Safety Information
Daily Checks
Make a habit of giving the engine and engine bay a visual check before driving (before starting the engine) and after operation (when you have stopped the engine). This will help you to quickly discover whether other abnormal event has occurred, or is about to occur.
there is any leakage of fuel, coolant, oil or any
WARNING!
Do not start the engine if there is reason to suspect fuel and/or propane leaks, or if there is explosive material nearby.
Maneuvering
To avoid passengers falling overboard, refrain from extreme and sudden rudder movements and ahead/ astern movements. A rotating propeller can cause severe injuries. Make sure
that there is nobody in the water before engaging ahead/astern drive. Never drive close to bathers or in areas where it can be expected that people are in the water.
Fuel Filling
There is always a risk of fire and explosion during fueling. stopped during fueling. Never overfill the tank. Close the fuel filler cap securely. Only use fuel recommended in the Technical Data, page 130. The wrong grade of fuel can cause serious malfunctions, power loss or stop the engine. In diesel engines, fuel of poor quality can cause damage to the fuel system or cause the engine to over-speed, with risk of personal injury.
Smoking is forbidden and the engine must be
Accidents at Sea
Maritime rescue statistics show that a large number of boat accidents are caused by inadequate engine and boat maintenance and the lack of safety equipment. Make sure that the boat engine is properly maintained by making sure that the recommended service is performed, and that necessary safety equipment is available and functional.
Lanyard Switch
We recommend installing and using a lanyard switch (optional), especially if the boat is capable of high speeds. The lanyard switch stops the engine if the driver looses control of the boat.

Carbon Monoxide Poisoning
P0003073
When the boat moves forward, an area of lower pressure air is formed behind the boat — so-called turbulence. In certain conditions, this turbulence can be powerful enough to draw the exhaust fumes into the cockpit or cabin, creating a risk of carbon monoxide poisoning to people on board. The turbulence problem is most pronounced on tall, broad-beamed boats with a transom stern. But even for other boat types, low-pressure suction can be a problem in certain conditions, such as driving with cockpit awnings rigged. Other factors that can increase load distribution, swell, trim, open hatches and ventilators etc.
the effect of turbulence are wind conditions,
Safety Information
Most modern boats are, however, designed so that the problem of low-pressure suction is very rare. Should turbulence nevertheless occur, hatches or ventilators must not be opened since this might exacerbate the problem. Instead, try to change the speed, trim or load distribution. If possible, take down or open the cockpit awning. Contact your boat dealer for the best solution for your boat.
Remember
The list below includes some tips on what to remember to bring on any boat trip. The list can be extended since the need for safety equipment varies with the boat type and where or how it is used etc. We recommend you ask a regional boat or sea safety organization for more detailed maritime safety information.
Safety Equipment:
life jackets
•
• communication equipment
• emergency rockets
• approved fire extinguisher
• first aid kit
• life buoy
• anchor
• paddle
• flashlights
• Take your chart out and study your planned route. Calculate distance and fuel consumption. Listen to weather reports.
• Tell your friends/relatives about route plans if you undertake a long journey. Remember to notify changed plans or delays.
• Inform everybody aboard about where the safety equipment is located, and how it works. Make sure that there is more than one person aboard who can start and operate the boat safely.
Spare Parts and Tools:
• impeller
• fuel filters
• fuses
• tape
• hose clamps

