Change gearbox oil or ATF See separate gearbox manual
Check electrical equipment condition of hoses and belts replace as oil
Engine oil should be MILL2104C or have properties of API CCCDCE grades
The following table gives grades of oil required for various ambient TEMPERATURE SINGLE GRADE MULTI GRADE
Below 0C SAE 10W SAE 15W40
0C TO 25C SAE 20 SAE 15W40
Above 25C SAE 30 SAE 15W40
Note A good quality 15W40 multigrade oil as used in most diesel car engines will meet
these requirements Do not use Turbo Diesel Oil or engine oil level Fig 2a
For quantities of oil required see section marked checking the engine oil level do so before starting or
more than five minutes after stopping
1 To check the oil level draw out the dipstick wipe it clean
reinsert it and draw it out again Check to see that the
oil level lies between the two notches
2 If the level is too low add new oil to the specified level
Do not Fig 2b
When using an oil of different make or viscosity from the
previous one drain old oil Never mix two different types of
oil Engine oil should be changed after first 50 hours running
time and then every 250 hours or every year Oil filter is a
cartridge type mounted on the starboard side of the ENGINE OIL
1 Run the engine for 10 minutes to warm up the oil
2 Your engine is provided with a sump drain pump
Unscrew the end cap on the end of the pump optional
turn the tap to on Use the hand pump as shown to pump
out the oil into a bucket Turn the tap to off position and
replace end cap see Fig 2d
3 Unscrew the oil filter and replace with a new one
see Fig 2c Fig 2c
Note It is best to have a plastic bag wrapped round the
filter to catch any oil left in the system Always keep
your bilges clean Before screwing in the new filter
spread a thin film of oil round the rubber gasket to
ensure a good seal and screw in hand tight
4 Fill the engine with new oil as described above
Sump Pump
End Cap Optional
Fig 2d
CHECKING GEARBOX OIL LEVEL
1 The gearbox is fitted with a dipstick and oil filler
plug see fig 2e
2 Each engine is supplied with a gearbox operators
manual which specifies the type of lubricating oil
to be used the capacity and frequency of
changing of the oil
3 New engines are normally supplied with the
gearbox topped up with lubricant but check the
level before starting the engine for the first
time
4 The oil can be changed via the drain plug at the
bottom of the box or sucked out with a hand
pump via the filler plug
5 A guide to the type of oil to be used is as follows
Gearbox filler dipstick Fig 2e
Gearbox type Lubricant Capacity approx
PRM260 Use Engine Oil 15W40 15 litres
ZF25M Use Automatic transmission fluid 075 litres
ZF25H Use Automatic transmission fluid 20 litres
See separate gearbox manual for further details
FUEL If a fuel supply shutoff valve is fitted do not use a taper tap only use a ball valve tap The
ball valve type are more reliable and less likely to let air into the fuel system
Be sure to use a strainer when filling the fuel tank Dirt or sand in the fuel may cause
trouble in the fuel injection pump
Always use diesel fuel
Do not use kerosene which is very low in cetane rating and adversely affects the
engine
Be careful not to let the fuel tank become empty or air can enter the fuel system
necessitating bleeding before next engine start
The fuel lift pump will only lift fuel through 025 metres If this is insufficient then an
electric fuel lift pump must be fitted
The fuel return must be led back to the top of the fuel tank with a loop to prevent drain
down see fig 3e
FUEL FILTER The fuel filter is a spin on type Remove by
turning when viewed from below
2 Replace the fuel filter cartridge every 750 hours
See fig 2f
3 Apply fuel oil thinly over the gasket and tighten
into position hand tight
4 Bleed as detailed see initial start up
5 Check for leaks
6 Do not get fuel on the flexible mounts
Fig 2f
range of engines are normally fresh water cooled This water circulates through the engine and on
to a heat exchanger where it is cooled by sea water which is pumped through the cooling tubes The
sea water is then injected into the exhaust system see fig 2g
KEEL COOLING is an option In this system the freshwater is pumped through the engine and then
through a cooler built into the side of the boat where it is cooled by heat transfer before returning to the
engine see fig 2h 2i 2j The ideal keel cooling tank should have
a Baffle continuously welded to outer skin and close fitting on inner skin
b Be thin in section to allow good mixing of the water over the cool outer surface
c Air bleed valves should be fitted on both ends

