Welcome to MarineEngineManuals.com

In our store, you will find Workshop, Service, Installation, Parts, Owners, Information manuals and Schematics.

We can supply EPC software for Windows XP and Windows 7 packages to cover all models, for workshop and part manuals. These software packages are most suited for the professional or for the workshop.

Our collection of manuals are mainly for marine and some heavy equipment engines, current and old models. Our manuals and software are genuine and have been carefully selected.

How to find your manuals

Please select from the menu on the left your engine manufacturer, or use the search box on the top right hand of the menu bar to find your manuals. To search, you must use your engine model in different variations for better results, e.g., M17 or Sole M17, 4.108M or Perkins 4.108, or just use the engine manufacturer, e.g., Perkins, Bukh, Sole, etc.

We handpick and thoroughly check our electronic manuals before we put them up for sale. We also supply these manuals on soft copy DVDs at an extra cost. We ship worldwide. Please contact us to make the necessary arrangements.

Special arrangements can be made for "express courier" at a reasonable price, through your courier or ours. Do not hesitate to contact us for a price or to place an order.

Free knowledge: 12 Volt BATTERIES

Stray Current: (an explanation)

. Stray current is electricity that is flowing where it's not supposed to, mainly through: water, metal fittings on your boat, wet wood, damp surfaces, propeller shaft(s) etc. and can cause corrosion (technically known as electrolytic corrosion). Stray current corrosion is caused by a power source, such as your batteries or the shore power connection. The stray current can cause serious electrolytic corrosion damage, because of the relatively high driving voltages (shore power) stray current corrosion, can act far more quickly than the corrosion caused by dissimilar metals in contact (galvanic corrosion).

Common Ground Point: (ship's ground)

. Grounds from batteries, engine, switch-panel, negative bus bar, bonding system, auxiliary power generator, underwater ground plate, ship's 120-240AC Volt safety-ground, and LORAN/RADAR signal(s)-ground, must all be connected at one grounding point, this must be a heavy bus bar or bracket with bolted connections, this must be easy to access and must be located above bilge levels as practicable and be labeled as Common Ground Point(s)

Batteries: (know how)

WARNING! The hydrogen gas inside lead-acid batteries is explosive and can burn your skin and eyes. Avoid sparks or open flames and wash well after handling your battery.

The acid level inside the battery must cover the top of the plates. Letting the acid level below the top of the plates will cause serial battery damage. Use distilled water to top up the batteries. If distilled water isn't available, rain water can be used instead if it's clean from foreign particles. If rain water is going to be used then it must be filtered beforehand. . The battery is fully charged when the specific gravity of the electrolyte is between 1.245 to 1.300 in each cell. In a partially discharged battery, the specific gravity variation between cells must not vary by more than 0.050. The battery cells (plates) sometimes after been charged can have uneven (specific gravities) values, but after been discharged, for about 25% (from a full charge) they even out, if not then this battery need to be replaced

NOTE: If a battery has been left for a long time without been charged, it is possible for the acid to separate from the water and settled to the bottom, leaving a lower specific gravity electrolyte on the surface, or if you overfilled the battery then the electrolyte may be over diluted. Either of these situations can result in abnormally low readings and they don't necessarily indicate a weak or damaged battery cell.

. The battery voltage 'at rest' must be between 12.1 to 12.9 Volts a battery is 'at rest' when it isn't being used and hasn't received a charging or been discharged for at least 12 hours. a voltage above 12.9 Volts indicates that the battery is still settling after a charge, a voltage below 12.1 Volts indicates either a weak cell or a battery charge below 50% of capacity.

. Standard batteries have their life span shortened drastically by deep discharges, even to the 50% level. True deep cycle batteries (see below) function well with 50% discharges.

. To test the batteries, crank the engine for 3-5 seconds with each battery, the battery voltage must be above 9.5 Volts and steady whilst cranking. This test must be done after the engine has been run so that the engine oil has been circulated, you must disconnect the coil's '+' wire (Petrol engine) or turn the diesel fuel shut-off (Diesel engine) to prevent the engine from starting. Sometimes it's possible for a battery to fail this high current test while still being able to provide good storage capacity at lower currents. This can happen if the starter to the battery cable/connection, condition and size, are outside the factory's specifications.

. If an engine doesn't crank properly and or the battery voltage remains high, then there is a problem with the starting circuit or the starter motor.

. Note: Starter and electric winch motors will normally 'pull' a battery's voltage down to 9 or 10VDC while they're
operating. The battery should recover most of its voltage 'at rest' within seconds.
