GENERAL INFORMATION
Important information on the function of your engine.
FUEL Use diesel fuel oil of quality "Autodiesel". Poorer fuel quality
can cause interruptions in operation.
LUBRICATING OIL Use only oil of quality CD (DS) according to the API system.
Volvo Penta oil for diesel engines can be used with advantage
since it meets these quality demands. See under "Technical
Data" concerning the viscosity if any other oil is used.
RUNNING IN A new marine engine must be run-in with due care during the
first 20 hours of operation. If full output is taken out during
this time, it should only be done for short periods.
Oil change. Change the engine oil and oil filter after the engine
has been run for 20 hours. See further under "Checks and Service".
ENGINE SPEED Max speed: MD 11 C, MD 1 7C 41.7 rev/sec (2500 rpm)
For choice of correct propeller, refer to the Volvo Penta propeller diagram. Check the
engine speed with normal load in the boat. In order to utilize the maximum performance
of the engine, an engine speed as high as possible should be chosen but not, however,
higher than 41.7 rev/sec (2500 rpm).
Note: When the boat has been in the water for some time, the speed and max rpm can
drop due to marine growth on the hull. Prevent marine growth by painting the bottom of
the boat with anti-fouling paint. See under "Measures taken when launching".

TECHNICAL DESCRIPTION
MD 11 C and MD 1 7C, are 2 respectively 3 cylinder, 4 stroke marine diesel engines,
with direct injection and sea water cooling.
ENGINE ASSEMBLY
The crank case, cylinders and cylinder heads are made of cast iron. The engines
have replaceable cylinder liners and overhead valves.
LUBRICATION SYSTEM
The lubrication system has a full-flow oil filter which cleans the oil before it reaches
the lubrication points. The oil pump has a relief valve which prevents the oil pressure
from becoming excessive.
ELECTRICAL SYSTEM
The engine has a starter motor and an alternator with a built-in rectifier. Voltage
regulation is done by a transistorized regulator mounted on the alternator. The
alternator can charge two batteries, independent of other, if a charging distributor
(accessory) is fitted to the alternator. A main fuse, which can easily be reconnected,
is fixed to the engine. It protects the electrical system from damage in the event of
overloading. The wiring diagrams for the engine and instrument panel are shown on
page 29.

The fuel system has a feed pump with a fine filter, fuel filter with a fine filter insert,
injection pump and injectors. The feed pump is of the membrane type and has a hand
primer lever. There is a built-in cold start device. On the MD11C it is controlled
manually and on the MD17C it is operated automatically.
COOLING SYSTEM
The engine is cooled by sea water. The cooling system has a sea water pump and a
water distribution housing with a thermostat,
The sea water pump has an impeller made of neoprene rubber, which is driven via a
rubber flange from the camshaft.
The thermostat in the water distribution housing regulates the water flow, so that
water is always flowing in the exhaust manifold and out in the exhaust elbow,
regardless of whether the engine is cold or hot.

ELECTROLYTE LEVEL IN BATTERY
The level should be between 5-10 mm (3/16"-3/8") above the cell plates in the
battery. If necessary top up with distilled water. NOTE. Observe great care when
doing this, as the electrolyte is corrosive, and the gas which is formed is explosive.
BELT TENSION
Correct belt tensioning is necessary for full
alternator output. The belt should be so
tensioned that it can be depressed 5 mm
(3/16") with the thumb midway between the
pulleys.
The belt can be tensioned after slackening
the alternator mounting belts.
A well worn or cracked belt should be
replaced.
SERVICE EVERY 50 HOURS OF OPERATION
OIL CHANGE IN ENGINE
NOTE: Since the printing of the book an
alteration has been made in the method of
changing oil. In the case of the MD11C it has
been indicated that the oil screen is to be
removed. If the oil screen for the MD11C
does not have a Wedged handle it must not
be removed. Remove only the oil dipstick
and push the suction tube through the hole.
This procedure has to be followed also on
earlier engines.
With a new or newly reconditioned engine,
the oil should be changed for the first time
after 20 hours of operation, and thereafter
every 50 hours of operation. Run the engine
warm. Suck up the oil with a pump through the dipstick hole.
