Check the antifreeze in the freshwater system after the
engine has stopped if there is a risk of freezing. See un-
der the heading. “Coolant” on page 16.
Drain the water from the seawater system as described
below. Check that all the water has drained out.
Check batteries in accordance with instructions on page
62. A poorly charged battery can burst if it freezes.
Draining coolant
Before draining the coolant, the engine should be
stopped, the filler cap unscrewed and the boat’s sea
cock closed. Then open the drain cocks or remove the
drain plugs of the engine’s freshwater and seawater
systems, see Figures.
Check that all the water runs out. There may be depos-
its by the cock/plug which must be removed. Otherwise
there is a risk that water may remain in the system and
cause serious damage.
Check whether the installation has any more cocks or
plugs on the cooling water and exhaust pipes’ lowest
points.
Remove the cover from the seawater pump and the
cover on any extra pump.
Close the cocks, fit the plugs and put the cover on the
seawater pump (and any extra pump fitted).
Pump out the boat if required. Ensure that there are
no leaks before you leave the boat.
See the instructions on page 55 for topping up the cool-
ant.
