Cold weather precautions
15 In cold weather when there is a risk of freezing,
it is important that the freshwater system’s coo-
lant has sufficient frost protection. The seawater
system must be drained.
Watch out for leakage into the boat. Drain as fol-
lows:
Idling the engine
If the engine is to remain unused for a long period of
time, the engine should be run warm, at least once
a month.
Using a boat trailer
Raise the drive to the maximum before loading on
the trailer. Also refer to pages 13-14 Trim instru-
ment, Power Trim. Before the boat is transported on
a trailer, the drive must always be secured in the ra-
ised position so that it cannot possibly drop down.
Boats which are to be stored on land between peri-
ods of operation have an impaired galvanic protec-
tion due to oxide formation on the zinc anodes.
Hence, before launching, the protective anodes on
the drive and shield should be cleaned with emery
cloth to remove any oxide.
Note! A steel brush or other steel tools may not be
used for cleaning as this will cause deterioration of
the galvanic protection.
WARNING! To avoid injury, always make
sure that the engine is switched off before
starting work on it. There are many moving
parts - pulleys, drive belts etc.
Disconnect the hose (2) from the seawater filter
and bend it down so that the water runs out. Re-
connect the hose. Drain the oil cooler and the af-
tercooler (4), and undo the cover on the seawa-
ter pump and allow the water to drain out. Drain
the oil cooler on the KAD42 via the hose (3) mar-
ked blue.
Reverse gear HS1A: Close the bottom cock and
undo the hose on the oil cooler port side.
WARNING! Do not forget to close the
cocks. Never leave the boat with open
cocks or hoses that are not connected.
There is a risk that the boat could sink.
