marking for maximum and minimum levels.
When necessary, fill up with fresh water or corrosion inhibitive anti freeze mixture. When there is a
danger of frost it is important to ensure that the fresh water system is filled with anti freeze.
Alternatively, the system can be drained. For draining the sea water system see under

tensioned, it should be possible to push the belt down about 5 mm midway between the pulleys
within your thumb.
To tension the belt, first loosen the mounting nut for the alternator. Worn or cracked belts should be
replaced.

The electrolyte level in the battery should be 5-10mm above the cell plates. Fill up with distilled water
when necessary.

Exercise great care when filling as the gas formed in the battery is explosive and the acid
caustic.
