Seawater system. Cleaning and inhibiting
To prevent the build up of deposits and salt crystals in
the seawater system it must be flushed with freshwa-
ter. When the boat is laid up it must also be inhibited.
WARNING!
Risk of water penetration. Cleaning
and inhibiting the seawater system should be
carried out with the boat on land.
1. Open the seawater cock on drive-unit.
2. Detach hose from the seawater pump and connect
a hose (1) which reaches to a bucket filled with
fresh water. Take care of filling.
3.
Check that there is nothing that will get splashed
behind the exhaust outlet.
WARNING!
Approaching a running
engine is dangerous. Watch out for rotating
components and hot surfaces.
IMPORTANT!
The impeller will be dam-
aged if it runs dry.
4.
Set the gear control lever in the neutral position.
Check that nobody is near the propellers. Start the
engine. Let it run at fast idle a few minutes. Stop
the engine.
5.
For inhibiting fill a bucket with antifreeze mixture
(50/50 freshwater and antifreeze). Secure a con-
tainer by the exhaust outlet. Repeat step 4.
6. Connect seawater hose.
7. The system is now inhibited. The antifreeze mix-
ture should be left in the system while the boat is
laid up. Drain the mixture just before the boat is
launched. Reuse the antifreeze mixture next sea-
son or deposit it at a properly designated disposal
site.
