-
pares the electrical signals generated by the.engines
and converts those signals to a visual meter indication
of engine speed difference. The meter movement
responds to changes in throttfe position. When the
needle
is centered, theenginesare in proper synchron-
ization. '
I.
Instrument Maintenance
Electrical protection for instruments and ignition cir-
cuitry is provided by a fuse
or cirucit breaker on the
instrument panel.
Periodically, spraythe Ignition Switch(s) with acontact
cleaner/lubricant such as LPS,
CRCor WD40. The
