OPERATION AND MAINTENANCE MANUAL FOR THE FOLLOWING
BETA MARINE ENGINES BASED ON KUBOTA
WELCOME TO BETA MARINE
Thank you for purchasing a Beta Marine Engine. We have made this manual to provide
you with important information and recommendations to ensure trouble free and
economical operation of the engine.
As manufacturers we have obviously written this “Operators Maintenance Manual” from
our ‘involved technical viewpoint’ assuming a certain amount of understanding of marine
engineering. We wish to help you, so if you do not fully understand any phrase or
terminology or require any explanations please contact Beta Marine Limited or its
distributors and we will be pleased to provide further advice or technical assistance.
All information and recommendations given in this publication are based on the latest
information available at the time of publication, and are subject to alteration at any time.
The information given is subject to the company’s current conditions of Tender and Sale,
is for the assistance of users, and is based upon results obtained from tests carried out at
the place of manufacture and in vessels used for development purposes. We do not
guarantee the same results will be obtained elsewhere under different conditions.

ENGINE IDENTIFICATION
A full inspection of the engine must be made immediately on delivery to confirm that there is no damage. If there is
any damage then write this clearly on the delivery note and inform your dealer or Beta Marine within 24 hours. A
photograph would always help.
INITIAL RECEIPT OF THE ENGINE
The engine must be stored in a dry, frost free area and this is best done in its packing case. If storage is to be more
than six months then the engine must be inhibited (contact your dealer or Beta Marine). Failure to inhibit the engine
may result in the formation of rust in the injection system and the engine bores, this could invalidate the warranty.
ENGINE STORAGE
The engine serial number is shown on the rocker cover
label. It is also stamped on the crank case flange below
the fuel injection pump on the starboard side of the
engine.

Safety Precautions!
A Keep the engine, gearbox and surrounding area
clean, including the area immediately below the
engine.
B Drives - Power Take Off Areas
i) Gearbox Output Flange
The purpose of a marine diesel propulsion engine is to
provide motive power to propel a vessel. Accordingly
the gearbox output shaft rotates at between 280 and
2400 rev/min. This flange is designed to be coupled to
a propeller shaft by the installer and steps must be
taken to ensure adequate guarding.
ii) Forward End Drive
Engines are supplied with unguarded belt drives to
power the fresh water pump and battery charging
alternator. The installer must ensure that it is not
possible for injury to occur by allowing access to this
area of the engine. The three pulleys run at high speed
and can cause injury if personnel or clothing come in
contact with the belts or pulleys, when the engine is
running.
iii) Power Take Off Shaft (Engine Mounted Option)
Shaft extensions are available as an option and rotate
at between 850 and 3600 rev/min. If contact is made
with this shaft when the engine is running, injury can
occur.
C Exhaust Outlet
Diesel marine propulsion engines emit exhaust gases
at very high temperatures - around 400 - 500°C.
Engines are supplied with either wet exhaust outlet
(water injection bend) or dry outlet (dry exhaust stub)
- see option list. At the outlet next to the heat
exchanger/header tank, the exhaust outlet can become
very hot and if touched, can injure. This must be
lagged or avoided by ensuring adequate guarding. It is
the responsibility of the installer to lag the exhaust
system if a dry system is used. Exhaust gases are
harmful if ingested, the installer must therefore ensure
that exhaust lines are led overboard and that leakage
in the vessel does not occur.
DFuel
i) Fuel Lines
Diesel engines are equipped with high pressure fuel
injection pumps, if leakages occur, or if pipes fracture,
fuel at a high pressure can harm personnel. Skin must
be thoroughly cleaned in the event of contact with
diesel fuel.
ii) Fuel Supply Connections
Engines are supplied with 8mm compression fittings.
The installer must ensure that when connections are
made, they are clean and free of leaks.
EOil
The Beta propulsion unit is supplied with 2 dipsticks,
one for the engine and one for the gearbox. Ensure
dipsticks are returned and secure after checking, if not
oil leaks can cause infection when touched. All oil
must be removed from the skin to prevent infection.
F Scalding
An engine running under load will have a closed
circuit fresh water temperature of 85° to 95°C. The
pressure cap on the top of the heat exchanger must
not be removed when the engine is running. It can
only be removed when the engine is stopped and has
cooled down.
G
Transportation / Lifting
Engines are supplied on transportable pallets. Lifting
eyes on engines are used for lifting engine and
gearbox assembly only, not the pallet and associated
kit.
GENERAL DECLARATION
This machinery is not intended to be put into service until
it has been incorporated into or with other machinery. It is
the responsibility of the purchaser / installer / owner, to
ensure that the machinery is properly guarded and that all
necessary health and safety requirements, in accordance
with the laws of the relevant country, are met before it is
put into service.
Signed:
J A Growcoot, C.E.O, Beta Marine Limited.
NOTE: Recreational Craft
Where applicable, the purchaser / installer / owner and
operator must be responsible for making sure that the
Recreational Craft Directive 94/25/EC is complied with.

