Check coolant level Check battery fluid Check drive belt tension Ensure raw water inlet strainer is clear Check stern gland lubrication Drain off any water in fuel water separatorAfter The First 25 Hours Running Change gearbox lubricant See separate gearbox manual Check that all external nuts bolts and fastenings are tight See table for torque values Special attention should be paid to the flexible mount lock nuts these should be checked for tightness starting with lower nut first in each case If the lower nuts are found to be very loose then the alignment of the shaft to the gearbox half coupling should be rechecked Poor alignment due to loose flexible mount nuts will cause excessive vibration and knocking Check the belt tension on any second alternators fitted and adjust see page 11 Check ball joint nyloc nuts for tightness on both gearbox and speed control levers Grease both fittings all overAfter First 50 Hours Change engine lubricating oil Change oil filter Check for leaks on header tank tubestack Tighten end cap bolt if required Drain off any water in fuelwater separatorEvery 150 Hours If shallow sump option is fitted change engine lubricating oil and filterEvery

or additives Oil goesCHECKING ENGINE OIL LEVEL in hereFor quantities of oil required see section marked Technical Specification Page 4When checking the engine oil level do so before starting or more than fiveminutes after stopping1 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 notches2 If the level is too low add new oil to the specified level Do not overfill Fig using an oil of different make or viscosity from the previous one drain old Dipstickoil Never mix two different types of oil Engine oil should be changed after first50 hours running time and then every year or every 250 hours if sooner Oilfilter is a cartridge type mounted on the starboard side of the engineCHANGING ENGINE OIL1 Run the engine for 10 minutes to warm up the oil2 Your engine is provided with a sump drain pump Unscrew the end cap on the Fig 2b end of the pump 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 diagram 2c Sump Pump3 Unscrew the oil filter and replace with a new one See diagram 2d 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 End filter spread a thin film of oil round the rubber gasket to ensure a good seal Cap and screw in hand tight4 Fill the engine with new oil as described on the previous page5 Run the engine and check for oil leaks Fig 2c 7CHECKING GEARBOX OIL LEVEL1 The gearbox is fitted with a dipstick and oil filler plug see fig 2e2 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 oil3 New engines are normally supplied with the gearbox topped up with lubricant but Check the level before starting the engine for the first time4 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 Fig 2d oil filter removal5 A guide to the type of oil to be used is as follows Oil filler Gearbox Lubricant Capacity approx plug

Water in the fuel can seriously damage the injection system 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 Drawing 20206421 illustrating recommended wiring for this pump can be supplied upon requestFUEL FILTER REPLACEMENT1 The fuel filter is a spin on type Remove by turning anticlockwise when viewed from below2 Replace the fuel filter cartridge every 750 hours or every 2 years See fig 2g3 Apply fuel oil thinly over the gasket and tighten into position hand tight4 Bleed as detailed see initial start up5 Check for leaks6 Do not get fuel on the flexible mounts Fig 2g 8HEATING EXCHANGER COOLED Heat Exchanger CooledFresh water circulates through the engine and on to a heatexchanger where it is cooled by sea water which is pumpedthrough the cooling tubes The sea water is then injected intothe exhaust system see diagramFILLING THE FRESHWATER SYSTEMNew engines are supplied with the freshwater drained off Thefollowing instructions must be followed to fill the system Draina 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 4b Check that the drain tap or plug is turned off see fig 2lc Fill engine with freshwateranti freeze solution through the top of the heat exchanger or header tank with the filler cap removed see fig 2md 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 directione Run the engine for 5 minutes on no load out of gear and check coolant level Top up as necessaryf Check system for leaksg 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 3h 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 injuryfrom scalding hot water under pressure Always allow the engine to cool andthen use a large cloth when turning the cap anticlockwise to the stop Thisallows the pressure to be released Press firmly down on the cap and continueto turn anticlockwise to release the capi Repeat h if coolant level is more than 1 inch below the base of the filler neck when the engine has cooled downj Run engine on 23 full load for 20 minutes check for leaks and repeat i Fig 2mk Antifreeze solutions should be drained off every 2 years and replaced with a new solutionNote When draining fresh water system ensure the engine has cooled sufficiently to prevent scalding from hotpressurised water Prior to draining a cold engine remove the filler cap from the header tank and then open thewater drain tap This allows the water to drain freely from the system 9Yachts and Launches with Heat Exchanger CoolingIt is essential that a 33 to 50 mixture is used This not only stops freezing up in winter but itprevents overheating and corrosionThe warranty is invalid unless the correct ratio is of ethylene should not exceed 50The antifreeze in the fresh water system enables the boiling point of water to rise to 124C with a 13 psi pressurecap fitted The water temperature alarm switch will however be activated at 95 to 100C If no antifreeze or a veryweak solution is used then the water temperature switch may not be activated before coolant is lostSEA WATER PUMP AND COOLING