This manual has to be read in combination with the
standard users manual and installation manual for
WhisperPower generator sets that apply to marine
installations based on seawater cooling (inter-cooling) This
manual contains instructions for installation as well as for
operation.
WARNING

WARNING!
Before working (installation) on the system
read the section safety instructions in the
user’s manual
1.2 KEEL COOLING
When using a marine sea water cooling system, seawater
is pumped by an impeller pump through a heat exchanger
and dumped overboard via the exhaust. The heat
exchanger unit is normally mounted on the engine. When
the cooler is part of the construction of the ship, we talk
about “keel cooling”. This cooler can be a section of the
keel or a ballast water tank. Sometimes one uses pipes
welded along the bottom, or a special designed cooler to
be mounted in the bottom. A specially designed cooler that
is often used in the hull of steel ships is called a “boxcooler” and is available as a WhisperPower installation kit.
Coolers to be mounted in the hull of wooden boats and
boats made of fibreglass are available on the market but
rarely used. WhisperPower does not supply these coolers.
This manual refers to the box-cooler units, which are
supplied by WhisperPower. Similar instructions are valid
for other types of keel cooling.

1.3 DIFFERENT COOLING AND EXHAUST
A keel-cooling system and as a consequence the dry
exhaust system is completely different from standard “wet”
or “intercooling” marine systems. Standard marine
generators are cooled by seawater that nowhere exceeds
30° Celsius and is seldom warmer than 20° Celsius in the
northern territories. Cold seawater is pumped through the
alternator, through a heat exchanger and is injected in the
exhaust. The exhaust gasses are therefore cooled and
rubber exhaust hose can be used.
With most WhisperPower generator sets both the
alternator and the engine are water cooled. Therefore,
when applying keel-cooling, two cooling systems are
necessary: one for the engine and one for the alternator.
Exception: the alternators of the M-SQ25, M-SQ12 Three
Phase and M-SQ16 Three Phase are air cooled. Therefore
these generator-sets need one cooling system, for the
engine only.
The exhaust is of the dry type and includes a stainless
flexible bellow and high quality metal mufflers.
Never use rubber exhaust hose, neither
fibreglass nor plastic exhaust parts in a dry
exhaust system.
1.3.1 Why two coolers:
The optimum engine operating temperature is 87° up to
95° Celsius. The cooler cools the temperature of the
cooling liquid in the engine only 5° to 12° down. The
returning “cold” coolant therefore has a minimum
temperature of 75° Celsius. The alternator should be kept
as cool as possible. In practice an alternator starts getting
less efficient above 40° Celsius. Because of the
divergence in the working temperature of engine and
alternator it will be clear that it is not possible to combine
the cooling of the engine and alternator in one cooler
system.

2 INSTALLATION
2.1 INSTALLATION OF THE COOLERS
2.1.1 General
Different from marine inter-cooling systems, marine keelcooling systems use an open -non pressurised-system.
Therefore the 12 mm overflow pillar on the expansion tank
should stay open. A piece of hose can be used to drain
redundant liquid that is thrown out because of the
expansion of the liquid in the system. When open the
expansion tanks can easily release air that is ventilated by
the different connections.
Figure 2: The exhaust manifold to be ventilated into the
expansion tank
It is necessary to ventilate the exhaust manifold. The
exhaust manifold has a cap that let the 8 mm connection
open to ventilate the manifold. There is a 8 mm inner
diameter high temperature resistant synthetic hose in the
delivery to connect the hose connection on the side of the
filling cap of the manifold with the expansion tank. This
hose can go down first through a hole one has to drill in
the lower green part of the soundshield canopy and than
up again to the expansion tank. (refer to figure 2).
2.1.2 Location of the box-coolers
Box-coolers can be installed in the bottom or in the side of
a steel vessel. A hole is made in the hull and the box
cooler is welded in this hole. When the box is on the
bottom a connection has to be made from the top of the
cooler to the side of the ship to release the air and
optimise the flow of water through the cooler. A 90° elbow
is in the box cooler kit. (refer to figure 3).
2.1.3 Ventilation and expansion tank
Special attention should be spent to the ventilation of the
systems. Each installation system is standard supplied
with an expansion tank for the coolant, that is also used to
release air bubbles and makes it possible to add coolant to
the system in an easy way. This expansion tank should be
at the highest point of the system.