Section 1
Keel cooled engine, overheating is sometimes caused by:
a) Not fully venting the engine cooling system of air. It is
necessary to remove all air from the cooling system -
including the “skin” tanks and (if fitted) the Calorifier
and associated piping.
b) Incorrectly sized “skin” tanks that have been sized for
‘usual’ canal use, rather than maximum engine output
that can sometimes be required on fast flowing rivers.
An additional “skin” tank may need to be fitted; please
refer to our website: Inland waterways - guidelines:
keel cooling tank sizes.
INSTALLATION RECOMMENDATIONS FOR
KEEL COOLED ENGINES
The installation details are basic guidelines to assist
installation, however due to the great diversity of marine
craft it is impossible to give definitive instructions.
Therefore Beta Marine can accept no responsibility 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 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
non-combustible.
INSTALLATION RECOMMENDATIONS
The engine compartment needs air.
a) as air (oxygen) to burn the diesel fuel, and
b) as air to keep the engine cool (still hot at 100°C)
by ventilation.
It is important that the engine compartment has adequate
ventilation, and this is your responsibility. If there is no
ventilation the engine can overheat and damage can be
caused. As a general statement an engine will produce
radiated heat - approximately equal to 1/3of the engine
output power. Also the larger battery charging alternators
create lots of heat. (A symptom of overheating problems is
often black belt dust). If you have any doubts about the
temperature of your engine compartment please check
with a thermometer on a hot day, the maximum
temperature in the engine compartment should be less
than 70°C - the cooler the better!
Engine compartment ventilation is normally best with two
holes; an inlet allowing colder air to enter below to the
alternator and drive belts and a second outlet (about the
same size) for the hot air to rise and ventilate out from the
top of the engine compartment. Adequate ventilation must
be included with all installations. Many installations now
include a good quality reliable electric ventilation fan to
remove the hot air. The required air flow volumes in
m3/min = 0.05 x engine power in hp.

To ensure vibration free operation, the engine must be
installed and correctly aligned on substantial beds,
extending as far forward and aft as possible, well braced
and securely fastened 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.
To assist with engine replacement we offer ‘Special
Engine Feet’ manufactured to your dimensions, as an
optional extra to suit your existing engine bearers and
shaft alignment / installation.
WARNING!
• Do not set the engine feet high up the flexible mount
pillar stud. This will cause excessive engine movement
and vibration. Pack under the flexible mount with steel
shims securely bolted into the engine bearer.
• 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
bearer. This will cause vibration and knocking noises
which are very hard to find!

Beta Marine propulsion engines can be installed at angles
up to a maximum of 15° flywheel up or flywheel down
when static, or can be run at up to 25° when heeling.
However if you are considering installing above 12°
please contact Beta Marine or alternatively consider the 7°
down angle gearbox.
When our engines are installed at varying angles of
inclination the normal markings on the dipstick should be
disregarded. It is probably better to totally drain the sump,
and completely refill the engine sump with the
recommended quantity / volume of lubricating oil - noting
its position on the dipstick - and then marking the
dipstick accordingly (don’t forget to replace the oil filter).
If in doubt ask Beta Marine!
