Cooling circuit - seawater
I
Attention ! :
When the craft is in the water, there is a risk of water penetrating the craft when working on the seawater
circuit. Water can penetrate the craft via circuit components found below the waterline. Close the seawater intake valve (if
fi
tted) or prevent water discharge before working on this circuit!
Cleaning the seawater circuit is essential to preventing the formation of deposits and salt crystals. The presence of a
seawater
fi
lter between the pump and the water intake is mandatory. Check and clean the
fi
lter regularly.
