Frost precautions
As protection against corrosion and to secure the cooling water freezing temperature to min. minus 15° Celsius as per
IMO/SOLAS requirement or lower if required from climate conditions, It is recommended to use a mixture of
min. 30%
antifreeze liquid and 70% water
and
max. 50% antifreeze and 50% water.
However
please also note when doing service on lifeboats
that the mix of water and antifreeze can get aggressive and
start corrosion. If corrosion is found in the cooling system it can be caused by one of two conditions:
1. The anti corrosion additives in the anti freezing liquid are exhausted and have evaporated.
2. Oxidation due to incoming air causing an acid which is lowering the PH value.
Therefore and also to keep the anti freezing properties it is recommended to
change the cooling water and antifreeze
every 3 years min.
Please also note the details provided by your supplier of antifreeze liquid normally stated on the can.
Electrical System
The engine is equipped with a 12 volt electrical system consisting of a starter motor and an alternator, the max. charging
current of which is 50 Amp.
Electrical wiring diagram for the engine with control and instrument panels is shown later in this instruction.
The battery must never be isolated from the alternator, when the engine is running.
Warning! It is not allowed to connect additional equipment to the wiring system on the engine. Possible additional
equipment has to be connected directly to the terminals of the battery.
NOTE!
The starter must not be operated for more than 10 sec. If further operation is necessary, a pause of at least half a minute
before starting attempt is repeated.
Marine Gear
The engine is equipped with a reverse-reduction gear. The standard reduction is 2.94:1 for
AHEAD and 1.95:1 for REVERSE (but also available as 2.63:1 for special purposes).
The marine gear will need no other attendance than regular change of oil. This to be carried
out after 25 hours of operation, and then every 250 hours or once a year.
Oil quality: "Automatic Transmission Fluid” (ATF).
The oil change is carried out by means of the lubricating oil bilge pump fitted on the engine.
The oil should be warm when draining.
Refill new oil to the quantity of 0.5 liters through the dipstick hole.
Check oil level on the dipstick.
Don’t forget to close the cock before starting up.
