Drain off all the coolant by opening the two drain plugs, one in the heat exchanger and the
other in the cylinder block.

Refill to the hole in the tank cap with coolant.
Maintenance task. Seawater filter inspection
It is important to install a seawater filter (supplied as accessory) between seawater cock and
the seawater pump to avoid that any impurity might clog the seawater circuit or seawater pump.
To clean this filter:
1.
Loosen the wing nut.
2.
Remove the filtering component and clean it.
3.
Fit it again taking care that the cover is well seated on the o-ring.
4.
Start the engine to check seawater leakages.
Maintenance task. Seawater pump impeller inspection
Seawater pump impeller is neoprene and cannot rotate dried. If operated without water, the
impeller can be broken. It is important therefore that a spare impeller is always available. Impeller
inspection and replacement procedure:
1.
Close the seawater cock.
2.
Remove the seawater pump cover plate.
3.
Remove the impeller from the shaft.
4.
Clean the housing.
5.
Inspect the impeller for damaged,
cranked, broken, missing or flattened
vanes. The impeller vanes should be
straight and flexible.
6.
If it is damaged replace with a new one.
7.
Lubricate the impeller with soapy water
before installation.
8.
Install the impeller. During installation push and rotate the impeller in the same direction as
the engine rotation until it is thoroughly seated in the impeller housing.
9.
Inspect the cover plate and gasket for corrosion and/or damage. Replace components as
necessary.
10.
Lubricate the oil ring with silicon grease and attach the gasket and cover plate to the seawater
pump housing.
11.
Open the seacock.
12.