- 14 -
CHECKS AND SERVICE
On the MD11C the plug together with the oil
strainer must first be removed. NOTE.
When removing the strainer the gasket
must be checked. Re-tighten well.
Fill oil to correct level. Refer to "Technical
Data" regarding choice of oil.
NOTE. The oil filter should also be changed
at every other oil change.
OIL CHANGE IN REVERSE GEAR
The oil can be drained from the reverse
gear by removing the plug under it, or by
sucking up the oil through the dipstick hole
with the help of an oil scavenging pump.
Fill with oil through the filler hole to the
correct level. NOTE. Do not fill above the
Max mark on the dipstick. Regarding
choice of oil, refer to "Technical Data".
VALVE CLEARANCE
The valve clearance should be checked
and adjusted by an authorized workshop.
Refer to "Valves, Technical Data". When
necessary, check and adjust the
decompression device's action on the
exhaust valve.
- 15 -
CHECKS AND SERVICE
SERVICE EVERY 100 HOURS OF OPERATION
OR AT LEAST ONCE EACH SEASON
OIL FILTER
The oil filter should be replaced for the first time after 20 hours of operation during the
running-in period and subsequently at every other oil change. Unscrew and discard
the oil filter.
Coat the new oil filter's rubber seal with oil.
Check the contact surface on the engine
and screw in the filter by hand until it
touches the contact surface. Turn the filter a
further half turn, not more.
NOTE. Use only genuine oil filters.
Start the engine, run at idling and check that
the oil pressure lamp goes out.
Check oil level and that there are no leaks
from the oil filters contact surface.
CLEANING OF AIR FILTER
The air filter should be removed and
cleaned after every 100 hour operation
period or once per season. Loosen the
clamps with a screwdriver and remove the
filter.
Clean the filter with diesel fuel and blow it
clean with a compressed air gun. Soak
them in thin engine oil.
Let the engine oil drain and refit the filter.

CHECKS AND SERVICE
CHECKING AND REPLACEMENT OF PULLEY BELT
Check the belt carefully, both for wear and
cracks. Any sign of such, then the belt must
be replaced. Loosen the alternator mounting
bolts so that the belt can be removed. Dry
the pulley grooves before fitting the new belt.
Tension the belt so that the belt can only be
pressed down 5 mm (3/16") between the
pulleys. After a few hours running, recheck
belt tensioning and adjust if necessary.
RETIGHTENING CYLINDER HEAD BOLTS
Retighten each bolt with a torque wrench before
starting a new engine or an overhauled engine for
the first time, and after 20 hours of operation. The
valve clearance should always be checked after the
bolts have been retightened. Sequence for
tightening the bolts is shown in the figure opposite.
Torques:
Nos. 1, 2, 3 and 4 are torqued to 11 kpm (79 lbft)
Nos. 5 and 6 are torqued to 4.5 kpm (32 lbft)
CHECKING OF COOLING SYSTEM
The cooling system is working normally when the temp gauge is registering within the
green scale and the alarm (if fitted) is silent. Too high water temperature (red scale,
siren is sounding) can be due to the following: blocked water intake, defective
impeller or the flange in the sea water pump, faulty thermostat or temp sender. Be
observant for water ingress when working with the cooling system.
- 17 -
CHECKS AND SERVICE
Checking and changing of the impeller
The impeller can be damaged by e.g. lack of
water. Remove the cover on the sea water
pump. Draw out the shaft enough so that the
impeller's locking screw can be screwed out.
Holding the shaft, draw off the impeller. If the
impeller is damaged it must be changed.
Lock the impeller on the shaft with the
locking screw.
The flange is defective if the impeller and the
shaft can be rotated. A new flange can be
fitted after the pump has been removed.
Refit the cover with its gasket.
ELECTRICAL SYSTEM
Alternator
The engine is equipped with an
alternator. To ensure that the alternator,
with the builton regulator, functions
without interruptions, the following
important points must be observed:
1. The main switch must never be
switched off until the engine has
stopped.