SYSTEMHeat working on the sea water system ensure that the sea cock is in the offposition1 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 2h2 Withdraw the rubber impeller from its drive shaft as shown See diagram 2i3 Check impeller for cracks in the rubber excessive wear or lost vanes Replace Fig 2h 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 StackCLEANING THE HEAT EXCHANGER TUBE STACK AND ZINC ANODE1 The wasting zinc anode should be checked every six months and replaced every year or as necessary The anode is attached to the bolt inserted in the end cap of the heat Fig 2I exchanger See Fig 2j On most engines this is on the aft end2 Unscrew the bolt and replace the complete unit with a new one3 Check for leaks4 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 2k5 Drain off coolant into a bucket6 Unscrew the 2 end cap retaining bolts one each end of the tube stack Remove Zinc Fig 2j the O rings and pull out tube stack Clean tube stack and end caps Anode7 Reassemble using new O rings Do not overtighten end cap bolts and make sure the tube stack is the right way round8 Refill engine with solution and run engine up to temperature to check for leaks Fig 2k 10BELT TENSION ADJUSTING BOLTS65 AMP ALTERNATOR Heat Exchanger tension must only be checked with the engine switched off1 On heat exchanger cooled engines a single 65 amp is fitted as standard This alternator is adjusted as follows2 The belt tension is adjusted by swinging the alternator outboard as it pivots on its support bolts3 With the engine stopped loosen the support bolts and the link adjusting bolt4 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 bolts5 Belt tension should be regularly checked especially during the first 20 hours of running in a new belt as stretching occurs100 Amp alternator optionThe same method applies as outlined above but final tensioning must be byhand only Over tensioning will cause premature failure of componentsAIR INTAKE FILTERThese engines are fitted with an air intake filter which should be checked every season and changed every 2 yearsor sooner if badly clogged If badly clogged check more often 1 2 3 11MAINTENANCE no circumstances should the battery be disconnected or switched off when the engine is running This willseriously damage the AND WIRINGSee installation notes page 27General maintenance1 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 key switch every month with WD 40 or equivalent2 Check batteries for acid level and top up if required For low maintenance and gel batteries see manufacturers instructions3 Loose spade terminal connections are the most common cause for electrical faults check on a regular bases see maintenance AND LAYING UPHeat Exchanger Cooled Engines Left Afloat And Ashorea The engine oil and oil filter should be changed at the end of the season rather than in the spring See section 2b The closed circuit system should contain a 30 to 50 solution of antifreeze to water this also applies to warm and tropical climatesc 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 antifreezed Ensure instrument panel is well protected and give the key switch a spray of WD 40 or equivalente 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 boatf 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 damageLAYING UP ASHOREa Change the engine oil before the boat is taken out of the water Warm engine oil is much easier to pump than coldb to f should be followed as above 12 TROUBLE SHOOTINGBeta diesels are very reliable if installed

herewith are basic guidelines to assist installation due to great diversity of marinecraft it is impossible to give definitive instructions Therefore Beta Marine can accept no responsibility for any damageor 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 not MOUNTINGTo ensure vibration free operation the engine must be installed on extending as far forward and aft as possible and well braced to form anintegral part of the hullThe engine must be installed as low as possible on the flexible mount pillar studThis will limit vibration and extend the life of the flexible mount If necessary fitspacer blocks below the mountsA flexible coupling should be fitted Flexible couplings do not accommodate badalignment The mating faces of the gearbox and tailshaft must be checked foralignment they must be parallel and concentric to within 0005 must be checked for parallel A and concentric B misalignment usinga set of feeler gaugesTo obtain accurate alignment the flexible mountings must be adjusted untilalignment is attained and the mountings must be locked in positionOnce mounts are tightened alignment must be rechecked Coupling can now befitted in accordance with instructions supplied with Do not set the engine feet high up the flexible mount pillar stud This will causeexcessive engine movement and vibration Pack under the flexible mount withsteel shims securely bolted into the engine bearer2 The pillar stud on the flexible mount is secured into position by the lowerlocknut do not forget to tighten this Also ensure that the stud is not screwed too far through the mountingbody so that it can touch the mounting bearer This will cause vibration and knocking noises which are veryhard to findExhaustsa A correctly installed engine as described in this handbook will meet the exhaust emission requirements of Directive 200344EC amending the Recreational Craft Directive 9425ECb 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 bellowsWet Exhaust hose should be matched to the following injection bend sizes BV1903 BV2203Standard 50mm 50mmHigh rise water injection bend SS 50mm 50mm 23Typical Yacht Installation Maximum sea water level when healed on the centre line of the boat 300mm minimum Normal sea water levelAllow at least 10 ofpropeller diameter for tipclearance to hull If a rope cutter is fitted allow approximately for movement of engine see manufacturers 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 