1 Guided tour of the Super Maramu 2000
1.1 Electric power from the AMEL point of view
Most of the electrical equipment in board of the Super Maramu 2000 works with in 24 V DC.
This energy is stored in batteries that need to be charged regularly. Ideally, charging
should be done promptly produce when needed.
When the boat is in a harbour, connected to the shore power, batteries are charged
automatically with the 30 A charger (optional) which is less greedy than the 100 A.
When the boat sails, a lot of 24 V equipment (automatic pilot, electronics, rig and sail furling
system, winches, refrigerators, lightning, …) work with the batteries’ energy. If we don’t pay
attention, they will be quickly discharged. Thus the generator should be switched on
regularly to charge the 24 V batteries with the 100 A charger. If it is possible, schedule not a
daily long time, but 3 shorter periods of 1 and a half to 2 hours. The next chart shows a
solution, but your own experience can improve it.

During the night, automatic

At dinner time, for the same
reasons as previously, and to
have good batteries for the
night.
At the harbour : 30 A charger
In the open sea : 100 A charger
5 to 6 hours seem to be reasonable, regarding to the needs of the crew.
When the boat is at anchorage, 24 V uses are less, and 3 to 4 hours of generator’s work
should be enough.
Batteries wear out, not due to their age, but according to their number of cycles of Charge /
Discharge. That is why batteries of an occupied boat, but most of the time connected to
shore power, will last longer (4 years max.) than batteries on a boat who sails or at the
anchorage most of the time. In that case, lifetime of the batteries will probably not exceed 18
months.
Batteries usually fail because they are not charged enough.

1.1.1 Power generator
DANGER ! Read carefully the generator’s manual
before use. It contains warnings concerning your own
safety while operating and doing maintenance.
Any maintenance work on mechanical or electrical parts
of the generator should be done by skilled workers,
using appropriate tools and protections.
The power generator can be started from two control knobs : one in the galley and one on
the control panel on the generator itself.
The generator is located in the engine room portside. It uses diesel fuel.
The diesel fuel comes from the RACOR prefilter / water strainer, enters the electric priming
pump and the engine's filter, and then feeds the injection pump. The overflow returns straight
to the fuel tank. To bleed the fuel circuit on the generator, refer to generator owner's manual.
It is important to start the generator without load, meaning every 220V equipment is
switched off. Check the seacock for seawater intake (see 1.4.2). Check also for water
discharge from the hull exhaust outlet when the generator is running. outlet.
Once the generator has been running for more than 1 hour at heavy load, before
stopping it, let it run 1 minute without load to let it cool down.
There are several circuit breakers and fault breakers on the generator control panel in the
engine room. Refer to generator's manual.
The seawater cooling circuit is fitted with an anti-siphon system to prevent seawater from
returning into the engine.
Here are the main specifications of the ONAN MDKAV 7kW generator.
For further information, refer to generator's manual.

About the exhaust circuit of the generator :
It is fitted with a muffler were the exhaust gas is mixed with seawater and therefore cooled
down. When the generator is running, make sure that seawater flows out of the exhaust
discharge outlet on the hull.

1.1.3 Ground circuit and protection against electrolysis
All the equipment in contact with water (pumps, engines, pipes, transmission, propeller,
toilets, …) are connected together to make a circuit, isolated from the other wires but linked
to the zinc anodes of the rudder.
This installation (green / yellow wire) represents a protection against the electrolysis :
anodes break up, but not the item being protected.
Warning : inspect anodes every 6 months.
Change anodes every year, maybe more often. Electrolysis depends on the environment of
the boat, ands especially if there is a metal boat close-by.
The Super Maramu 2000 has got in standard 2 ground plates on the rudder, used by the
SSB system.
If the boat hasn’t got any SSB, these plates are connected to the zinc anodes.
When setting up a SSB, disconnect ground plates of the anodes (behind the chart table).
When a new metallic material in contact with water is installed :
-be sure the alimentation wires (positive and negative) are isolated,
-link the metallic part to the ground circuit.
Maybe after having set a new electrical appliance, the mass circuit isn’t perfectly insulated
anymore from the 24 V positive or negative. Some electrical leaks and damages on the
appliances, equipment, seacocks or components of the boat linked to the mass circuit can
appear.
A leak detector is installed on the companion way’s bulkhead. You can search for an
electrical leak on the inside electrical circuit of the boat (but not on the electrical circuit of the
masts).
To use it, push the switch to “Masse +” position : if the light is on, it means that the mass
circuit is linked to the positive circuit of the boat; if nothing is on, push the switch in the
“Masse –“ position : if the light is on, it means that the mass circuit is linked to the negative
circuit of the boat.
In the case of a light on, the leak must be find and suppressed.
The leaks must be looked for at least twice a year, or more if necessary : if you see that your
anodes break up fast, if you have some metallic boats as neighbours, if you set a new
electrical appliance (computer, antenna, pump, radio, …) or to confirm electrolysis
symptoms.

1.2 Main engine
1.2.1 Engine
DANGER ! User's manuals for the main engine and the
hydraulic gearbox content safety warnings that must be
respected. Refer to these manuals before use.
Any mechanic or electrical work should be done by
skilled staff, using appropriate tools and equipment.
Warning 1 : some drops of oil could be seen in the bilge below the engine. One must take
this for granted. This is not a symptom of a faulty engine.
Warning 2 : you must run the main engine everyday of sailing for 15 or 20 minutes (in 1 or 2
times) to drain the exhaust circuit (the waves fill in it).
Diesel fuel runs from the RACOR pre-filter/water-strainer to the engine's fuel filter and then
to the injection pump that feeds the injectors. Afterwards, the fuel overflow returns straight
into the fuel tank (see 1.4.1). On the injection pump, a red handle makes it possible to stop
the engine manually, in case the electrical stop doesn't work.

When the engine has been running for a long time at high load, let it idle several minutes
before stopping to cool it down and to allow the turbocharger to slow down.
The seawater cooling circuit is fitted with an anti-siphon system to prevent seawater from
returning into the engine.
The transmission (to shift from forward to reverse) is hydraulic-powered. Refer to
manufacturer's manual for maintenance and further information.
While sailing, the hydraulic brake prevents the propeller shaft from turning and makes it
possible for the propeller to feather.
A rubber coupling dampens the shock of shifting the transmission.