Otherwise would ruin the charging
regulator
2. The battery connection poles must
never be mixed up. A plus sign and a
minus sign are marked on the
respective poles. The minus pole is
connected greased and well tightened.
- 18 -
CHECKS AND SERVICE
3. Re wiring between the charging circuits may not be carried out while the
engine is running.
Fit a Volvo Penta charging distributor
(accessory) on the alternator when more
than one battery is connected.
4. Observe the following whenever the
engine is started with an auxiliary
battery:
Let the ordinary battery remain
connected up. Connect the auxiliary
battery to the ordinary battery, plus to
plus and minus to minus. When the
engine has started, remove the auxiliary
battery, but do not break the ordinary
battery's wiring circuit.
5. Do not use a rapid charging unit when the alternator is connected to the battery.
6. Disconnect both the battery cables before doing any work on the alternator
equipment.
7. When electrical welding work is done to the engine or installation components,
disconnect the charging regulator cables at the alternator and insulate the cable ends.
8. Check regularly the belt tension and the cable connections.
Changing the fuse
A fusebox is mounted on the cylinder. A fuse breaks the electrical system when
overloaded. Re-connect the electrical system by transferring the cable connection to
the next fuse contact.
Starter motor and alternator
All work connected with the starter motor and alternator should be done by an
authorized service shop.
Inspection and control should be carried out in connection with a general inspection of
the engine.
- 19 -
CHECKS AND SERVICE
BATTERY
Checking the state of the battery charge
The charging of the battery should be checked at least once each season. This is
done by using a hydrometer, which shows the specific gravity of the electrolyte, this
varying with the state of the charge. (see "Technical Data").
FUEL SYSTEM
Observe the greatest cleanliness when handling the fuel system. IMPORTANT: Try to
avoid fuel splash.
Changing fuel filter
The filter element in the fuel filter should be
changed at least once each season.
To do this, remove the filter centre screw
and remove the container with the filter. Try
to avoid fuel splash. Clean the container
and contact surfaces, and fit a new filter
element and its gasket. Pump up the fuel
with the hand primer. If the pump action is
poor; turn the engine so that the cam
driving the pump changes position. Vent the
fuel system. (See page 21).
Extra fuel filter
If an extra fuel filter with water separator is
fitted, check the transparent bowl to see if
there is any water in the fuel. If necessary,
drain the filter via the cock in the bottom of
the bowl. Try to avoid fuel splash. Pump up
the fuel and vent the system. The fuel filter
element should be changed at least once
each season.
- 20 -
CHECKS AND SERVICE
Fuel strainer
The fuel pump on the engine has a built-in
strainer, which can be removed by removing
the pump's cover. The strainer must be
cleaned at least once per season. Always
vent the fuel system. Refer to "Venting of
Fuel System" (page 21). Check
immediately after starting that there is no
fuel leakage.
Injectors
The injectors should be removed once a
season and taken to a diesel shop for
cleaning and checking of the spray pattern,
opening pressure and for leakage. Unscrew
the delivery pipe and return pipe from the
injector. Fit protective caps. Loosen the
injector's retainer and lift out the injector. If
the injector feels stiff due to carbon buildup,
grip it with e.g. polygrip pliers and carefully
rotate it back and forth while levering it up
at the same time (with a screwdriver under
the fork), When fitting, check that the
contact surfaces between the injector and
the copper sleeve are clean. Refit and
tighten the delivery pipe and return pipe on
the injector. Make sure the cones are
properly located. Retighten both the nuts
holding the fork alternatively. For the
correct torque, refer to "Technical Data".
Start engine and check for any leakage. If
the delivery pipe has been completely
removed, vent as set out in point 4, page 2
1, to facilitate starting.
- 21 -
CHECKS AND SERVICE
Venting of the fuel system
To enable the engine to start, the fuel system must be vented after carrying out the
following:
Change of fine filter After cleaning the feed pump strainer In the fuel tank has been
run empty When fitting an injection pump If leakage or work has been carried out on
fuel pipes After long laying up periods
Venting is carried out as follows: (Regarding location, refer to Engine Component
Guide)
Open venting screw on the fuel filter about 4 turns. Be
observant for fuel leakage.
