Protect the sea cock as follows:
With the motor stopped.
• Place the sea cock in a position that it
is just opening.
• Pour a small amount of non-toxic bi-
odegradable anti-freeze into the raw
water strainer.
• Close the sea cock as soon as it is
filled with anti-freeze.
Anti-freeze can be toxic. Take care that no
anti-freeze is spilled into the waterway
• Check the seal between the lid and hous-
ing after cleaning and re-assembling the
strainer.
An improperly sealed lid will result in air
sucked in by the raw water pump which again
will result in overheating of the engine
5 Fresh water cooling system
To avoid corrosion during winter storage the
cooling system must be filled with an anti-
freeze/water mixture (or a coolant).
For specifications see page 119.
N.B. Replacing the coolant is only necessary
if the coolant present in the cooling system
offers insufficient protection against temper-
atures below 0˚C (32˚F).
For coolant replacement see page 70.