New engines are supplied with the freshwater drained off The must be followed to fill the system
a Mix up in a clean bucket the correct strength and volume required of
solution see notes page 4
b Check that the drain tap is turned off see Figs 2k 2l
c Fill engine with freshwater anti freeze solution through the top of the
heat exchanger or header tank with the filler cap removed see Fig
d Fill header tank to the top of the filler neck and replace cap
Press down firmly on filler cap and hand tighten in a
clockwise direction Fig 2l BV3300 BV3800
Note For keel cooled engines a much larger quantity solution is required depending on the size
of the keel cooling tank refer to the builder
e Run the engine for 5 minutes on no load out of gear and
check coolant level Top up as Check system for leaks
Note For keel cooled engines it is very important to bleed all the air out of
the system before the engine is run on load check with builders
a calorifier is fitted care must be taken to see that this is also full of coolant and
all the air is expelled See calorifier fitting notes under Section 3
Fig 2m
g If a calorifier is fitted care must be taken to see that this is also full of coolant and all the air is
expelled See calorifier fitting notes under Section 3
h Run the engine on one third load for 15 minutes preferably with the boat tied up As the system
warms up coolant may be expelled from the overflow pipe into the bilge Stop the engine and allow
the engine to cool down before removing the pressure cap and top up the coolant to 1 below the
filler of the pressure cap when the engine is hot can cause severe injury from scalding hot water
under pressure Always allow the engine to cool and then use a large cloth when turning the cap to the stop This allows the pressure to be released
Press firmly down on the cap and
continue to turn anticlockwise to release the cap
i Repeat h if coolant level is more than 1 inch below the base of the filler neck when the engine has
cooled down
j Run engine on 23 full load for 20 minutes check for leaks and repeat i
k Antifreeze solutions should be drained off every 2 years and replaced with a new When draining the fresh water system ensure the engine has cooled
sufficiently to from hot pressurised water Prior to draining a cold engine remove the filler cap from the
header tank and then open the water drain tap This allows the water to drain freely from the and Launches with Heat Exchanger Cooling
It is essential that a mix of 33 to 50 mixture is used This not only stops freezing
up in winter but it prevents overheating and corrosion The warranty is invalid unless the correct
ratio is used
Canal Boats with Keel Cooler
A 33 antifreeze to water mixture is recommended to give protection against very cold of 15C and to allow the water temperature switch to be activated
This antifreeze will
also give the engine internal protection against corrosion For keel cooled engines the total must be taken into ie engine volume plus skin tankkeel
cooler of ethylene should not exceed 50
All engine types
The antifreeze in the fresh water system enables the boiling point of water to rise to 124C with a
95kPa pressure cap fitted The water temperature alarm switch will however be activated at 95 to
100C If no antifreeze or a very weak solution is used then the water temperature switch may not be
activated before coolant is lost
SEA WATER PUMP AND COOLING SYSTEM
Heat engines Fig working on the sea water system ensure that the sea
cock is in the off position
1 It is very important that the correct sea water flow is
maintained to cool the closed circuit system of the engine
The key component in this system is the sea water pump
impeller This should be checked every year by removing the
circular plate see fig 2n BF2803 fig2o BV3300
BV3800
2 Withdraw the rubber impeller from its drive shaft
3 Check impeller for cracks in the rubber excessive wear or
lost vanes Replace with a new impeller as necessary
Note If any pieces of rubber impeller are missing then they
must be found as they are most likely to be trapped in the
entrance to the heat exchanger cooling stack See Cleaning
Tube Stack
Fig 2o
CLEANING THE HEAT EXCHANGER TUBE STACK AND REPLACING WASTING ZINC ANODE
Fig 2p
1 The wasting zinc anode should be replaced every year The anode is
attached to the bolt inserted in the forward end cap of the heat exchanger
See fig 2p BV3300 BV3800 shown
2 Unscrew the bolt and replace the complete unit with a new one
3 Check for leaks
4 It is possible for fine sea weed and other debris to get past the inlet filter and
into the tube stack This should be removed and cleaned See fig 2q