About this manual
This Operator's Manual has been prepared to give you the greatest possible benefit from your Bukh marine engine. It contains necessary information regarding safe and correct engine operation and maintenance. Read the Operator's Manual carefully and learn to handle the engine, controls and other equipment in a safe manner before you cast off on your maiden voyage.
Always have the Operator's Manual available. Store it safely and do not forget to hand it over to the next owner if you sell your boat.
The Operator’s Manual describes the engine and equipment sold by Bukh. The illustrations in this book may cover several product types, which means that there may be slight differences between the illustrations and the purchased product. This does, however, not affect the validity of the information and/or instructions in the manual. Bukh reserves the right to make alterations to specifications, design features, and illustrations without prior notice.
Warranty
Your new Bukh marine engine is covered by a limited warranty, subject to the conditions compiled in the
6.4-F2 Rev. 30.05.11 General Terms of Sale and Delivery
Read the information carefully, the information can be found on www.bukh.dk
Environmental Care
Bukh has special responsibility as an engine manufacturer, and for this reason environmental care is a natural cornerstone of our product development. Bukh currently has a broad engine program in which great advances have been made in reducing exhaust emissions, fuel consumption and engine noise etc. We hope that you will be keen to preserve these qualities. Always follow the directions in the Operator's Manual regarding fuel grades, operation and maintenance to avoid unnecessary environmental impact. Contact your Bukh dealer if you notice any changes such as increased fuel consumption or increased exhaust smoke.
Your New Boat
Carefully read through the instructions and other information that is delivered with the new boat. Learn to handle the engine, controls and other equipment in a safe and proper manner. If this is your first boat or if the boat type is unfamiliar to you, we recommend that you practice maneuvering the boat before casting off on the maiden voyage. Make yourself familiar with the boat's seakeeping and maneuvering qualities at different speeds, sea states and load conditions.
Bear in mind that a person in charge of a boat under way bears the legal responsibility of knowing and following the regulations for passage and safety afloat. Learn which regulations apply to you and your waters by contacting the relevant authorities or maritime safety organization. We recommend that you complete a boat driver’s course.
Remember always to hand in environmentally hazardous waste such as drained oil, coolant, old batteries, etc. for treatment at a recycling facility.
Our united efforts can make a valuable contribution to the environment.

Introduction
Running In
The engine must be run in during the first 10 hours of operation. Do this by using the engine in normal operation, where full load is only applied for short periods of time. Never run the engine at constant speed for any longer periods of time.
Since oil consumption is higher during the running in period, be sure to control the oil level more frequently than normally recommended. Refer to Maintenance, page 87 for more information.
Fuel, Oils and Coolant
Only use the fuels and oils recommended in the Technical Data, page 129, since other grades may cause malfunctions, increased fuel consumption, and possibly shorten the life of the engine. Always change the oil, oil filters, and fuel filter at the specified maintenance intervals. Make sure to always use suitable and correctly mixed coolant. Future warranty claims related to engine and accessories may be denied if an unsuitable coolant has been used, or if the instructions for coolant mixture have not been followed.
Maintenance and replacement parts
Bukh engines are designed for maximum reliability and long life. They are not only built to withstand a demanding environment, but also to have the smallest possible environmental impact. These qualities will be maintained through regular servicing and the use of spare parts with the same quality as Bukh original spare parts. If reliable and purpose- built parts are not used, your safety, health, and the machine's function may be compromised. Bukh has a world-wide network of authorized dealers.
They are Bukh product specialists, and have the accessories, genuine parts, test equipment and special tools needed for high quality service and repair work. Always observe the maintenance intervals in the manual, the complete Service Protocol can be found at volvopenta.com. Remember to note the engine / transmission identification number when you order service and spare parts.
Excessive Strain On a Product and Components
Bukh products and their components are not dimensioned for external loads. Never stand or step onto an engine, transmission or its components. Loads can bring about damage and the malfunction of a product or property.

Power Trim
Your Bukh drive is equipped with a hydraulic trim system, Power Trim, that allows you to adjust the angle of the drive with respect to the transom from the helm station. The angle of the drive effects the boat's passage through the water and other characteristics, e.g. improved acceleration to planing and planing with a lower throttle opening. Trimming can also be used to give a more gentle passage in short seas.
Trim Ranges
To be able to use the information on the trim instrument, it is important to be aware of the three trim ranges and the way they are used.
Trim range
The trim range are used to provide the best comfort when driving – from starting to top speed.
Beach range
The beach range is used for driving at low speed in shallow water or where the depth is unknown. The highest permitted engine speed when in the beach range is 1500 rpm.
IMPORTANT:
Make sure the of the water when operating in the beach range.
Lift range
The lift range is never used when sailing. It lifts the drive to maximum height and is used for e.g. transporting the boat on a trailer. Power Trim has an automatic stop that turns off the power when the end position is reached. The catch is released automatically when the stern drive is trimmed down.
drive's coolant inlet is never trimmed out
WARNING!
The engine must not be run with the drive in the “lift” range.