INSTALLATION
6 September 2010 / WhisperPower keel cooling / EN
Most cooling problems originate from air traps
blocking the circulation of the engine coolant.
It is prescribed to have the expansion tank of
the engine cooling system connected to the
outlet connection of the cooler unit.
Figure 4:
7 litres optional expansion tank with low level alarm.
As a keel-cooling system mostly contains much coolant a
large seven litres expansion tank with low level alarm is
recommended for the engine cooling system (refer to fig. 4
and fig. 5, detail A)
The alternator system can be ventilated on the box cooler
and a small expansion tank will be sufficient (refer to figure
5 detail B).
2.1.4 M-SC3.5 oil cooler
The M-SC3.5 is different from all other models because
the engine is cooled by oil and not by cooling liquid.
There are 2 ways to design the cooling:
1) Using separate box coolers; one for the oil cooling
and one for the generator coolant.
The engine oil cooling system for the M-SC3.5 does not
need an expansion tank as the system is ventilated in the
engine. The piping of the oil cooling system should be
according to the dimensions listed in the kits and the total
length should not exceed 6 meters to prevent an excess of
expanding oil and a too high backpressure.
As the cooler box will be positioned in the bottom or side
and therefore lower than the engine, no additional valves
are necessary, however a valve could be fitted by the
factory as standard for radiator application and it is
recommended to be removed. This valve will be necessary
when the cooler is mounted higher than the engine (refer
to figure 6).
2) Using a heat exchanger to cool the oil indirectly. The
coolant through the heat exchanger is the same as to cool
the alternator.
This is the easiest way from the point of installation as one
only need one box cooler, but the cooler must have the
extra capacity to cool down the coolant for both jobs.
When the capacity is too little the alternator temperature
will be high and this could reduce output power and output
voltage.

Figure 6:
The pressure valve in the return oil line pre vents the engine
from overflowing as a result of siphoning if the cooler is
situated above the engine.