5 Drain off coolant into a bucket
6 Unscrew the 8 end cap retaining bolts four each end of the tube stack
Remove the O rings and pull out tube stack Clean tube stack and end
caps Note the BF2803 has one bolt on each endcap
7 Reassemble using new O rings Do not overtighten end cap bolts and
make sure the tube stack is the right way round
8 Refill engine with solution and run engine up to
temperature to check for leaks Fig 2q
ALTERNATOR DRIVEBELT TENSIONING Heat exchanger Fig 2r
1 Belt tension must only be checked with the engine switched off
These engines are usually fitted with a single belt to drive the 65 amp
battery charging alternator heat exchange and the fresh water
circulating pump
2 The belt tension is adjusted by swinging the alternator outboard as it
pivots on its support bolt
3 With the engine stopped loosen the lower support bolt and the link
adjusting arm held by the top bolt
4 Push alternator outboard to tension and tighten link bolt Check that
the depression of the belt is approximately 12 or 12 mm when
pushed down firmly by thumb See fig 2r Tighten link bolt then lower support bolt
5 Belt tension should be regularly checked especially during the first 20 hours of running in a new
belt as stretching occurs

AIR INTAKE FILTER
These engines are fitted with an air intake filter which should be checked every season and changed
every two years Check and change more often if badly clogged
Air filter BV3300 BV3800 shown
Fig no circumstances should the battery be disconnected or switched off when the engine is running
This will seriously damage the AND WIRING
See installation notes page 28
GENERAL The panel must be protected from rain and sea water see installation Sea water entering the key
switch will eventually cause corrosion and could result in the starter motor being permanently
energised and burning out Spray keyswitch every month with WD 40 or Check batteries for acid level and top up if required For low maintenance and gel
batteries see
manufacturers Loose spade terminal connections are the most common cause for electrical faults check on a
regular bases see maintenance Engine loom plug and socket connections should be packed with Vaseline to prevent corrosion
plastic shrouds should be checked to be overlapping and connection should be made secure with a
cable tie This will help prevent the ingress of water and keep the connection AND LAYING UP
Heat Exchanger Cooled Engines Left Afloat and Ashore
a The engine oil and oil filter should be changed at the end of the season rather than the spring See
section 2
b The closed circuit system should contain a 5050 solution of antifreeze this also applies to warm
and tropical For cold climates where the air or water temperatures can fall below 3C the sea water circuit must
be protected in addition to the fresh water system This is best achieved as follows
i Close the inlet seacock to the engine engine stopped
ii Disconnect the sea water inlet pipe and dip it into a small bucket containing 5050 antifreeze
solution
iii Start the engine out of gear and run for 5 to 10 seconds until the antifreeze is used up and
can be seen coming out of the exhaust outlet
iv Shut engine off and reconnect the inlet pipe to the seacock
The seawater or raw water circuit is now protected by antifreeze Remove sea water pump
impeller store
d Ensure instrument panel is well protected and give the key switch a spay of WD 40 or With the engine stopped disconnect the battery always
disconnect negative cable first reconnect
negative cable last and take it ashore for trickle charging and top up as necessary If AC power is
available then this can be done on the boat
f Fuel tanks should be kept full during the lay up period to eliminate water condensation in the tank
Water entering the fuel injection system can cause considerable UP ASHORE
a Change the engine oil before the boat is taken out of the water Warm engine oil is much easier to
pump than cold
b to f should be followed as above
LAYING UP CANAL BOATS WITH KEEL items a b d e and f Item c does not apply Special care must be taken to ensure that the
whole cooling system has a 30 antifreeze solution and this includes the calorifier circuit
If the system has been topped up or refilled then run the engine for 10 to 15 minutes on load if possible
to get the solution circulated throughout the cooler and 13

Electrical fault finding trouble shooting engines built after July 2005 only
The following chart is compiled to aid diagnosis of electrical faults based on the Beta 1090hp range of
