Marine diesel engines. Operator’s manual
9.
Inspect the cover plate and gasket for corrosion and/or damage. Replace components as
necessary.
10.
Lubricate the gasket with silicon grease and attach the gasket and cover plate to the
seawater pump housing.
11.
Open the seacock.
12.
Start the genset and check for leaks.
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 engine 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:
C = collector capacity (L)
D = Inside diameter of the tube (mm)
L = Tube length (mm)
-
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.