Power Trim panel
The Power Trim panel is used for both single and twin engine installations. For twin engine installations, the control panel can be used to make individual or simultaneous adjustments to the drives. The drive's angle and position is shown on the Power Trim panel. By trimming out the drive away from the transom the bow will be ”raised” in relation to the horizontal axis and trimming in the drive will ”lower” the bow of the boat.
Trimming out the drive
On the Power Trim panel, press button + to trim the drive out, away from the transom. The bow will be ”raised” in relation to the horizontal axis.

Maneuvering
The correct trim setting provides the best comfort when driving. Every boat has its own unique characteristics and reacts differently to how you trim it. We can therefore only give general advice about how you reach the best trim angle for your boat. It can generally be said that when the boat feels well balanced, is easy to steer and comfortable to drive - than you have found the optimum trim angle. Make a few trips at low speed to experience the effect of Power Trim and the different trim ranges, to see what effect they have on the boat. Note how long it takes for the boat to reach planing speed. Check the tachometer, speed and the response of the boat.
Trim the drive down
The bows are pressed down and the boat accelerates faster. It also provides better driving and steering response at speeds below the planing threshold.
Driving with ”bow down”
The ”bow down” position is normally used during acceleration up to planing speed, at low planing speeds or with a short sea. With full ”bow down”, the boat has a tendency to self-steer. You may have to compensate with the wheel to keep the boat on the right course. In this position, the bow of the boat tries to go deeper in the water. If the boat is driven at high speed or towards high waves, the bow will plough downwards into the water. The boat can start to steer with the bows or yaw suddenly so that passengers may be thrown overboard.
The boat's trim shall always be adjusted to give well balanced steering. Certain combinations of boat, engine and propeller can cause instability and/or self­steering tendencies when the boat is driven at or close to the maximum ”bow up” or ”bow down” positions. The stability and steering characteristics of the boat can also vary depending on the sea conditions. Contact your Bukh dealer to correct these tendencies if your boat shows instability an/or self-steering tendencies.

Instruments and Controls
At planing speed
Trim the drive to the angle that gives the most stable and comfortable feeling. If the boat has a twin installation, the drive can be trimmed to different angles to compensate for side winds and, to a certain degree, uneven load distribution.
Driving with ”bow down”
The ”bow up” position is normally used for driving at cruising speed, in short seas, or at full speed. With
”bow up” the boat can have a tendency to self-steer.
full You may have to compensate with the rudder to keep the boat on the right course. In this position, the bow of the boat tries to lift out of the water. Excessive ”bow up” trim causes propeller cavitation, so that the propeller looses its grip. The engine speed increases without the boat speed increasing, in fact the boat might even sink. Be careful when driving in short seas. Excessive ”bow up” trim may cause the boat to bounce quickly upwards, with the risk of throwing passengers overboard.
In short seas or heavy head seas
Trim the drive down so that the bow drops. This makes for a more comfortable journey.
Driving in Beach range
The beach range is used for driving at reduced speed in shallow water or where the depth is unknown. The highest permitted engine speed when in the Beach range is 1500 rpm.
IMPORTANT:
sure the drive's coolant inlet is never trimmed out
Make of the water when operating in the beach range.

Joystick Driving
NOTICE! Function Joystick Driving only works
together with Bukh autopilot.
The Joystick Driving function allows the joystick to be used during passage to adjust the boat's heading and maneuver the boat in the same way as with the autoplilot and helm steering unit.
Throttle and gear shift controls work in the normal manner.
Learn to maneuver the boat with the joystick in calm, open waters.
Joystick Driving is activated and de-activated by pressing the button on the joystick.
When Joystick Driving is activated, the autopilot is also started. While the boat is under joystick control the autopilot is in standby mode; when the joystick is released to its central position, the autopilot is activated and locks in on the new heading after a few seconds.
Like the autopilot, the helm steering unit is locked when the function is active but it may always be used for e.g. changing course or giving way to an obstacle. Twist the top of the joystick or move it sideways to reengage Joystick Driving.
If the autopilot is put in standby mode manually by means of the STBY button, Joystick Driving is switched off and must be reengaged using the button on the joystick.
Heading adjustments
Twist the top of the joystick to change heading incrementally. A short twist changes the heading by a fixed increment while a twist held firm will change the heading through several increments.
The autopilot shows the heading with a digital value and a indicator in shape of a blue triangle, a yellow arrow shows the new heading that the boat will be set to.
Maneuvering
The joystick can also be used to maneuver the boat in the same manner as with a helm steering unit. Move the joystick sideways to steer the boat in the same direction. When the joystick is released, the autopilot will set a new heading that corresponds to boat heading.
NOTICE! Full joystick movement to one side corresponds to full helm. Maneuvering abeam provides a faster response than adjusting the heading by twisting the top of the joystick.

