Sea water system, cleaning and conserving

The sea water system must be flushed with fresh water, to prevent deposits and salt crystals from building up inside it. It must also be conserved when the boat is laid up.

WARNING! Risk of water entry. Cleaning and conservation of the sea water system must always be done when the boat has been drawn up on land.

1. Disconnect the hose from the sea water pump and install a hose which goes to a bucket filled with fresh water. Check that there is nothing beside the exhaust outlet that could be splashed.

2. Fill up carefully.

3.

WARNING! Coming close to a running engine is a safety risk. Watch out for rotating components and hot surfaces.

IMPORTANT! The impeller will be damaged if it is run dry.

Put the gear selector in neutral. Check that there is nobody close to the propellers. Start the engine. Let it run at fast idle for a few minutes. Stop the engine.

4. Fill a bucket with a mixture of 40% glycol and 60% percent fresh water, to conserve the system.

Put a suitable vessel under the exhaust outlet.

Repeat stage 3.

5. Put the sea water hose back.

6. The system has now been conserved. The glycol mixture should remain in the system during storage.

Drain the mixture before the boat is launched. Hand the mixture to a recycling depot.
