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.
3. Clean it.
4. Fit it again taking care that the cover is
well seated on the o-ring.
5. Start the genset 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.
If it is damaged replace with a new one.

6. Lubricate the impeller with soapy water before installation.
7. 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.
8. Inspect the cover plate and gasket for corrosion and/or damage. Replace components as
necessary.
9. Lubricate the gasket with silicon grease and attach the gasket and cover plate to the
seawater pump housing.
10. Open the seacock.
