Seawater system. Draining
To prevent freezing damage the seawater system
must be drained in cold weather where there is a risk
of frost.
WARNING! If the boat is left in the water, the
seawater intake to the engine must be turned
off with a seawater cock (non-standard equip-
ment) or other method before draining the en-
gine. If the water is not drained properly the
boat may fill with water and sink. Pump out the
boat and ensure that there are no leaks before
you leave the boat.
1. Engine with drive DP: Remove the seawater
hose from the shield and close the intake with a
plug (1)* tightened with a hose clamp. Water will
flow in immediately the seawater hose is re-
moved. Have tools, plug and hose clamp ready.
Bend seawater hose down so the water runs out.
WARNING! To prevent freezing of the water re-
maining in the drive water galleries, the drive
must be completely trimmed down in the water.
*
Make this plug from a 100 mm long piece of 30 mm diameter
hose. Plug one end of the hose with a piece of dowel or simi-
lar and hold the dowel in place with a hose clamp.
Engine with reverse gear Close the sea cock.
Drain oil cooler by opening the plug (2). Discon-
nect hose (3) and bend down so that the water
runs out. Disconnect hose (4) by the sea cock
and empty it of water.
2. Detach the hose (5) and drain water out of heat
exchanger. Drain charge air cooler by opening the
plug (6) and oil cooler by opening plug on the blue
marked hose (7).
3. Remove the cover from the seawater pump and
let the water run out.
4. Connect and tighten all hoses. Reinstall the cover
on the seawater pump and the cover plate on the
seawater filter.
When laying up the boat, remove the impeller
from the seawater pump and store it in a cool
place in a plastic bag. Reinstall the impeller when
bringing the boat out of storage.