Autopilot
For information about Autopilot in glass cockpit displays, refer to the Glass Cockpit Manual. Go to Info > Owner’s Manual to see the manual in the display or download the latest manual on www.garmin.com
Bukh Autopilot consists of a compass unit and the Glass Cockpit Display. The autopilot adjusts boat steering to hold the boat on a straight course. Several different steering patterns can be set and the autopilot also permits manual steering.
Read the instructions carefully and learn to maneuver the boat with the aid of the autopilot in calm, open waters.
NOTICE! The helmsman is responsible for piloting the boat in a safe, reliable manner, even when the autopilot is enabled. Avoid navigational hazards and never leave the helm unattended. Always be prepared to quickly take over the helm.
The autopilot is automatically in standby mode when the boat's electrical systems are switched on. The display will show the main menu or the last menu used.
When the autopilot is active, the helm steering unit is locked but may be used for e.g. changing course or giving way to obstacles. If the helm steering unit is used, the autopilot will automatically enter standby mode and must be reactivated again to function.

Bukh Interceptor System
The Bukh interceptor system is a trim system that uses interceptors installed on the transom to act on a boat's running characteristics and provide a safer, more comfortable passage regardless of weather conditions. The IS system affects a boat's running characteristics at speeds of ≈10 knots and above.
Each interceptor has a blade that extends by varying amounts, depending on the preferred effect, and trims the boat in three axes. The IS system is available in two versions, manual and auto. Manual means the helmsman controls the interceptor blades using control buttons. Auto means the system is pre-calibrated and interceptor blade control is completely automatic to provide optimum safety and comfort. For further information refer to Operation, page 53:
A Trimming angle of attack (the angle between the
bow and the surface of the water). Improves the helmsman's visibility to provide safer passage.

Operation
Cruising Speed
For best fuel economy operations at full speed must be avoided. We recommend a cruising speed that is at least 10% below the maximum engine revolutions at top speed (full throttle). Depending on hull type, the choice of propeller, the load and sea state etc., the maximum revolutions at top speed may vary, but they should be within the full throttle range; refer to Technical Data, page 128.
If the engine is unable to reach its maximum throttle range, this may be due to a number of factors mentioned in Fault Handling, page 70. Select a propeller with greater pitch if actual engine revolutions exceed the full throttle range. Contact your Bukh dealer for advice.
Synchronizing Engine Speed
When driving with twin engines, both the operating economy and comfort will be increased when the engines are operating at the same engine speed (rpm). When the synchronization function is activated, the engine speed (rpm) of the starboard engine is automatically adjusted to that of the port engine. The synchronization function is activated automatically if the following conditions are met.
1 The engine speed levers for both engines are in
(approximately) the same position.
2 The engine speed levers are in a forward position.
The synchronizer is disengaged as soon as the conditions are no longer met or if the engines reach maximum throttle.

Operation break with the boat out of water
Where boats are kept laid up on land when not in use, there is a lower level of galvanic corrosion protection due to oxidation on the sacrificial anodes. Before launching the boat the sacrificial anodes on the drive and shield must be cleaned with emery paper to remove any oxidation. If you expect the boat to be unused for two months or more, it must be inhibited, please refer to Storage, page 110.
IMPORTANT:
Use emery paper. Do not use a wire brush or other steel tools when cleaning, as these may damage the galvanic protection.
Laying Up and Launching
IMPORTANT:
If the boat submerges significantly below the static waterline when it is laid up or launched there is a risk of water entering the engine through the exhaust system.