engines If your engine was built before July 2005 contact Beta Marine for the relevant shooting sea specification engines heat exchanger cooled are
supplied with a single port side supplying power to starter battery and control canal specification engines keel cooled are supplied with twin
1st alternator mounted port side supplying power to starter battery and control panel
2nd alternator the standard mounting position for this is above the engine on the starboard side or
below 1 alternator on 75 90hp supplying power to the domestic battery system
Both of these alternators work if the domestic battery system is disconnected the engine
will still run correctly but

SECTION installation details contained herewith are basic guidelines to assist installation due to the of marine craft it is impossible to give
definitive instructions Therefore Beta Marine can accept
no for any damage or injury incurred during the installation of a Beta Marine engine these guidelines
All engines shall be placed within an enclosure separated from living quarters and installed so as
to minimise the risk of fires or spread of fires as well as hazards from toxic fumes heat noise or
vibrations in the living quarters
Unless the engine is protected by a cover or its own enclosure exposed moving or hot parts of
the engine that could cause personal injury shall be effectively shielded
Engine parts and accessories that require frequent inspection and
or servicing must be readily accessible
The insulating materials inside engine spaces shall be not
MOUNTING Fig 3a
To ensure vibration free operation the engine must be installed beds extending as far forward and aft as possible and well
braced to form an integral part of the hull
The engine must be installed as low as possible on the flexible mount
pillar stud This will limit vibration and extend the life of the flexible mount
If necessary fit spacer blocks below the mounts
A flexible coupling must be fitted for all engines which are Flexible couplings do not accommodate bad alignment The
mating faces of the gearbox and tailshaft must be checked for must be parallel and concentric to within 0005
Fig 3b
Alignment must be checked for parallel A and concentric using a set of feeler gauges
To obtain accurate alignment the flexible mountings must be alignment is attained and the mountings must be locked in mounts are tightened alignment
must be rechecked Coupling can
now be fitted in accordance with instructions supplied with Do not set the engine feet high up the flexible mount pillar stud This will cause
excessive and vibration Pack under the flexible mount with steel shims securely bolted into the The pillar stud on the flexible mount is secured
into position by the lower locknut do not forget to
tighten this Also ensure that the stud is not screwed too far through the mounting body so that it
can touch the mounting bearer This will cause vibration and knocking noises which are very
hard to A correctly installed engine as described in this handbook will meet the exhaust emission
requirements of Directive 200344EC amending the Recreational Craft Directive 9425EC
b For compliance with exhaust emissions requirements engines must have correctly installed
exhaust systems To ensure exhaust emissions are kept within permissible limits it is most
important to reduce exhaust back pressure to a minimum whilst ensuring exhaust is
adequately muffled Back pressure increases as exhaust length increases and from bends in
the exhaust system The exhaust back pressure measured with the exhaust system connected
and the engine running at full speed must not exceed 80mmHg 31 inches Hg 42 inches
WG The correct measuring point is at the position where the exhaust connects to the exhaust
manifold That is before the water injection elbow or dry exhaust Exhaust hose should be matched to the following injection bend sizes
BF2803 BV3300 60mm 60mm 60mm
Typical Yacht Maximum sea water level when healed
on the centre line of the boat
300mm minimum
Normal sea water at least 10 of
propeller diameter for tip
clearance to hull
If a rope cutter is fitted allow approximately for
movement of engine see Fig 3c
1 One of the most common problems with engine installation is water entering the exhaust
manifold from the exhaust system by syphoning This can occur when the point of water
injection X on the engine is close to or below the water line Water entering the pistons
can cause bent con rods emulsified engine oil and a wrecked fuel pump Its best
avoided
2 The diagram shows a typical installation It is essential that the small black rubber hose
connecting the heat exchanger with the injection bend is removed and replaced by a
