Seawater system. Cleaning and
inhibiting
To prevent the build up of deposits and salt crystals
in the seawater system it must be flushed with fresh-
water. When the boat is laid up it must also be inhibit-
ed.
WARNING! Risk of water penetration. Clean-
ing and inhibiting the seawater system should
be carried out with the boat on land.
1. Open the seawater cock (reverse gear).
2. Detach hose (1) from the seawater pump and
connect a hose (2) 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 compo-
nents and hot surfaces.
IMPORTANT! The impeller will be damaged
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 (1).
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 dispos-
al site.