Trailering Your Boat
Check
local legislation in respect of boat transportation by trailer - there are differences in various national trailer regulations.
Boats with stern drives
Trim the stern drive up to its "lift position" (maximum lift) before the boat is pulled onto the trailer for transportation. It is possible to trim the stern drive without starting the engine. When the stern drive has reached the highest lift position an automatic catch switches off the current to the trim pump. The catch is released automatically when the stern drive is trimmed down. Always secure the stern drive in the up position with a trailer kit (accessory) or similar so that it cannot fall onto the trailer during transportation.
WARNING!
The engine must not be run with the drive in the “lift” range.
Boats with reverse gear
Drain the water from the exhaust system to prevent water entering the engine while the boat is being transported by trailer.
Cold Weather Precautions
If the engine bay cannot be kept frost free, the sea water system must be drained and the freshwater system prevent frost bursting; refer to Maintenance, page 97 and Seawater System, Draining, page 99 respectively for more detailed information. Check the charge status of the battery. A poorly­charged battery can freeze and burst.

In Case of Emergency
Despite regular service in accordance with the planned maintenance schedule and perfect operating conditions, faults may occur that must be remedied before the boat can continue its trip. This chapter provides advice on how to remedy a number of conceivable faults. When certain faults occur safety functions engage to protect the engine. The following may occur:
• Engine cannot be started.
• The gear is in neutral and engine speed is limited
• The engine stops
If a fault occurs, confirm any fault alarm and take the necessary measures. Refer to this section and Fault Code Register, page 71.
Running Aground
The automatic kick-up function releases the drive in the event of running aground or colliding with an object in the water. If the function has been triggered and the drive has kicked up, it must be trimmed back to its original position using the control buttons. The kick-up function only protects the drive when travelling forwards. There is no protection for the drive when travelling backwards.
After running aground, check that the drive and propeller are not damaged and that the drive does not vibrate. If there is damage/vibration, the boat should be driven (if possible) slowly to a harbor and lifted out of the water.
Lift the boat ashore. Check the oil level in the drive. If the oil is gray-colored, water has entered and the drive must be inspected by an authorized Bukh workshop. The same applies if there is damage to the drive. Replace the propeller if it is damaged.
To prevent galvanic corrosion, any paintwork damage on the drive and propeller shall be repaired before launching the boat again.
Checking the tie rod
Check the tie rod that holds the drive together if you have run aground. If the tie rod is bent, loose or damaged, it must be checked immediately by an authorized Bukh workshop. Steer the boat to a harbor at low speed.
WARNING!
If the parallel strut (tie bar) shows signs of damage, run at reduced speed to harbor. The parallel strut is a vital safety component, damage may effect steering characteristics. In the worst case steering could be lost altogether. Never align or weld a damaged parallel strut. Please contact your nearest authorized Bukh workshop for assistance.

safely and correctly. Read the instructions
Fire and explosion
Fuel and lubrication oil
All fuel, most lubricants and many chemicals are inflammable. Read and follow the instructions on the packaging.
Hot oil can cause burns. Avoid skin contact with hot oil. Ensure that the lubrication system is not under pressure before commencing work on it. Never start or operate the engine with the oil filler cap removed, oil can spray out.
carrying out work on the fuel system, make sure
When the engine is cold. A fuel spill onto a hot surface or electrical components can cause a fire.
Store fuel soaked rags and other flammable material so that there is no danger of them catching fire. Fuel­soaked rags can self-ignite under certain conditions.
Do not smoke when filling fuel, oil or in proximity of a filling station or in the engine room.
Non-original components
Components used in the fuel and electrical systems on Bukh products are designed and constructed to minimize the risk of fire and explosion.
Using spare parts that comply with the specifications for Bukh original spare parts is recommended to avoid fire and explosion.
Before starting the engine
Reinstall all protective parts removed during service operations before starting the engine. Check that no tools or other items have been left on the engine.
Never start a turbocharged engine without installing the air cleaner (ACL). The rotating compressor in the Turbocharger unit can cause serious personal injury. Foreign objects can also be sucked in and cause mechanical damage to the unit.
Start spray
Never use start spray or similar agents to start an engine equipped with air pre-heating (glow plugs/ starter element). This may cause an explosion in the inlet manifold. Danger of personal injury.
Hot surfaces and fluids
There is always a risk of burns when working with a hot engine. Beware of hot surfaces. For example: the exhaust pipe, turbo unit, oil pan, charge air pipe, starter element, hot coolant and hot oil in oil lines and hoses.

