FUEL SYSTEM see page 24 for a typical Always fit a fuelwater separator in the fuel supply system Water in the fuel can seriously damage the
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
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 Drawing 20206421 illustrating recommended wiring for this pump can be supplied upon FILTER The fuel filter is a spin on type Remove by
turning when
viewed from below

Fresh water circulates through the engine and on to a where it is cooled by sea water which is the cooling tubes The sea water is then injected into
the exhaust system see THE FRESHWATER SYSTEM
New engines are supplied with the freshwater drained off The
following instructions must be followed to fill the system
a Mix up in a clean bucket a 33 to 50 antifreeze to Tap
freshwater solution see page 10 For the volume required
see technical specification page 4
b Check that the drain tap or plug is turned off see fig 2l

of the heat exchanger or header tank with the filler cap
removed see fig 2m
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
Run the engine for 5 minutes on no load out of gear and
check coolant level Top up as Check system for leaks
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 Fig 2l
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 Fig 2m
k Antifreeze solutions should be drained off every 2 years and replaced with a new When draining fresh water system ensure the engine has cooled
sufficiently to prevent scalding from 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 system
Yachts and Launches with Heat Exchanger Cooling
It is essential that a 33 to 50 mixture is used This not only stops freezing up in winter but it
prevents overheating and warranty is invalid unless the correct ratio is of ethylene should not exceed 50
The antifreeze in the fresh water system enables the boiling point of water to rise to 124C with a 13 psi 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
Heat working on the sea water system ensure that the sea cock is in the It is very important that the correct sea water flow is maintained to cool
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 2h
2 Withdraw the rubber impeller from its drive shaft as shown See diagram 2i
3 Check impeller for cracks in the rubber excessive wear or lost vanes Replace Fig 2h

65 AMP ALTERNATOR Heat Exchanger tension must only be checked with the engine switched off
1 On heat exchanger cooled engines a single 65 amp is fitted as standard
This alternator is adjusted as follows
2 The belt tension is adjusted by swinging the alternator outboard as it
pivots on its support bolts
3 With the engine stopped loosen the support bolts and the link adjusting
4 Push alternator outboard to tension and tighten link bolt Check that the
depression of the belt at position shown is approximately 12 or 12 mm
when pushed down firmly by thumb Tighten support bolts
5 Belt tension should be regularly checked especially during the first 20
hours of running in a new belt as stretching Amp alternator option
The same method applies as outlined above but final tensioning must be by
hand only Over tensioning will cause premature failure of INTAKE FILTER
These engines are fitted with an air intake filter which should be checked every season and changed every 2 years
or sooner if badly clogged If badly clogged check more often

a The engine oil and oil filter should be changed at the end of the season rather than in the spring See section 2
b The closed circuit system should contain a 30 to 50 solution of antifreeze to water 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 sea water or raw water circuit is now protected by Ensure instrument panel is well protected and give the key switch a spray of WD 40 or With
the engine stopped disconnect the battery always disconnect the negative cable first and reconnect the
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

SECTION installation details contained herewith are basic guidelines to assist installation due to great diversity 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 whilst following 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
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
To ensure vibration free operation the engine must be installed on 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 should be fitted Flexible couplings do not accommodate The mating faces of the gearbox and tailshaft must be checked they must
be parallel and concentric to within 0005 must be checked for parallel A and concentric B misalignment using
a set of feeler gauges
To obtain accurate alignment the flexible mountings must be adjusted 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 engine movement and
vibration Pack under the flexible mount with
steel shims securely bolted into the engine bearer
2 The pillar stud on the flexible mount is secured into position by the 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 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 31inchesHg 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
BV1903 50mm 50mm
High rise water injection bend SS 50mm 50mm
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 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
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
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 See 7
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 This can cause poor starting See 12
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
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
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 the vessel
5 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
All Beta engines can be fitted with the engine tappings
to allow the hot water from the closed system to circulate through a which in turn heats up domestic tappings on this range of engine are shown
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 and return pipes or sloping down in a continuous fall towards
the calorifier This avoids air pockets being created
3 Extra care must be taken when first filling circuit system with 50 antifreeze to as the engine may appear to be full but it 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 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 the calorifier then very carefully open bleed valve see manufacturers instructions or
if none is provided then very carefully 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
ingress of water

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

The BETA CONTROLLER is an integrated battery charging external regulator It
is designed to be used with Beta s 70 and 100am p 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
Beta Controller has been designed
for mounting off the engine in a location
away from vibration water Ideally as there is a
charge mode status LED the unit should
be positioned to allow for inspection of

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
