Maintenance task. Zinc anode inspection
In order to avoid the corrosion produced by galvanic currents, the genset is fitted with a zinc
anode located on the front lid of the coolant-seawater heat exchanger. Anticorrosion zinc anode
inspection and replacement:
1.
With the genset cooled, close the seacock, open the coolant drain plug and drain the coolant
into a suitable container.
2.
Remove the anticorrosion zinc anode (plug) from the heat exchanger.
3.
Use a wire brush to remove the loose corrosion on the anticorrosion zinc anode.
4.
Clean the threaded hole of the heat exchanger and coat the threads of anticorrosion zinc
anode. Install the anticorrosion zinc anode into the heat exchanger.
5.
Close the coolant drain plug and open the seacock. Refill the coolant circuit.
6.
Start the genset and check for leaks at the anticorrosion zinc anode location. The pump is
operating if the seawater flows from the exhaust outlet.

Inlet and Exhaust System
Exhaust circuit description
There are two possible installations of the exhaust system. You need to check the distance
between water injection point and waterline to decide which type of installation you need. This
information is specified in the following drawings.
The elements included in the drawing are essential for the correct genset operation:
-
Waterlock (supplied as accessory) to prevent seawater from entering inside the engine when
it stops.
To calculate the required collector capacity, we must follow the following formula:
-
Goose neck (supplied as accessory)
-
Siphon breaker (supplied as accessory)
–
needed in case there is less than 150 mm between
the water injection point of wet exhaust and the waterline, or if the point of injection is below
waterline.