EN / WhisperPower keel cooling / September 2010 7
When it is not possible to drain the oil from the
box cooler, one should pump out the engine
sump as good as possible and increase the oil
change intervals to every 50 running hours.
2.1.5 Further recommendations
As the (indirect) cooling by outboard water is very efficient,
keel cooling is without problems. Most important is to
avoid air traps in the piping and additional ventilation of the
pipes can be necessary when bents are not to be avoided
(refer to figure 7).
Figure 7: Ventilating an air trap
2.1.6 Cooling capacity
Using a box cooler the outboard water will bring the
temperature of the engine coolant only 10 up to 15°
Celsius down. The difference between 90° “in” and 80°
“out” (ΔT) is hardly noticeable. So do not conclude too fast
that the system is not working well. When using another
system than the recommended box-coolers one has to be
certain that the cooling capacity is enough. Paint and
fouling on the hull or on pipes along the bottom can reduce
the cooling capacity of the system.
2.2 DRY EXHAUST SYSTEM
2.2.1 General remarks
A dry exhaust muffler system should be as effective in
silencing the exhaust as a wet marine exhaust system
when applying the right mufflers. However noise could be
generated by vibrations in the mufflers and be transferred
to the structure of the ship. Tacit factors like the length of
specific pipe sections could be important. It is very difficult
to take these factors into account.
A dry exhaust system on a boat can generate
noise problems caused by resonance of the
pipes and mufflers.
Figure 8: Dry exhaust system
The standard WhisperPower exhaust kit contains the
materials to perform a professional installation. In the kit is
a stainless steel flexible bellow (hose) to prevent vibrations
to be transferred. Also rubbers are supplied to mount the
mufflers flexible. The insulation blanket for the flexible
bellow and the mufflers are also very effective in damping
vibrations. Still it could be that additional measures has to
be taken like an extra clamp in a vibrating section of pipe,
insulation blankets on other parts of the system and
possibly even additional mufflers.
Special care has to be given to avoid water
from outside to get into the system. When the
exhaust is led through the deck or through the
roof of the wheelhouse, measures has to be
taken to prevent rainwater to enter the
system. Special rain caps are available as an
option.
Figure 9. Ways to prevent water to get in
A negative feature of a dry exhaust system is the heat
radiated by its components.
Measures are to be taken to overcome the heat problem:
The exhaust bent to bring the exhaust out of the canopy is
cooled by water. Insulation blankets are included in the
exhaust kit to insulate the flexible bellow and the mufflers.
When a dry exhaust has its outlet on the deck or the roof,
all the pipes inside the ship that can be touched by people,
has to be insulated.
Page 8
INSTALLATION
8 September 2010 / WhisperPower keel cooling / EN
The exhaust pipes will be very hot and all
accessible pipes are dangerous to people
when not insulated.
There are companies that are specialised in insulating hot
pipes and fancy systems are available to make it good
looking. However it is also possible to do it yourself by
winding fibreglass around the pipes and seal it with
aluminium tape.
2.2.2 The standard dry exhaust system
The standard exhaust system contains:
On the generator set:
• An insulated exhaust bent
In the exhaust installation kit:
• A stainless steel shielded flexible bellow.
• One resonance muffler
• One absorption muffler
• Clamps and rubbers to mount the system flexible
• Fittings, bents and pipes to make the different
connections
• Blankets for thermal and sound insulation.
The mufflers are high quality industrial mufflers that are
much more effective, robust and durable than mufflers
made for automotive use.
2.2.3 Installation of the exhaust
Before determining the location of the generator set one
has to consider how to get away with the exhaust. The
outlet should blow the fumes away from the doors to avoid
a nasty smell. In wind still conditions a light smell of
exhaust fumes around then vessel will not be avoidable.
To bring the exhaust to the top of the roof of the
wheelhouse gives the best results on noise and smell.
However, when the pipes go through the interior of the
vessel, they should be insulated and around the hole in
the roof should be a collar to prevent rainwater to leak in.
Both mufflers could be on the roof or one of them or both
could be below the deck.
In general it is better to have the mufflers wide apart: the
resonance muffler close to the generator and the
absorption muffler on the end of the line. A short pipe
(30cm / 1 ft.) should be on the far end after the absorption
muffler. The absorption muffler has no flow direction and
could be mounted both ways. The resonance muffler
should be mounted in the gas flow according to the
indication on the muffler itself.
The resonance muffler should be fitted
according to direction of the gas flow
indicated.
In the kit are clamps to mount the exhaust pipes to steel
bars. These bars should be mounted to the structure of the
ship. It is recommend to use rubber mountings only when
there is risk to transfer vibrations to the structure. However
take care that the heat conducted through the brackets will
not affect the rubber.
Refer to figure 10 how to mount the rubber in a safe way.
When any doubt an extra safe guard could be constructed
from steel wire or chain.
Figure 10. Mounting bracket in rubber with safe guard
Due to the effects of inertia when a boat is
heavily moving in rough water not all bars
should be in rubber but bolded or welded to
the superstructure of the vessel.
2.3 CONNECTIONS
The generating set comes with all supply lines and output
cable (i.e. electric cables, coolant connections, exhaust,
fuel lines etc.) already connected to the engine and
alternator. The supply lines are fed through the capsule’s
base. The connections are marked as shown in figures 10
till 17.
All electrical connections, cable types and sizes must
comply with the appropriate national regulations. Supplied
cables are rated for ambient temperatures up to 70°C. If
the cables are required to meet higher temperature
requirements, they must be run through conduits.
