SXP80/185T & SXP100/185T External stern thruster assembly
1.0.2 - 2016
Important user precautions
Warning
:
Tampering with the Ignition Protected stern thruster assembly or any attempt to disassemble anything on this thruster
assembly inside the boat can cause an explosion with very serious consequences.
If there is a problem with your Ignition Protected stern thruster, please contact your dealer.
Danger: NEVER Disassemble any part of the Ignition Protected stern thruster assembly
• Ensure that you know the location of the main battery switch that
disconnects the thruster from all power sources (batteries) so that
the thruster can be turned off in case of a malfunction.
• Always turn the main power switch off before touching any part of
the thruster, as an incidental start while touching moving parts can
cause serious injuries.
• Always turn the control device off when the thruster is not in use.
• The maximum continues usage time of the electrical thruster is
approximately 3 minutes. The electromotor has a built in thermal
cut-off switch that will shut off the electromotor if it is overheating
and re-engage it when it has cooled down some. This should be
considered when planning your maneuvering.
• This also means that the thruster will limit its total running time per
time period so that you can not count on the thruster to hold you
in a current and side wind for extensive time periods. Depending
on the surrounding temperatures etc. the thruster will be able to
run approximately 10 % of the time.
• Never use a thruster close to somebody in the water, as the
thruster will draw objects close by into the tunnel and contact with
the rotating propellers will cause serious injuries.
• With the boat on land, only run the thruster for a fraction of a
second, as without resistance it will accelerate very fast to a
damaging rpm. Also, while the thruster is in air, make sure that the
propellers have come to a complete stop before performing a
directions change of the thruster, as it might cause damage to the
thruster.
• If the thruster stops giving thrust while the electromotor is running,
chances are that there is a problem in the drive-system. You must
then immediately stop trying to run it, and turn it off, as running the
electromotor for more than a few seconds without resistance from
the propeller, can cause serious damage to the electromotor.
• When leaving the boat always turn off the main power switch for
the thruster.
• We advice to always keep the main engine(s) running while using a
thruster. This will keep the batteries in a good charge condition. This
will also give better performance to the thruster, as a higher voltage at
the thruster results in a higher torque (power) in the electromotor.
• Please note that the performance of a thruster strongly depends on
the voltage available at the electromotor. This voltage will decrease
by time because aging batteries have a reduction of capacity. By
installing new batteries the effect of the thruster should be back at
the original level.
• Make sure that only one control is used at the same time, if two
panels are operated in opposite directions at the same time the
thruster will not run at all. If they are operated in the same direction
the thruster will run in this direction.
• If the thruster is not performing or functioning as usual, the cause for
this must be found and corrected as soon as possible so to avoid
causing any other or further damage to the equipment. You must
also turn off the main battery switch immediately in case the
problem is of electric origin.
• Never store anything (e.g. equipment, sails, ropes etc.) in the
same compartment as the thruster. When the thruster runs for
a longer period it will get hot and will cause damage.
• It is the owner/captain/other responsible party full responsibility to as-
sess the risk of any unexpected incidents on the vessel. If the thruster
stops giving thrust for some reason while maneuvering you must have
considered a plan on how to avoid damage to persons or other ob
jects.
