IMPORTANT INFORMATION
Stop the engine before opening the hatch to the engine compartment. An engine which is in
operation has rotating and moving parts which are dangerous to touch.
Bear in mind the risk of a fire. All engine fuel is inflammable.
The cooling system is filled with liquid and it should be drained when there is risk of frost.
Note that in certain cases a suction action may occur when the seawater system is being
drained. Close all drainage points when the boat is not under constant supervision.
Incorrectly performed drainage can cause the boat to become filled with water and sink.

1. Foreword
1.1 Introduction
This introduction book provides helpful information for running and maintaining your marine diesel
engine.
The contents apply to particular engines specifications. Each engine is supplied from Marine Power
Solutions is in accordance with the published specifications.
Examine your engine and other components to be able to find them in this book. Read this book
carefully before operating the engine. Don’t wait until a problem occurs.
1.2 Safety Notice
The following warning notes will alert you to possible bodily injury dangers and to important
information on safe operation of equipment. Observe them carefully. “Warning” notes alone do not
eliminate the dangers that they signal. Personal close attention of equipment are major accident
prevention measures.
WARNING: You are warned that personal injuries, damage to
Property or malfunction of the engine can result from your not following these instructions.

2. General information
Important information concerning the function to your engine
2.1 Fuel
Users can select the proper grade of fuel according to the local ambient temperature as follows:
ASTM D975No.1-D No.2-D……for USA
EN590:96………………………..for EU
ISO8217DMX……………………international
BS2869-A1 A2……………………for UK
JIS K2204…………………………for JAPAN
Before being filled into the engine fuel tank, the diesel fuel must be settled for a long period (normally at
least 48h). Then draw out the upper part. The fuel should be filtered by silk cloth while filling into the
fuel tank. Also let the fuel settle. It will extend service life of injectors and injection pumps.
2.2 Lubricating Oil
You should use 15W/40 lube oil for every ambient temperature. Filter the oil before filling into the
engine
2.3 Cooling Water
It’s recommended to use soft water for engine cooling system, such as rain water, or city tap water, or
clean river water, also it is necessary to add anti-freeze to the soft water before filling into the engine
when the engine operates in the cold weather. Cooling water containing too much minerals will from
water scale in an engine cooling system, affecting the engine cooling efficiency and giving rise to engine
troubles.
If it’s difficult to start the engine under lower ambient temperature, heat the water to about 80℃before
filling it into the cooling system.
2.4 Running In
A new engine diesel engine requires careful running in during the first 20 working hours. Run the engine
as for normal operations but do not load the engine fully during this period. Unnecessary idling with an
unloaded engine should always be avoided. A greater consumption of lubricating oil during the
running-in period is usual. Check the oil level more often during the running-in period.

2.5 Preparation Before Starting
Before starting engine make sure that:
There is no FUEL LEAKAGE
There is no WATER LEAKAGE
There is no OIL LEAKAGE
There is no SMELL OF LP-GAS in the deep cavities of the boat or elsewhere
The OIL LEVELS are correct
The COOLING WATER LEVEL in the expansion tank for the fresh water system is correct.
The proper NAUTICAL CHARTS are on board for the planed voyage
There is enough FUEL on board for the planed voyage
Make sure when filling your fuel tank that there is no open flame on board. Ventilate the boat and run
the engine room fan (if fitted) for 4 minutes before starting the engine. Do not overfill fuel tank.

4.1.4 Cold start: Turn the starter key to position ON. The lamps of REV meter and oil pressure light up.
4.1.5 Press the test button to make sure that the alarm is working.
4.1.6 Turn the starter key to position 1, the solenoid will release the fuel pump.
4.1.7Turn the starter key to position heater and keep for 3 seconds, turn the key to position start, the
start motor will work, release the key when the engine has started. When the engine is running, the key
should be in position 1. Before restarting the engine, return the key to position OFF.
4.1.8 Immediately after starting the engine, check that the oil pressure lamp and
water temperature lamp and that alarm is not sounding, if the alarm is sounding, stop the engine
immediately and investigate the case.
4.1.9 If the engine temperature or oil pressure lamps light up and alarm sounds, either the engine
temperature is too high or the oil pressure is too low, and you should stop the engine and investigate the
case.

9
4.1.10 The single control lever combines the throttle and gear shift functions.
F= Forward
R= Reverse
N= Neutral
T= Throttle
WARNING! Never change travel direction before the engine has returned to idling speed.
For best results, do not run the engine at maximum revolutions for long periods.
4.1.11 Stop the engine by key switch at once if the alarm sounds and the signal lamps light up.
4.1.12 When under sail, the control lever should be in the neutral position if the propeller is a fixed
propeller. If the propeller is a folding propeller, the control lever should be in the reverse position. Start
the engine and run it for 5 minutes every ten hours when on long-distance cruises.