Maintenance
Carbon monoxide poisoning
Only start the engine in a well-ventilated area. If operating the engine in an enclosed space, ensure that there is proper ventilation in order to remove exhaust gases and crankcase ventilation emissions from the working area.
Chemicals
Most chemicals such as anti-freeze, rustproofing agent, inhibiting oil, degreasing agent etc. are hazardous to health. Read and follow the instructions on the packaging.
Some chemicals such as inhibiting oil are inflammable and dangerous if breathed in as well. Ensure good ventilation and use a protective mask when spraying. Read and follow the instructions on the packaging.
Store chemicals and other hazardous materials out of the reach of children. To protect the environment, please dispose of used or leftover chemicals at a properly designated disposal site for destruction.
Cooling system
There is a risk of flooding when working on the seawater system. Turn off the engine and close the
cock (where installed) before starting work on the
sea system.
Electronic Vessel Control (EVC
The boat has a advanced control system. Never cut or modify connectors, wiring or splice of the components.
Installing components that do not comply with the quality for Bukh original spare parts may cause the system to malfunction. We strongly recommend to use Bukh original spare parts.
Electrical system
Cutting off power
Always stop the engine and break the current using the main switches before working on the electrical system. Isolate shore current to the engine block heater, battery charger, or accessories mounted on the engine.
Batteries
The batteries contain an extremely corrosive electrolyte. Protect your skin and clothes when charging or handling batteries. Always use protective goggles and gloves.
If battery electrolyte comes into contact with unprotected skin, wash off immediately using plenty of water and soap. If battery acid comes into contact with the eyes, flush immediately with plenty of water and obtain medical assistance without delay.
Avoid opening the coolant filler cap when the engine is hot. Steam or hot coolant can spray out and cause burns.
If work must be carried out with the engine at operating temperature and the coolant filler cap or a cock open or a coolant hose disconnected, open the coolant filler cap carefully and slowly to release pressure before removing the cap completely. Note that the coolant may still be hot and can cause burns.
Fuel system
Always use protective gloves when tracing leaks. Liquids ejected under pressure can penetrate body tissue and cause serious injury. There is a danger of blood poisoning.
Always cover the generator if it is located under the fuel filter. The generator can be damaged by spilled fuel.
The engine and the area around the engine must be kept clean from fuel to avoid accidents, engine damage and injuries.
The batteries contain and emit oxyhydrogen gas, especially during charging. This gas is easily ignited and highly volatile.
Do not under any circumstances smoke or use naked flame or allow sparks in the vicinity of the batteries or battery compartment.
An incorrect connection of a battery terminal cable or jump-start cable can cause a spark which in its turn can be sufficient to cause an explosion.

Fuel System
Only use the grades of fuel recommended in the fuel specification, refer to Technical Data, page 130. Always observe the greatest cleanliness during refueling and work on the fuel system.
All work on the unit injectors of the engine must be carried out by an authorized Bukh workshop.
WARNING!
Fire hazard. A fuel
spill onto a hot surface or electrical components can cause fire. When carrying out work on the fuel system, make sure the engine is cold.
WARNING!
Store fuel soaked rags and other flammable material so that there is no danger of them catching fire. Fuel soaked rags can ignite spontaneously under certain conditions.

