4.15 BOW THRUSTER (OPTIONAL)
Your boat may come equipped with the bow thruster which helps you better manoeuvre
at lower speeds. The bow thruster placed below the waterline opens at both sides of the
boat, near the bow. The thruster takes suction from one side and throws it out at the
other side of the boat, thus moving the boat in the opposite direction.
To activate the thruster, the thruster battery main switch, located at the helm, must be
turned on first. This switch connects the thruster battery with the thruster motor, and
should only be turned on when the thruster is to be used. A joystick controls it, see the
figure given below.
The maximum continuous usage time of the electrical thruster is approximately 2-3
minutes. The electromotor has a built-in thermal cut-off switch that shuts off the
electromotor if it is overheating and re-engage it when it has cooled down. This should
be considered when planning your manoeuvring.
The bow thruster motor is placed below the water line in a bow thruster room, found
below the inspection cover on the bow cockpit deck. The thruster room has drainage to
the keel to avoid flooding in case of leaks. The bow thruster room should be checked for
signs of leakage every season. There is also a 240 Amp fuse installed next to the motor.

Do not touch the bow thruster fuse, motor, switch, cables or battery if the electric main
switch is switched on. Even if the switch is off, be very careful and consult professional service
staff if in any doubts. There is a risk of high electric currents which may cause an electric
shock, which may be fatal.
