Beta 28, Beta 30, Beta 35 & Beta 38 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.
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.
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. J A Growcoot, C.E.O, Beta Marine Limited. D Fuel i) Fuel Lines NOTE: Recreational Craft...
Therefore Beta Marine can accept no responsibility for any damage or injury incurred during the installation of a Beta • Engine parts and accessories that require frequent Marine Engine whilst following these guidelines.
ENGINE INSTALLATION AT AN ANGLE Beta Marine propulsion engines can be installed at angles When our engines are installed at varying angles of up to a maximum of 15° flywheel up or flywheel down inclination the normal markings on the dipstick should be when static, or can be run at up to 25°...

ALIGNMENT To obtain accurate alignment the flexible mountings must (Dial Test Indicator) mounted on a magnetic foot so that be adjusted until alignment is attained, and the they are aligned within 0.125mm (0.005”). (Obviously mountings must be locked in position. The engine / the propeller shaft must be centered in the stern tube and gearbox unit has to be aligned with the propeller shaft in running true - through the cutless bearing;...
FLEXIBLE OUTPUT COUPLINGS A flexible coupling is mounted on the gearbox output flange and is strongly recommended in almost every case. Flexible couplings do not resolve bad alignment, they are designed to absorb torsional vibrations from the propeller (transmitted along the propeller shaft). We normally offer two types: R&D with a flexible nylon disc and optional Clamp Coupling –...
EXHAUST SYSTEMS There are two main types of exhaust system: We recommend care when designing your exhaust system. The most important aspect is to ensure that water • Standard yacht - wet exhaust system with a water cannot enter the engine's combustion chamber from the injection bend and waterlock silencer exhaust system (this applies to both wet and dry exhaust •...
Page 14
HIGH-RISE EXHAUST In yachts, engines are mostly installed low down and If this is still not enough then you have to fit an often below the water line. There are several ways to ‘antisyphon’ / vacuum valve 50 cms above the 'loaded' avoid cooling water entering the engine.
Page 15
WATERLOCK / SILENCER You must always fit a waterlock / silencer to stop any injection bend, being as low as reasonably possible, so water in the exhaust system back filling the engine. The that all the water can drain down into it. The waterlock water lock should always be fitted at least 30 cms away should have sufficient capacity to hold an exhaust system from the injection bend and at least 30 cms below the...
SEA WATER INLET FOR HEAT EXCHANGER COOLED ENGINES Your engine is fitted with a gear driven sea water pump 3. Good access to the inlet sea cock from inside your which sucks in seawater (raw water) to cool the closed boat is essential so that plastic bags or seaweed circuit system via the heat exchanger.

EXHAUST BACK PRESSURE Keep exhaust systems to a minimum length and have Engine Exhaust Back Pressure gradual bends (NOT right angle elbows). Exhaust back Beta 10 to Beta 25 70 mm Hg pressure should be as low as possible; it is increased by long exhaust length and sharp bends.

STERN GEAR LUBRICATION A cooling water ‘bleed’ for stern gear lubrication of the Stern Bleed Feed cutlass bearing can be taken from the engine as it leaves the heat exchanger. Standard Exhaust with Stern Bleed Stern Bleed with Anti-syphon Valve Beta 10 to Beta 60 - can be connected to the heat Beta 75 upwards - need a ‘T’...
Page 19
DRY EXHAUST INSTALLATION a) An engine correctly installed in accordance with this The engine is fitted with a 1 ” BSP male connector handbook will meet the emission requirements of the stub as standard - Valid for exhaust systems up to 3 RCD (see back of manual).
When connecting the engine fitted (ask your dealer or Beta Marine). to the fuel supply and return lines, flexible fuel hoses must be used (next to the engine) and must meet the 3.
CALORIFIER SYSTEM All Beta engines can be fitted with the calorifier Heat Exchanger Calorifier System connections to allow the hot water from the closed fresh water / antifreeze system to circulate through a calorifier tank, which in turn heats up domestic water. Calorifier connections on this range of engine are shown.
ELECTRICAL INSTALLATIONS All our engines are supplied with 12 volt electric starting Care must be taken when pushing the two halves of as standard. We therefore supply the main components: the plug together to ensure that individual pins do not starter motor, battery charging alternator, fuel control fall out.

4. Battery size depends upon your requirements. For 5. If you require a domestic battery bank you will need to starter motor batteries the battery size should be based calculate your power requirements, and then multiply upon the starter motor requirements - table below, and that by the number of hours you will need this power never be of less capacity than the battery (before you are able to re-charge the batteries).
Page 24
BATTERY CABLES 1. Starter batteries should be as close to the engine as If the correct battery is selected but the engine will not practically possible. The reason for this is to ensure crank at sufficient speed after the inrush then that the maximum voltage from the battery is available (assuming battery cables are the correct size) the to the starter motor.

Section 2 GUIDELINES FOR OPERATION OF ENGINE IMPORTANT! CHECKS PRIOR TO INITIAL USE 1. Generally, a new engine has the oil and anti-freeze removed after the works test. Fill the engine with the correct oil and antifreeze (see sections on Engine oil and Cooling).

FILLING THE FRESH WATER SYSTEM New engines are supplied with the fresh water ‘coolant’ (e) Run the engine for 5 minutes on no load (out of gear) drained off. The following instructions must be followed to and check coolant level, this will help remove air from fill the system.
YACHTS AND LAUNCHES WITH HEAT EXCHANGER COOLING It is essential that a solution of fresh water and anti-freeze is The anti-freeze in the fresh water system enables the boiling used as engine coolant. The amount of anti-freeze must be point of water to rise to 124°C with a 13 psi pressure cap between 33% to 50%.
HEAT EXCHANGER TUBE STACK AND ‘WASTING ZINC ANODE’ 1. The wasting zinc anode should be checked regularly at least every six months and replaced every year or sooner, as necessary. The anode is attached to the bolt inserted in the end cap of the heat exchanger. Zinc anode See photo 46.
BELT TENSION WARNING! Adjuster bolt Belt tension must only be checked with the engine switched off. 65 AMP ALTERNATOR (HEAT EXCHANGER COOLED) These engines are fitted as standard with a single belt that drives both the 65 Amp battery charging alternator and the fresh water / engine coolant circulating pump.
AIR 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. ELECTRICAL MAINTENANCE WARNING! UNDER NO CIRCUMSTANCES SHOULD THE BATTERY BE DISCONNECTED OR SWITCHED OFF WHEN THE ENGINE IS RUNNING.
WINTERISING AND LAYING UP • a) The engine lubricating oil and lubricating oil filter Start the engine (out of gear) and run for 5 to 10 should be changed at the end of the season rather seconds until the anti-freeze is used up and can be than in the spring.
Trouble Shooting Beta diesels are very reliable if installed and serviced correctly, but problems can occur and the following list gives the most common ones and their solution.

Problem: Engine overheats - Keel cooling only Sometimes overheating is 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”...