Pump up the fuel by using the hand primer until fuel, free
from air bubbles flows out. Close venting screw. If the pump
action is poor, turn the engine so that the cam driving the
pump changes position.
If the injection pump has been removed, or when first
starting a new engine, the injection pump must be vented.
Open the venting screw on the injection pump about 2
turns. Pump the hand primer until fuel free from air bubbles
flows out. Close the venting screw.

LAYING-UP AND LAUNCHING
SERVICE IN CONNECTION WITH LAYING-UP
AND LAUNCHING THE BOAT
INHIBITING ENGINE AND REVERSE GEAR
IDLE ENGINE FOR BRIEF PERIODS WITH BOAT IN WATER
To prevent the engine from corrosion attacks, it must be run warm at least once every
14 days as long as the boat is in the water. If it is anticipated that the boat will not be
used for more than a month, long-term inhibiting should be carried out.
INHIBITING FOR A LONG PERIOD
An authorized service shop should test the engine and equipment before inhibiting
the engine for a long period according to Inhibiting Schemes I and ll. It is advisable to
test the compression to find out the condition of the engine.
INHIBITING SCHEME
Carried out with boat in water
Run the engine warm
Pump out all the oil from the engine and reverse gear
Use an oil scavenging pump
Change the oil filter. Fill the engine and reverse gear to the
correct level with Volvo Penta diesel engine oil, which also has
rustproof ing properties. The engine is thereafter ready for
operation with this oil for the next season.
For long-term inhibiting, exceeding the normal winter lay-up
period, preservative oil should be used. This should be of the
type Esso Rustban 623, Shell Ensis oil or corresponding oil. In
this case, the oil filter shall not be replaced until launching.
Drain the fuel filter and refit the holder with filter. If an extra fuel
filter with water separator is fitted, drain if there is any water in
the fuel.
- 23 -
LAYING-UP AND LAUNCHING
INHIBITING SCHEME ll
Carried out with the boat on land
Disconnect the fuel pump's flexible suction hose from the fuel
system and insert the free end in a can filled with 1/3 Volvo Penta
diesel engine oil or preservative oil, and 2/3 diesel fuel oil. Vent
the fuel system (see page 21).
NOTE. If the fuel system has an electrically operated fuel pump, it
must be switched off.
Drain the cooling water from the engine and reverse gear (pos 14
and 10, pages 31-32). Check to make sure that the water runs out,
as impurities can block the cock. Then close all cocks and re-fit
the drain, cock in the reverse gear.
Disconnect the reverse gear suction line from the reverse gear.
Connect a hose with an inner diameter of 1/2" and insert the free
hose end into a container with fresh water. Arrange to have water
added to the container. Run the engine at idle for about 5- 10
minutes, so that it is flushed throughout with fresh water. At the
same time the fuel system will be inhibited. Check that nothing is
splashed near the exhaust outlet. Drain all water from the engine
and reverse gear. Then close all drain points.
Mix a rustproofing mixture consisting of 10 1(9 Imp. qts = 10,5 US
qts) and 1 1 (1.8 Imp. qts = 2.1 US qts) rustproofing oil of the
emulsifying type. NOTE: Water first and then the oil.
Use, e.g. Esso Cutwell 40, Shell Donax C or similar. As an
alternative, a freeze-resistant 30 % glycol mixture can be used.
Insert the hose into the rustproofing mixture. Start the engine and
let it run at idle until the mixture is finished. NOTE. The water
Pump must never be allowed to run dry.
Connect the fuel pump's flexible suction hose to the fuel system
pipe.
- 24 -
LAYING-UP AND LAUNCHING
Since the rustproofing mixture does not provide any protection
against freezing, it must be drained from the engine and reverse
gear (pos 14 and 10, pages 31-32). Remove the cover from the
cooling water pump. Check to make sure the impeller is in good
condition. NOTE. Do not pull out the impeller if it is in good
condition.
Remove the injector and hand it in to a diesel shop for cleaning and
checking. Inject Volvo Penta oil into the cylinders. Turn round the
engine several turns with the starter motor or the crank. NOTE.
