9.1. Launching the boat / making adjustments
CAUTION
- Ensure that the raw-water cooling intake valve is open and that water is coming out of the exhaust.
A quick check that the propeller is securely fixed should be carried out before each launch.
A poorly working propeller can be a source of vibration.
Regularly check the condition of the zinc anodes and ensure that they are the correct anodes for the
environment (fresh water or sea water). Change the anodes every year.
The purpose of an anode is to equalize the electrical potential between the aluminium and other metals
(stainless steel, bronze, etc.) The average life expectancy of an anode is 1 to 2 years.
These anodes are made of zinc. Anodes made from magnesium must absolutely not be used. Systems using
impressed current for cathodic protection are to be avoided.
If the anodes have not been changed, you must check:
-
That they have not been painted,
-
That they are securely fixed and are in contact with metallic parts,
-
That they are made from zinc.
CAUTION
Under sail and with the engines switched off, the raw water intake seacock must be closed at speeds
in excess of 8 kts, and this brought to the attention of the helmsman.