hose marked a This must be of sufficient length to supply either a T piece or an anti
syphon valve sited at least 300mm 12 inches above the water line and on the centre
line of the boat The pipe then returns to the injection bend and the sea water is
pumped down the exhaust pipe
3 The exhaust back pressure should not exceed 31 inches of Hg
DRY EXHAUST SYSTEM
The exhaust system installed in a canal boat or work boat with a dry exhaust should be 2
minimum ID The engine is fitted with a 2 BSP male connector when a dry exhaust system is
specified A flexible exhaust bellows and dry exhaust silencer should be used It is up to the
installer to work out his own pipe run but care should be taken as follows
1 Ensure that rain water cannot enter the
exhaust port and run back down the system
flooding the silencer and eventually the
engine Fig3d
2 The system should be lagged if there is any
danger of the crew getting near it
3 A dry exhaust system will give off
considerable heat and suitable ventilation
must be provided
4 The exhaust back pressure should not
exceed 31 inches of Hg
Fig 3d
Fig 3e
1 The mechanical fuel lift pump is fitted to all engines as standard but if a suction head of 025m is
required then an electric fuel lift pump must be fitted ask your dealer or Beta Marine
2 It is very important that the excess fuel from the injectors is fed back to the fuel tank and not back to
any point on the supply line This will help prevent air getting into the system
3 Fuel pipe sizes are Supply mm Leak off mm
8 8
4 Any fuel leaks in the system are likely to cause poor starting and erratic running and must be
corrected A fuelwater separator must be installed
6 The fuel return leak off pipe must loop down to be level with the bottom of the tank before it enters
the top of the tank see 12 This prevents fuel drain down
7 Fuel lines and hoses must be secured and separated or protected from any source of significant heat
The filling storage venting and fuel supply arrangements and installations must be designed and
installed so as to minimise the risk of fire and explosion Flexible fuel hoses connecting the engine to
fuel tank supply and return lines must meet the requirements set in standard ISO as required by your surveyor INLET SYSTEM Heat exchanger cooled
engines
Your engine is fitted with a gear driven sea water pump which sucks in seawater or raw water to cool the
closed circuit system via the heat exchanger Fig 3f
1 It is very important that the seawater inlet should
have a strainer system either built into the sea cock
or a high level system with visual inspection glass
as shown mounted just above the water line
2 The inlet sea cock and pipe work to the sea water
pump should be 25mm ID or 1 minimum
3 Good access to the inlet sea cock is essential so
that plastic bags or seaweed trapped in the intake
can be poked out
4 All pipe work should have approved marine steel hose clips Any loose clamps or can cause flooding and sinking If water is required for stern tube
lubrication then this should be taken from a T piece in the pipe
going from the heat exchanger outlet to the water injection bend
6 Scoop type water pickups should never be used as water will be forced through the pump and into
the exhaust system whilst the vessel is in motion This is very dangerous as the exhaust will and raw water will back up into the engine through the
exhaust valve Catastrophic failure will result
as soon as the engine is The maximum lift of the sea water pump is 2m
Keel cooled
1 The supply pipe to the keel cooler should be 32mm bore and the return 32mm bore 28mm supply
34mm return on BF2803
2 The tank size should have a surface area x exposed to the sea water or canal water of 025 x the
bhp of the engine sq ft of cooling area required For canal boats this should be adequately baffled and
a vent provided to expel any air The supply hot water goes in at the top of the tank and the return
comes out of the bottom Also refer to cooling tank notes on page 10
1 Baffle continuously welded to outer
skin and close fitting on inner skin
2 The tank should be thin in section to
allow good mixing of the water over the
cool outer surface
3 Air bleed valves should be fitted both SYSTEM Fig 3g All BF2803
All Beta engines can be fitted with the engine tappings to allow the
hot water from the closed fresh system to a calorifier tank which in turn heats up domestic tappings on this range of engine are shown below
1 The big problem with a calorifier is to remove all the air from the
system If this is not achieved then they dont work
2 Try and keep the supply b and return pipes a either horizontal
