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
OMSB

CARVER

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
B4 OMSB
CARVER

Ignition Switch(s) and aI/ instruments, controls, etc.
should beprotected from the weatherwhen not in use.
Carver offers appropriate weather covers for each
model. Excessive exposure can lead to gauge and
Ignition Switch difficulties.
Electronic gauges are affected by static electricity that
builds-up on the glass face. Periodic washing of the
gauge face with warm water and mild liquid detergent
will help eliminate the static electricity problem and
improve gauge accuracy.

CONTROL SYSTEMS
C-1 GENERAL
The remote control systems which permit operation of
the engine's throttle and shift mechanisms consist of
three major components, the control, the throttle and
the shiftcables. The various types of controls and their
operation are discussed in section C-2.
The cables are all push-pull type. Two cables are
required. One connects the remote throttle control to
the carburetor and the other connects the remote shift
control to the outdrive or transmission shift linkage.
C - 2 CONTROL OPERATION
The various mounting locations, number of control
stations with whichtheboat is equipped and thetype of
engineinstalledareall important
in determiningthetype
of control to be used. Each control is equipped with a
means of permitting the engine to be operated at high
speed while in neutral for cold starting and warm-up
purposes.

During the general operation of adual engine boat,
it is
adventageous both engines should be operated at the
same rpm. This reduces noise, and vibration and can
increase engine efficiency. Setting the throttles so the
engines are running the same rpm (synchronized) can
be done by the engine sounds
or you can purchase an
instrument (Engine Synchronizer) as described in
Section
B. Attempting to synchronize the engines
solely by using tachometer readings or control lever
plac~ment generally will not work. When the engines
are In proper synchronization, the throttle levers may
not necessarily be even.

turer. Detailsoncontrol operation and maintenanceare

C - 3 NEUTRAL SAFETY SWITCH
Everycontrol system has a neutral safety switch incor-
porated into it. This device prohibits the engine from
being started while the shift lever is in position other
than the neutral position.

DUAL STATION CONTROLS
Boats equippedwith adualstationcontrol systemutilize
"station-to-station" cables to interconnect the upper
and the lower stations. Due to the added machinery, a
dualstationcontrolsystem
is inherentlystifferoperating
than a single station. This
is usually more noticeable at
the upper station.
C - 5 CONTROL SYSTEM MAINTENANCE
Periodic inspections of the control(s), cables, and all
connections should be made. Signs of rust, corrosion,
wear, cable jacket cracks orotherdeterioration
requ ire
immediate system servicing. If your unit
is equipped
with electric shift, inspect the shift wire for fraying,
embrittlement and insulation cracks. Repair
all noted
deficiencies. >
Generally, periodic lubrication of all moving parts and
connections with a light, waterproof grease
is in order.
Cables can be lubricated by positioning them to their
fullest extension and applying light grease
to the inner
cable near the jacket. Working the cables back and
forth will distribute the grease
in the inner cable. Re-
apply the grease if necessary.
Lubrication should be performed as often
as necessary
to keep the system operating smoothly. Cable manu-
facturers such asTeleflex and Morseoftenoffer special
tools to make cable lubrication easier.
Cable and control adjustments may become neces-
sary. Adjustment screws
in the control, on the cables
and in the linkage are provided.

STEERING SYSTEMS
0-1 GENERAL
A. Mechanical Steering
Most single station Carver boats use a rack and pinion
type mechanical steering system.
In this system, a
pinion gear in the steering helm drives a gear rack
attached tothe helm end ofthesteeringcable. A rotary
rack is sometimes used. Though the appearance
is
different, the concept is the same. The steering cable
is
of the push-pull type. As the wheel turns, the pinion
drivestherackwhich pushesorpullsthesteering cable.
The steering cable on a stern drive model connects to
theoutdrive steering linkage,
orthe power steering unit
if so equipped.
B. Hydraulic Steering
MostdualstationCarvermodelsusehydraulicsteering.
The Hydraulic Steering System consists ofthree major
components: the helm assembly, a pressurized reser-
voir, and the hydraulic cylinder. The helm assembly
acts as a pump to move the oil through the system. In
many aspects this type of steering is similar to the
mechanical system. Instead of activating a cable,
turning ofthe helm causes fluid in the hydraulic hoses
toflow and activate the hydraulic cylinder causing the
rudders
or outdrive to turn.
As the wheel is rotated, a slight clicking sound may be
noted. Thisclicking sou
nd is theopening andclosingof
the valves
in the helm unit and is normal.
As the steering wheel is turned, the waterflow past the
rudders,
or outdrive, places a load on the steering
system. The effort required to turn the steering wheel
remains constant regardless of speed oroutdrive posi-
tion. This
is an advantage when the boat is "onplane".
The lack of steering effort can
be a disadvantage at
lowerspeedsbecausetheeffort
is notreducedtowhere
it can turn lock-to-Iock easily.
The torque tab, on stern drive models with hydraulic
steering, must be properly adjusted; see section D-3.
Though the helmsman may not feel propellertorque on
thewheel, an improperlyadjustedtorquetabcan cause
steering difficulties.
For additional information, see the Steering System
Manufacturer's literature that is included with this
manual.
0-2 'OUTDRIVE POSITION INDICATOR
Some Morse helm assemblies are equipped with a
rudder position indicator. This device indicates the
location ofthe stern drive relative to the straight ahead
position. The position indicatoroperates mechanically.
Proper adjustment and free operation are essential
if
proper rudder position indications are to be provided.
Periodiclubricationofall moving parts withintherudder
position indicator is necessary
to maintain smooth
operation.
o-3 PROPELLER TORQUE
Propeller rotation by a single engine installation will
exert a directional force on the steering system. This
action can cause steering to be harder
in one direction
than the other; this is referred to as propeller torque.
Stern driveunits areequipped with an adjustabletab on
the drive unit to compensate for porpeller torque. This
. tab is used to attain a neutral steering condition
at
normal operating speed. When this condition is at-
tained, equal force will be required to turn the steering
wheel to both port and starboard. See the Engine
Owners Manual for more data.
Propellertorquecan also prevent the boat from follow-
ing a straight line, orto wander when operated at very
low speed. This condition is normal and can be cor-
rected by increasing engine rpm. Wind, watercurrents
and play at steering conditions can cause equivalent
effects.
0-4 POWER STEERING
Boats equippedwith MerCruisersterndrives are, orcan
be, equipped with MerCruiserpowersteering. This
is a
"power assist" system and can greatly reduce steering
efforts. However, this system is not a full power
steering system as used in automobiles, somesteering
tension remains
in the system.
Upon commissioning the boat, the system must be
purged of air. Should steering difficulty increase with

