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 equipment)
or other method before draining the engine. If
the water is not drained properly the boat may fill
with water and sink. Check that there are no
leaks before you leave the boat.
1. Engine with drive: 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 removed. 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 diame-
ter hose. Plug one end of the hose with a piece of dowel or
similar 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 (CAC) 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.