10
4.1.13 Note: Do not switch off the main switch before the engine has stopped.
4.2 Shutdown Procedure
4.2.1 Before shutting down the engine, it should be allowed to idle for a few minutes, with the control
lever in the neutral position.
4.2.2 Stop the engine by key switch when the engine is idling.
4.2.3 Switch off the main switch. IMPORTANT! The main switch must never be switched off until the
engine has stopped. Close the fuel and cooling water cock during long intervals between using. Before
leaving the boat, check that no leakages have occurred.

11
4.1 Frost Risk
If the engine is fitted with a fresh water cooling system, it should be filled with a 50:50 mixture of
anti-freeze and water, or alternatively drained off.
4.2 Draining off fresh water systems
To drain off the fresh water cooling system, open the cock on the side of the engine block.
4.3 Draining off sea water systems
Unfasten the cover on the sea water pump.
Unfasten the hose on the reverse gear.
Remove the pipe.
Close the cocks and refasten the cover on the sea water pump before leaving the boat.
5Checks and Service
5.1 Check daily before starting
5.1.1 Check oil level
Check the oil level every day before starting the engine, to makes sure that it’s within the dipstick
marking for maximum and minimum levels, and that you have enough oil for the journey you are
planning. Fill up with oil when necessary. See “Technical Data” for type of oil to be used.

12
5.1.2 Check water cooling level (Fresh water systems)
Check every day before starting the engine, you open the cap of filler that the water level can be found
from this filler.
When necessary, fill up with fresh water or corrosion inhibitive anti freeze mixture. When there is a
danger of frost it is important to ensure that the fresh water system is filled with anti freeze. Alternatively,
the system can be drained. For draining the sea water system see under “Shut down Procedure”.
5.2 Check every 14 days
5.2.1 Check oil level in gearbox
Check the oil level is within the dipstick marking for maximum and minimum levels,
Fill up with oil when necessary, but do not exceed the maximum level. See “Technical Data” for type of oil
to be used.
5.2.2 Check the belt tension
The V-belt must be correctly tensioned in order to obtain full alternator output. When it is properly
tensioned, it should be possible to push the belt down about 5 mm midway between the pulleys within
your thumb. To tension the belt, first loosen the mounting nut for the alternator. Worn or cracked belts
should be replaced.
5.2.3 Check electrolyte level in battery
The electrolyte level in the battery should be 5-10mm above the cell plates. Fill up with distilled water
when necessary.
Warning: Exercise great care when filling as the gas formed in the battery is explosive and the acid
caustic.

13
5.3 Service every 50 hours of operation
5.3.1 Change oil filter
Run the engine until it is warm. Pump up the oil through the hole for the dipstick, and then refill with oil
to the correct level. See: “Technical Data” for type of oil to be used.
Note: The oil filter should be changed at the same time as every second change of engine oil.
5.4 Service every 100 hours of operation
5.4.1 Change oil filter
The oil filter should be changed after the first 20 hours of running, and thereafter at every second of
engine oil. Screw off the filter and throw it away. Coat the rubber seal of the new filter with oil.
Check the contact surface on the engine, and then screw the filter on by hand until it is just touching the
contact surface. Tighten the filter another half turn. Do not tighten it any further.
Start the engine, let it idle and check that the oil pressure lamp goes out. Check the oil level, and that
there are no leakage around the filter.
5.4.2 Clean intake silencer
The intake silencer should be cleaned each season. Loosen the intake silencer, wash in diesel oil and rinse
thoroughly, Re-fit the intake silencer.
5.4.3 Change oil in gearbox
The oil in the gearbox should be cleaned after 200 hours or at least once a season. Remove the plug
under the gearbox and allow the oil to run out, then re-insert the plug and fill up with oil. Make sure that
the oil level is between the maximum and minimum levels indicated on the dipstick.
Note: Do not exceed the maximum level. See “technical Data” for type and volume of oil to be used.

14
5.4.4 Check/change the impeller
The impeller may become damages, for example through lack of water in the pump due to blocked intake.
Close the bottom cock. Then remove the pump cover and inspect the impeller. If it has been damaged it
should be replaced. Remove the impeller with a pair of adjustable pliers, and fit a new. Then refit the
pump cover with a new seal. Open the bottom cock again.
Warning: Watch out for water leakage.
5.4.5 Check the valve clearance
Checking and adjusting the valve clearance should only be done by professional. See “Valve” under
“Technical Data”.
5.4.6 Check starter and alternator
Checking and maintenance work on the starter and alternator should only be done by professional.