time, additionalbleedingofthesystem maybe required.
See a dealer; adjustments on a power steering unit
must be performed by a qualified service technician.
Proper power steering fluid level must be maintained.
See the information provided by the power steering
manufacturer for additional information.
D - 5 POWER STEERING MAINTENANCE
Make a periodic inspection of all steering cables, link-
age and helm assemblies. Immediatelycorrect signsof
corrosion, cracking, loosening
of fastenings, excessive
wear, or deterioration. Failure to
do so could lead to
steering system failure and loss of control.
Adjustthe helm andcable assemblyso thatthe system
is centered with the rudders or outdrive in the straight
aheadposition. The steeringwheelshouldbeabletobe
rotated an equal numberofturns to port and starboard
from the straight ahead position. If adjustment be-
comes necessary, see your Carver dealer.
All cables, helm assemblies, and steering connections
shouldbe periodically lubricatedwith alight, waterproof
grease. See the manufacturers information provided
with this manual.
Hydraulic steering systems must have all air purged
from system periodically. Some hydraulic steering
systems must be pressurized to achieve optimum
operation. These systems usually require 20-30 psi
pressure. Review the information provide(j
by the
hydraulic steering manufacturer for proper system
specificationsanddetailsregarding systemserviceand
maintenance.

ELECTRICAL SYSTEMS
E-1 GENERAL
All electrical equipment on Carver boats operates on
either 12 volt
DC or 120 volt (220 volts on 50 Hertz
models) AC electrical power. An understanding ofthe
systems and their operation can be easily gained
through a study of the major components which com-
prisethe electrical circuitry. Section Edescribes the 12
volt system and the related operation. Also
in Section E
is a description of the 120 (220) volt system.

Single Battery Systems
A1 Installation
A single 12 volt DC battery is standard equipment on
certain models. A Battery Selector Switch (see the
Locator Drawing
in Section 0 for the exact location of
the Battery SelectorSwitch) is provided on models with
2 batteries.
Connect the battery
in the following manner:
1. Connect the red battery cable from the Battery
Selector Switch to the positive (+) terminal of the
battery.
2. Connect the black cable from the engine to the
negative (-) battery terminal.
3. Also connect the black lead from the power trim
pump, if so equipped, to the negative
(-) battery termi-
nal.
4. Other black leads for 12 voltequipment, such as
those labelled A, A
1, and AD, must also be connected
to the negative (-) battery terminal.
A2
Operation
All factory installed 12 volt equipment, except for the
automatic bilge pumps and
the voltmeter, are con-
nected to and controlled by the BatterySelectorSwitch
or the main circuit protection device (either fuse or
circuit breaker).
The OFF position of the Battery Selector Switch will
completely shut off 12 volt electrical power. The only
exceptions are the voltmeter (described in Section
E)
and automatic bilge pump (described in Section E).
Always turn the Battery Selector Switch to the OFF
position
or place the main circuit breaker in the OFF
position when the boat
is left unattended for an ex-
tended period.
Positioning the Battery Selector Switch to the
#1 posi-
tion will provide power to the 12 volt electrical system.
In single battery installations, the
#2 position of the
Battery Selector Switch is not functional.
INPORTANT: Extendeduse
of 12volt equipment with-
out operating the engine
or charging the battery cou Id
seriously damage the battery.
