Cold weather precautions

To prevent freezing damage, the seawater system must be drained and
the freshwater system coolant must have sufficient antifreeze
protection. See chapter Maintenance "Cooling systems".
IMPORTANT! A poorly charged battery may burst as a result of
freezing.

Laying up

If the boat is not going to be used for some time but is being left in the
water, the engine must be run to operating temperature at least once
every 14 days. This prevents corrosion in the engine. If the boat will not
be used for more than two months then inhibiting should be carried out:
See chapter on Laying up/Launching.

Transporting on a trailer

Check local legislation for transporting boats on trailers, there are
differences between different countries' trailer laws. For boats with
SX-drive: Lift the drive to the highest position when the boat is put on
the trailer (the drive is stopped automatically at the highest position).
IMPORTANT! The engine must not be run with the SX-drive is in
the lift range. Before transporting the boat by trailer always secure
the drive in the lift position with a Trailer Kit (accessory) or similar,
so that it cannot drop down.
IMPORTANT! Boats with reverse gear/S-drive: Drain water out the
exhaust pipes to prevent water entering the engine when
transporting the boat by trailer.

Laying up on land

Where boats are kept laid up on land when not in use there is a lower
level of galvanic corrosion protection due to the oxidation on the
sacrificial anodes. Before launching the boat the sacrificial anodes on
the drive and shield must be cleaned with emery paper to remove any
oxidation.
IMPORTANT! Do not use a wire brush or other steel tools when
cleaning, as these may damage the galvanic protection.