15
5.4.7 Check cooling system
If the cooling system is functioning normally, the “TEMP” lamp will not be lit up. If the temperature is too
high and the lamp lights up, the cause maybe one of the following:
Blocked water intake
Defective impeller in sea water pump
Defective thermostat or temperature gauge
Warning: Watch out for water leakage whenever you are working on the cooling system
5.4.8 Changing the fuse
The fuse box included in the electrical system is mounted on the electrical unit. The fuse will disconnect
the electricity supply if it is overloaded. You can reconnect the circuit by wiring up to the next terminal.
6Laying up and launching
6.1 Inhibiting
While the boat is in the water but not in use, the engine should be run warm at least once every 14 days.
If the boat is not to be used for over a month at a time, long-term inhibiting should be carried out.
6.2 Long-term inhibiting
You should have the engine and its accessories checked by professional before carrying out long-term
inhibiting, and see that any necessary repairs are carried out at this point.
6.3 Inhibiting schedule (with boat in water)
6.3.1 Allow the engine to idle at high revolutions for a few minutes. Then stop it.
6.3.2 Pump all oil out of the engine using the oil pump and drain off the oil out of the gearbox.
6.3.3 Change the oil filter. Fill the engine and gearbox to the correct level. The engine is then ready
to run on this oil next season. When inhibiting for longer periods than normal laying-up for the
winter, special preservative oil should be used, and the oil filter should not be changed until the boat is
launched again.
6.3.4 Change the fuel filter

16
6.3.5 Clean the filter screen and vent the fuel system
6.3.6 Loosen the venting screw on the fuel filter about 4 turns. Watch out for fuel splashing.
6.3.7 Pump up the fuel using the hand primer until the fuel is flowing out free of air bubbles. Tighten
the venting screw again. The fuel injection pump is vented automatically when the engine is started.
6.4 Inhibiting schedule (with boat on land)
6.4.1 Fresh water cooled engine
If the fresh water system has already been filled with ethylene glycol or similar corrosion inhibitive fluid,
check the anti-freeze. If the system has been filled and then filled with a 50/50 mixture of water and
ethylene glycol.
6.4.2 Sea water system
Prepare a 50/50 mixture of fresh water and anti-freeze glycol or similar corrosion inhibitive fluid, and
insert the hose in it. Arrange for the collection of the fluid when it has run through the engine before you
start. Then start the engine and let it idle until all the mixture has been used up.
Note: The pump must not be allowed to run dry.
6.5 Launch the boat
6.5.1 If the propeller shaft is fitted with a rubber stuffing box, press in grease before launching.
6.5.2 The stuffing box should be vented after launching.
Warning: The rubber stuffing box must be replaced after 500 hours or 5 years.
7Tracking faults
7.1 Engine doesn’t start
If the start motor does not turn over, check whether the battery is flat. Use a hydrometer to measure the
specific gravity of the electrolyte. Check that the cables for the battery and starter motor are properly
connected. If the battery is sufficiently charged and you hear a clicking noise from the starter solenoid
when the starter key is turned, the start motor itself maybe defective. If you cannot hear this clicking
noise then there maybe a defect in the solenoid, the key switch or the wiring for them.
7.2 Engine does not start, or stalls
If the start motor does turn over, but the engine either will not start, or keeps stalling, check that you
have fuel in the fuel tank and that the fuel cock is open. If the engine is fitted with an extra fuel filter,
there should be fuel visible in the glass or metal optic.

17
Check that fuel is reaching the injectors by unscrewing the pressure pipe on the injector, and then turn
the engine over using the starter motor. If no fuel appears it may mean that the filter is blocked, the fuel
pump is defective, or that there is air in the system. Change all the filters and vent the system. If not fuel
appears after this, either the feed pump or the injector pump maybe defective.
If fuel does come out of pressure pipe when you carryout this test, it may mean that one of the injectors
is defective. Change the injectors and try to start the engine again. If the engine still will not start the fault
is probably in the injector pump. You should take it to a professional. Check the position of the stop cable.
7.3 Uneven running or excessive vibration
Most interferences in engine running are caused by defects in the fuel supply system, which in turn are
often the result of water, air or impurities getting into the fuel. You should therefore change all the filters
and vent the system, and perhaps change the injectors. Check that all fuel pipes are properly connected.
Rather more infrequently, it may be that the trouble is caused by loss of compression in one or more of
the cylinders. Compression should be checked by professional.
7.4 Engine over heats
If the engine is overheating, check to see if:
The impeller is defective
The cooling water intake or jackets are blocked. (If yes, dismantle and clear them)
7.5 Engine does not attain full revolutions
If the engine starts properly and runs smoothly, but does not reach the same revolutions as previously,
this does not necessarily indicate a defect in the engine, but may mean that there is fouling on the
bottom of the boat, or that it is over loaded. It is also possible that the propeller maybe defective. If all
these causes can be eliminated, there may have been a loss of compression in one or more of the
cylinders. Compression losing should be checked by professional.
7.6 Aligning engine and gearbox
Once a season or after launching, the alignment of the engine with the propeller shaft should be check
and if necessary adjusted. To do this:
Unfasten the screw union for the propeller shaft flange. Using a 0.10mm thickness gauge, check the that
there is not enough room to insert it between the reverse gear and propeller shaft flange any point when
the propeller shaft is pushed forwards. Turn the shaft through 90, 180 and 270 when carrying out this test.
If the gap is more than 0.10 mm the alignment should be adjusted. If a non-adjustable rubber suspension
is fitted, the thickness of the padding should be adjusted.