avoided2 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 pipe3 The exhaust back pressure should not exceed 31 inches of Hg 241 The mechanical fuel lift pump is fitted to all engines as standard but if a suction head of 025m isrequired then an electric fuel lift pump must be fitted ask your dealer or Beta Marine2 It is very important that the excess fuel from the injectors is fed back to the fuel tank and not back toany point on the supply line This will help prevent air getting into the system3 Fuel pipe sizes are Supply mm Leak off mm 8 84 Any fuel leaks in the system are likely to cause poor starting and erratic running and must becorrected immediately5 A fuelwater separator must be installed See 76 The fuel return leak off pipe must loop down to be level with the bottom of the tank before it entersthe top of the tank see 12 This prevents fuel drain down This can cause poor starting See 127 Fuel lines and hoses must be secured and separated or protected from any source of significant heatThe filling storage venting and fuel supply arrangements and installations must be designed andinstalled so as to minimise the risk of fire and explosion Flexible fuel hoses connecting the engine tofuel tank supply and return lines must meet the requirements set in standard ISO as required by your surveyor INLET SYSTEM Heat exchanger cooled enginesYour engine is fitted with a gear driven sea water pump which sucks in seawater or raw water to cool theclosed circuit system via the heat exchanger1 It is very important that the seawater inlet shouldhave a strainer system either built into the sea cock or ahigh level system with visual inspection glass asshown mounted just above the water line2 The inlet sea cock and pipe work to the sea waterpump should be 25mm ID or 1 minimum3 Good access to the inlet sea cock is essential so thatplastic bags or seaweed trapped in the intake can bepoked out4 All pipe work should have approved marine gradestainless steel hose clips Any loose clamps or badconnections can cause flooding and sinking the vessel5 If water is required for stern tube lubrication then this should be taken from a T piece in the pipegoing from the heat exchanger outlet to the water injection bend6 Scoop type water pickups should never be used as water will be forced through the pump and intothe exhaust system whilst the vessel is in motion This is very dangerous as the exhaust will eventuallyfill and raw water will back up into the engine through the exhaust valve Catastrophic failure will resultas soon as the engine is restartedNote The maximum lift of the sea water pump is 2m 25CALORIFIER SYSTEMAll Beta engines can be fitted with the engine tappingsto allow the hot water from the closed system to circulate through a calorifiertank which in turn heats up domestic tappings on this range of engine are shown1 The big problem with a calorifier is to remove all theair from the system If this is not achieved then theydont work2 Try and keep the supply and return pipes or sloping down in a continuous fall towardsthe calorifier This avoids air pockets being created3 Extra care must be taken when first filling thecalorifier circuit system with 50 antifreeze to watersolution as the engine may appear to be full but it soondisappears into the calorifier pipe work Run the engineoff load for 10 minutes then check the level asdescribed in Filling The Fresh Water SystemAlso check to see if the pipe going to the calorifier is getting warm Top up the water level as requiredand run for another 10 minutes then repeat4 If the water level is steady but no warm water is getting to the calorifier then very carefully open thecalorifier bleed valve see manufacturers instructions or if none is provided then very carefully loosenthe jubilee clip securing the supply pipe to the calorifier Air should escape Refasten securely when nofurther bubbles are seenCAUTIONDo 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 2b 2cDThe engine harness is common to all1 These panels must not be installed where sea water spray can get at them A suitable flap or covermust be fitted2 Panels must be fitted in a location where the helmsman can either see or hear the alarm system3 For standard wiring diagrams see following pages4 Extension looms longer than 3m 10 feet As an option Beta can provide various lengths ofextension looms for runs of over 3m but this kit includes a start relay to overcome the voltage dropSee drawing 300585205 All electrical equipment must be protected from sea water Sea water or rust in the starter willinvalidate warranty Care must be taken when pushing the two halves of the plug together to ensurethat individual pins do not push out To prevent corrosion and assist in assembly we recommend thatthe plug is packed with petroleum jelly Vaseline and then carefully pushed together The plastic bootsshould cover both halves and overlap A cable tie is then put round to hold the two halves in positionand help prevent any ingression of water6 All cables must be adequately clipped and protected from abrasion7 Electrical systems shall be designed and installed so as to ensure proper operation of the craft undernormal conditions of use and shall be such as to minimise risk of fire and electric shock8 Attention shall be paid to the provision of overload and shortcircuit protection of all circuits exceptengine starting circuits supplied from batteries9 Ventilation shall be provided to prevent

I do not sell or share any user data or anything else for that matter. The only personal information I save is in the site log which has a line for each page view which includes the IP address your browser sends in the header as well as which page you requested. I use this to block hackers and other bad actors. I do not use this raw data to create profiles on users. I periodically delete the log files. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