Prevent oil splash. Re-fit the checked injectors, but without
tightening them altogether. They are to be removed again before
launching.
Clean the outside of engine and reverse gear. Touch in any bare
patches in the paintwork with the original type of paint. Spray the
components of the electrical system, and all the controls with
anti-moisture spray.
Remove the battery. It needs to be charged to prevent it from being
damaged.
SERVICE IN CONNECTION WITH LAUNCHING
If Volvo Penta diesel engine oil has been used, you only need to
check the oil level in the engine and reverse gear.
If preservative oil has been used, both the oil and the filter must be
replaced. See under "Service after every 50 hours of operation".
Screw tight the cover with its gasket on the cooling water pump.
Connect the hose between the cooling water intake and the reverse
gear.
Check that all hose clamps are tightened. Close the drain cocks.
Clean the outside of engine and reverse gear.

CHECKS AND SERVICE
OIL LEVEL IN DRIVE
Check every 14 days that the oil level is
within the dipstick's markings.
The oil dipstick has a bajonet fitting,
therefore it must be turned when lifting
and replacing. Note the sealing ring on
the dipstick. When checking the oil level
the dipstick must be turned to the locked
position.
Oil filling is done through the hole for the
dipstick. NOTE. Do not overfill.
Regarding choice of oil, refer to
"Technical Data" page 37.
CHANGING DRIVE'S OIL
Remove the oil dipstick. Unscrew the
drain plug under the propeller gear
housing and let the oil drain off. Refit the
drain plug together with 0-ring. Fill with oil
through the dipstick's hole. NOTE. Do not
overfill. Regarding choice of oil, refer to
"Technical Data" page 37.
ZINC ANODE
Change the zinc anode if it has corroded
by more than 50 %. Remove the
propeller and spacer ring together with
the deflector and remove the two allen
screws holding the zinc anode. Scrape
the contact surface of the drive and fit a
new zinc anode. Make sure that there is
a good metallic contact between the zinc
anode and the drive. NOTE. The zinc
anode must not be painted.
- 37 -
CHECKS AND SERVICE
COOLING SYSTEM
The cooling water intake for the engine's
cooling is located in the drives' lower gear
housing. Check when the boat is taken up
on land, that the grill and the round hole on
the front of the drive is free from marine
growth. If there is a danger of freezing and
when inhibiting, the cooling water is drained
from the drive and the pump by the cock on
the drive. NOTE. When draining while the
boat is still afloat, the cock must be first
closed. Do not forget to open the cock
before the engine is restarted.
GENERAL MAINTENANCE
While the boat is ashore, check the drive's paintwork and if necessary touch it with
genuine Volvo Penta paint. Paint the drive with anti-fouling paint which does not
contain copper. Check from outside that the rubber membrane over the drive's hull
aperture is in place.
Check from inside that the rubber seal between the bed and the drive is not
damaged. A damaged seal must be replaced.
RUNNING Important!
When charging from engine power to sail the propeller's rotation is stopped by
engaging reverse. During sailing the control shall be in the Neutral or Reverse
position, if a folding propeller is used. The control shall be in the Neutral position if a
fixed propeller is fitted.

Publ, no 3386

Supplement to instruction book
MD5A, MD7A, MD1 1C, MD17C
Folding propellers are being used more and more on sailboats. There are several makes to
choose from for conventional installation.
The most important advantage with a folding propeller is that it gives less current resistance
during sailing but when the engine is running it has a somewhat lower effect especially when
manoeuvering astern.
If the boat is supplied with a folding propeller it is important to know about and observe the
following:
Putting in "FORWARD" should take place during idling. Changing at higher r.p.m. can damage
the propeller because of the great stress resulting when the blades are folded out.
When the boat is to be laid up the propeller should be treated as follows:
Clean the propeller with fresh water, remove the screws for the propeller blades' suspension
pins, take away the pins and the blades. Clean all surfaces and then lubricate all the propeller
parts with grease. Take special care with the bearing surfaces on pins and blades. Protect the
propeller boss.
When launching:
Fit the propeller together, wipe off superfluous grease and check that the blades fold inwards
and outwards easily.
