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.
A
Cleaning the seawater fi lter
The seawater fi lter is an optional component. These
instructions are given as an example only.
• Check the condition of the seawater fi lter with the engine
stopped. If deposits have formed, remove the fi lter in
order to clean it.
• Remove the cover and then the fi ltering part A. Remove
all the debris on the housing.
• Rinse the fi lter and the housing with fresh water and
check the condition of the seal, then re-install all the
components and check there are no water and/or air
leaks in the circuit when operational.
Draining the seawater circuit
• Close the seawater intake valve.
• Place a pail under the drain caps A & B
• Remove the caps A & B
• Let the water fl ow in the pails
• Refi t the caps
• Drain also the exhaust circuit. A small amount of water
may remain in the bottom of the waterlock box.