Fuel system, bleeding
The fuel system must be bled after a filter change, if the fuel tank has been run dry and after a long-term stoppage.
IMPORTANT:
Never disconnect the pressure pipe.
1 Connect
Feed the hose to a container to avoid spillage.
2 Open the bleeding nipple and pump fuel with the
hand pump (2) until the fuel is free from bubbles. Close and tighten the bleed nipple.
3 Pump a further 10 times on the hand pump.
Resistance in the hand pump can feel heavy, but this is completely normal and necessary to bleed the system.
4 Remove the hose and fit the protective cap to the
bleed nipple.
a transparent hose to the bleed nipple (1).
Water in Fuel
If the EVC system warns for too much water in the fuel filter, the water separator needs emptying.
IMPORTANT:
Do not continue operating if there is water in the water separator, it can damage the engine.
Draining the fuel filter
1
Stop the engine and turn off the ignition.
2 Remove the connector piece (1) from the
sensor(2).
3 Place a container under the fuel filter and carefully
unscrew the sensor (2). Let the water run out. When diesel runs out, screw in the sensor until you feel slight resistance. Then tighten an additional 1/4 to 1/2 turn.
IMPORTANT:
If the sensor is torqued more than 1/2 turn, the sensor can be damaged.
4
Refit the connecting piece (1).

Freshwater System
The cooling system ensures that the engine operates at the correct temperature. It is a closed system that should always be filled with a coolant mixture.
IMPORTANT:
Coolant of a suitable chemical composition must be used all year round to protect the engine against internal corrosion, cavitation and frost bursting. This even applies when there is no risk for frost damage, to make sure the engine always has a complete corrosion protection.
Therefore, the use of anti-corrosion agents alone, or water alone as a coolant, is not permitted in Bukh engines.
The coolant must be based on Organic Acid Technology (OAT). Using an improper coolant or mixing with another coolant will rapidly reduce the performance and lifetime of the engine. Material incompatibility can lead to leakages, which - in the worst case - can cause engine breakdown.
Bukh strongly recommend the use of our own coolants, ”Bukh Coolant VCS Ready Mixed” or the concentrate ”Bukh Coolant VCS”, which ensure the protection of the cooling system components from corrosion, ageing, swelling and cracking, thereby ensuring optimal engine lifetime.
Over time the corrosion protection additives become less effective, and consequently the coolant must be changed at regular intervals to maintain sufficient protection of the engine. The latest Service Protocol that specifies service intervals can be found at volvopenta.com.

Coolant, Mixing
It is extremely important that the system is filled with the correct coolant concentration; refer to Technical Data, page 132. The coolant should be mixed with distilled, deionized water. For Bukh specified water requirements; refer to Technical Data, page 132.
NOTICE! If water quality can not be guaranteed, use ready mixed coolant.
Coolant Level, Checking and Topping Up
WARNING!
Do not open the coolant filler cap when the engine is hot, except personal injury. Steam or hot fluid could spray out.
1 Turn the filler cover slowly counter-clockwise and
release any pressure from the system before removing the cover completely.
in emergencies as this could cause serious
2 Top the coolant up as necessary. The coolant level
shall be between the MAX and MIN marks on the expansion tank.
3 Screw the filler cover on.
Seawater System
The raw water system is the engine's external cooling system. On engines with drives, the raw water pump sucks in water via the drive, through the control system's oil cooler to the raw water pump. The water then passes through the raw water filter before being pumped through the fuel cooler, intercooler, engine oil cooler and heat exchanger. Finally the water is fed out through the exhaust elbow, where it is mixed with the exhaust gases. On engines with reverse gears, the raw water pump sucks in water via a raw water intake, after which the water passes a raw water filter (extra equipment) before being pumped through the intercooler, heat exchanger, engine oil cooler and gearbox oil cooler. Finally the water is fed out through the exhaust elbow, where it is mixed with the exhaust gases.

WARNING!
Risk of water entry. Water will flow into the boat if any hose,
plug etc. located below the waterline is removed when the boat is in the water. Always close the sea cocks. If the boat does not have sea cocks the water flow must be blocked in a safe manner. If this is not possible, the boat must be drawn up on land before work starts.
Seawater System, Draining
WARNING!
Risk of water entry. Close the seawater cocks before doing any work on the seawater system.
To prevent frost damage, the raw water system must

1 Close the sea cock where fitted.
2 Open the drain stop cock (1) by unscrewing it
carefully.
3 Drain the coolant into a container. Screw in the stop
cock by hand.
4 Move the hose on the stop cock (1) and connect to
stop cock (2). Open stop cock (2) and drain all coolant. Close the stop cock.
5 Move the hose to stop cock (3).
Open stop cock (3) and drain all coolant. Close the stop cock.