or sloping down in a continuous fall This avoids air pockets Extra care must be taken when first filling the calorifier with 50 antifreeze to water
solution as the engine may
appear to be full but it soon disappears into the calorifier pipe work
Run the engine off load for 10 minutes then check the level as
described in Filling The Fresh Water System
Also check to see if the pipe going to the calorifier is getting warm
after 15 minutes Top up the water level as required and run for
another 10 minutes then repeat
4 If the water level is steady but no warm water is getting to then very carefully open the calorifier bleed valve instructions or if none is
provided then very carefully Fig 3h BF2803 HE
loosen the jubilee clip securing the supply pipe to the calorifier Air
should escape Refasten securely when no further bubbles are not do this when the engine is hot as scalding hot water may be forced out of the pipe

has 4 panel options 2a
2abD or 2abV or 2abVW
The engine harness is common to all
1 These panels must not be installed where sea water spray can get at them A suitable flap or cover
must be fitted
2 Panels must be fitted in a location where the helmsman can either see or hear the alarm system
3 For standard wiring diagrams see following pages
4 Extension looms longer than 3m 10 feet As an option Beta can provide various lengths of
extension looms for runs of over 3m but this kit includes a start relay to overcome the voltage drop
See drawing 30058520
5 All electrical equipment must be protected from sea water Sea water or rust in the starter warranty Care must be taken when pushing the two halves
of the plug together to ensure
that individual pins do not push out To prevent corrosion and assist in assembly we recommend that
the plug is packed with petroleum jelly Vaseline and then carefully pushed together The plastic boots
should cover both halves and overlap A cable tie is then put round to hold the two halves in position
and help prevent any ingression of water
6 All cables must be adequately clipped and protected from abrasion
7 Electrical systems shall be designed and installed so as to ensure proper operation of the craft under
normal conditions of use and shall be such as to minimise risk of fire and electric shock
8 Attention shall be paid to the provision of overload and shortcircuit protection of all circuits except
engine starting circuits supplied from batteries
9 Ventilation shall be provided to prevent the accumulation of gases which might be emitted Batteries shall be firmly secured and protected from

1 Keyswitch standard panel keyswitch can be used to tap off a switched positive ignition feed to
power additional gauges In this way these gauges will only be live whilst the engine is
running the engine is starting or the heaters are being used
For silver keyswitches the terminal to achieve this ignition switched positive is marked AC
For black keyswitches the terminal to achieve this ignition switched positive is marked 1554
For panels without any keyswitch gauges can be driven from the 1mm2 brown wire at the 11 way connector terminal 4 This is a low power switched
positive power required from this connection must be fed through a relay as noted below
Note these keyswitch terminals are rated at 10 amps maximum since they are for panel and alternator feeds Beta Marine recommends any from these
terminals must be fed through a relay This relay should then be
connected to its own fused positive supply directly from the engine battery Beta
drawing 20206421 illustrating the wiring of a typical electric fuel lift pump with relay can be supplied upon request

BETA CONTROLLER
SEA SPEC ENGINES
The BETA CONTROLLER is an integrated battery charging external regulator It
is designed to be used with Betas 70 and 100amp Iskra system utilises a three stage charging which optimises the rapid
charge of battery systems
The first stage A mode is a boost charge which is indicated by the indicator LED
showing red
The second stage B mode is where the voltage is kept at a high level and where
the current is between 10 and 95 of the nominal alternator current the LED
shows orange
The third and last stage C mode is intended for maintenance of battery voltage
only When the alternator current is under a predetermined value for a time greater
than 2 minutes the regulating mode is changed from B to C mode
The system automatically adjusts the charge mode to suit the load and is set in our
works for conventional leadacid batteries It can easily be reset for deep cycle or
gel batteries A more detailed specification can be obtained from BETA MARINE
