Cold weather precautions

To prevent freezing damage, the seawater system must
be drained and the freshwater system coolant must have
sufficient antifreeze protection. Refer to the cooling system
section in chapter "Maintenance".
IMPORTANT! A poorly charged battery may burst as
a result of freezing.
Transporting on a trailer
Before pulling boats with a drive on to a trailer, trim the
drive out to "Lift range" (maximum lift). An automatic stop
will cut off the current to the hydraulic pump when the
drive has reached its max. lift point. The stop is automati-
cally reset when trimming down. NOTE! Check local legis-
lation for transporting boats on trailers, there are differenc-
es between different countries' trailer laws. It is possible to
trim the drive without starting the engine.
IMPORTANT! The engine must not be run with the
drive 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 can-
not drop down.
IMPORTANT! Boats with reverse gear: Drain water
out the exhaust system to prevent water entering the
engine when transporting the boat by trailer.
Laying up on land/Launching
IMPORTANT! If the boat (engine) submerges sig-
nificantly below the static waterline (A) when it is laid
up or launched there is a risk of water entering the
A
engine through the exhaust system.
Where boats are kept laid up on land when not in use,
there is a lower level of galvanic corrosion protection due
to 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 gal-
vanic protection.
