MAINTENANCE TASK. ZINC ANODE INSPECTION
In order to avoid the corrosion produced by galvanic currents, the engine 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 engine 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 engine and check for leaks at the anticorrosion zinc anode location. The pump
is operating if the seawater flows from the exhaust outlet.
6.7. 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 engine operation:
-
Waterlock (supplied as accessory) to prevent seawater from entering inside the
engine when it stops.
Minimum Capacity (l) 3,5
-
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.
Type 1 installation. When between water injection point of wet exhaust and waterline is
minimum 150 mm.
