Checking the raw water strainer

Check daily whether there is any dirt in the
raw water strainer.

Cleaning the strainer

Close the seacock before removing the lid
of the water strainer.

Clean the raw water strainer as often as is
necessary, depending on the pollution of
the waterways, but at least once every 6
months. A clogged raw water strainer will
result in excessive temperatures or over­heating of the engine coolant.

Check the sealing between the lid and
housing after cleaning and re-assembling
the strainer. An improperly sealed lid will
result in air sucked in by the sea water
pump which again will result in overheat­ing of the engine.

Checking electrolyte level

For conventional batteries it is required
to check the electrolyte level regularly.
Remove vent caps (taking care no spark
or open flame is nearby) and inspect the
level. Fluid should be 10 to 15 mm (3/8” to
5/8”) above top of all plates. If necessary
top up with distilled water. Replace vent
caps and charge the battery for 15 min­utes at 15 - 25 Amps to mix electrolyte.

Checking specific gravity

Measure the electrolyte specific gravity
of the individual cells with a commer­cial hydrometer. The hydrometer reading
(see table) indicates the state of charge.
Hydrometer reading of all cells should be
at least 1.200 and show less than 0.050
between high and low. If not, recharge or
replace battery. During checking the tem­perature of the electrolyte should prefer­ably be 20°C (68°F).

The gases emitted by the
battery are explosive! Keep
sparks and naked flames
away from the battery!

Do not allow battery acid to come into
contact with skin or clothing!
Wear protective goggles!

At full load (with the boat cruising) the
maximum engine speed should be about
3,200 RPM (see technical data page 60). If
the engine does not reach this speed, it is
being overloaded!
If this is the case, check the ship’s pro­peller for defects or irregularities, and
also to see that it is the correct pitch and
diameter.

Checking engine speed

The engine idling speed should be 840
rpm.
Allow the engine to warm up normally
(until the coolant temperature reaches at
least 60°C (140°F).) before checking and/
or adjusting the idling speed.
Check the engine RPM using a rev. coun­ter, or use the rev. counter fitted to the
control panel.

Adjusting engine idling speed

If the engine speed differs from that stated
above, it must be adjusted.
The engine idling speed can be reset
using the adjustment screw on the fuel
pump.

Running with protective fuel mixture

Connect the fuel supply pipe to a can filled
with a mixture of one (1) part of engine oil*
to nine (9) parts of clean fuel**. Use this
mixture to run the engine at no load for
approx. 10 minutes.
Stop the engine.

* Engine oil with protective properties.
E.g. Shell Super Diesel T 10W40
** Preferably water-free fuel.
Collect some fuel from the return pipe,

while engine is running.

Never run the engine under
load with this mixture of fuel
and oil.

Raw water cooling system

Close the seacock before removing the lid
of the water strainer. If necessary, clean
the raw water strainer.
Pour 1 litre (2 UK pt) of anti-freeze into the
water strainer and run the engine until the
anti-freeze has disappeared into the cool­ing system.
Take care that no anti-freeze is spilled into
the waterway (anti-freeze is poisonous).

Check the seal between the lid and hous­ing after cleaning and re-assembling the
strainer.
An improperly sealed lid will result in air
sucked in by the raw water pump which
again will result in overheating of the
engine.

Engine Lubricating Oil

Only use a recognised brand of oil for lubricating the engine.

Lube oils are differentiated according to their performance and
quality class. In common use are specifications named after
API (American Petroleum Institute) and CCMC (Committee of
Common Market Automobile Constructors).
Approved API Oils : CD, CE and CF4
Approved ACEA Oils : A3/B3, A3/B4

As the viscosity of lube oil is dependent on temperature, the oil
vicosity (SAE grade) should be selected according to the ambient
temperature when the the engine is started.
To avoid oil changes dictated by the seasons we advise one of
the following multi-grade oils.

- SAE 10W40 for temperatures of -25°C up to +30°C
(-13°F up to +86°F)

- SAE 15W40 for temperatures of -20°C up to +35°C
(-4°F up to +95°F)

For example: Vetus Marine Diesel Engine Oil 15W-40
Shell Nautilus Premium Inboard Oil 15W-40

Gearbox Lubricating Oil

Only use a recognised brand of oil for lubricating the gearbox.

Technodrive:

model TMC40 : 0.20 litres, Engine oil SAE 20/30
model TMC40 M / P : 0.20 litres, ATF*) (0.35 UK pt, 0.4 US pt)
model TMC60 : 0.80 litres, Engine oil SAE 20/30
model TMC60 E / P : 0.80 litres, ATF*) (1.4 UK pt, 1.7 US pt)
model TM345 A / H : 1.6 litres, Engine oil SAE 20W-40-CD
(2.8 UK pt, 3.4 US pt)

ZF Hurth:
model ZF10M : 0.35 litres, ATF*) (0.6 UK pt, 0.74 US pt)
model 12 : 1.1 litres, ATF*) (1.9 UK pt, 2.3 US pt)
model 15MA : 0.56 litres, ATF*) (1 UK pt, 1.2 US pt)
model 15V : 1.0 litres, ATF*) (1.8 UK pt, 2.1 US pt)

Operating media

Lubricating oil

Fuel Quality Grade

Use commercially available diesel fuel with less than 0.5% sulfer
content. If the sulfur content is higher than 0.5%, the intervals
between oil changes should be halved e.g. change oil every 250
hours. Don’t use fuel with more than 1% sulfur!

The following fuel specifications / standards are approved:

• CENEN590orDIN/EN590(underdevelopment)

• DIN51601(Feb.1986)

• BS2869(1988):A1andA2

• ASTMD975-88:D1andD2

• NATOCodeF-54andF75

The exhaust emission levels determined during certification by
the supervising authority are always based on the reference fuel
described by law.

Winter-grade fuel

Waxing may occur at low temperatures, clogging the fuel system
and reducing engine efficiency.
If the ambient temperature is less than 0°C (+32°F), winter-grade
fuel -suitable down to -15°C (+5°F) - should be used. This fuel is
usually available from filling stations well in advance of the cold
months. Diesel fuel containing additives (Super Diesel) is often
on sale as well, for use down to -20°C (-4°F).

Coolant fluid

The preparation and monitoring of coolant in inter-cooled engines
is especially important because corrosion, cavitation and freezing
can lead to engine damage. Use as coolant a mixture of a cool­ing system protective liquid (anti-freeze, ethylene glycol based)
and tap water.

In tropical climates, where anti-freeze availability may be limited,
use a corrosion inhibitor to protect the engine cooling system.

The concentration of the cooling system protective liquid in the
coolant should not fall below/exceed the following limits:

The protective liquid concentration must be maintained under all
circumstances. Therefor if coolant must be added always use the
same mixture of anti-freeze and tap water.

Water quality for coolant preparation

Use preferably tap water.

If an other available fresh water is used; the values given below
must not be exceeded.

Never use sea-water or brackish water.

Cooling system protective liquids must be disposed of
in accordance with environmental regulations.
