Laying up on land
Where boats are kept laid up on land when not in use, for
example, trailer boats, there is a lower level of galvanic
corrosion protection due to oxidation on the sacrificial an-
odes. 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.
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 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 automatically reset
when trimming down. NOTE! Check local legislation for
transporting boats on trailers, there are differences be-
tween 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.
Boats with reverse gear: Drain water out the exhaust
pipes to prevent water entering the engine when trans-
porting the boat by trailer.
Stopping the engine
