It is probably better to totally drain up to a maximum of 15° flywheel up or flywheel down the sump, and completely refill the engine sump with the when static, and can be run at up to 25°... - Page 5 ALIGNMENT To obtain accurate alignment the flexible mountings must mounted on a magnetic foot so that they are aligned be adjusted until alignment is attained, and the mountings within 0.125mm (0.005”). (Obviously the propeller shaft must be locked in position. The engine / gearbox unit has must be centered in the stern tube and running true - to be aligned with the propeller shaft in two ways.
- Page 6 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 –...

Page 7: Exhaust Systems
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 1) 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 2) Dry exhaust system (see page 17) - Page 8 HIGH-RISE EXHAUST In yachts, engines are mostly installed low down and standard injection bend is too low then we can offer a often below the water line. There are several ways to high-rise injection bend that adds 15 cms to the height. avoid cooling water entering the engine.
- Page 9 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...

Page 15: Calorifier System
CALORIFIER SYSTEM All Beta engines can be fitted with the calorifier Heat Exchanger Calorifier System connections to allow the coolant from the closed circuit cooling system to circulate through a calorifier tank, which in turn heats up domestic water. Calorifier connections on this range of engine are shown. - Page 16 CANAL BOATS WITH KEEL COOLERS Most narrowboats on English canals have keel cooling, Narrowboats: With keel cooling the coolant (same fresh and this is standard for our ‘Green Line’ Narrowboats’ water / antifreeze solution as heat exchanger cooling) and ‘Wide Beamers’ (heat exchanger cooling is available flows around the engine and also the keel cooling tanks, as an option if required).

ELECTRICAL INSTALLATIONS All our engines are supplied with 12 volt electric starting will invalidate the warranty. Care must be taken as standard. We therefore supply the main components: when pushing the two halves of the plug together to starter motor, battery charging alternator, fuel control ensure that individual pins do not fall out. - Page 19 3. All our engines are supplied with one battery charging 4). Battery size depends upon your requirements. For alternator, sometimes two.

Page 20: Battery Cables
BATTERY CABLES 1. Starter batteries should be as close to the engine as If the correct battery is selected but the engine will practically possible. The reason for this is to ensure not 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. - Page 21 In this way these gauges will only be live whilst the alternator feeds Beta Marine recommend any additional engine is running, the engine is starting or the heaters are requirements from these terminals must be fed through being used.
