Stern Thruster Installation Considerations and Precautions
EN
• If you are installing the Side-Power in a small room/ compartment, it
should be ventilated to allow cooling of the electromotor.
• If the height of the room you are installing the Side-Power is limited, it
can be installed horizontally or at any angle in-between.
- If the electromotor is positioned more than 30º off vertical, it must be
supported separately.
- The electromotor must be handled with care. Do not lift it by internal
connections/ main terminals or bed placed down on the driveshaft.
- Beware of keeping installation within advised measurements. No
part of the propeller or gear house must be outside the tunnel.
• Do not install the thruster in a position where you need to cut a stiff ener/
stringer/ support for the hull integrity without checking with the boat
builder this can be done safely.
• The electromotor and solenoid system (excluding SX & EX series) are
not considered waterproof and will be damaged if exposed to water (rust
and corrosion). The thrusters installation compartment must be kept dry
at all times. If required a separate compartment must be created.
- Ensure the propeller/ rudder shaft or other moving parts with a high
possibility of leakage is not in the electromotor compartment.
- If needed We advise installing a self-activating bilge-pump, preferably
with an alarm system, in the stern thruster compartment. (NB: If you are
not confi dent that you sealed this compartment, this pump is required.
• We advise painting the gear house and propellers with antifouling.
(NB:
Do not paint the anodes, sealings or propeller shafts)
• Do not fi nish the inside of the tunnel with a layer of gelcoat/ topcoat or
similar. There is only room for a thin coat of primer and two layers of
anti-fouling between the tunnel and the props.
• With the boat on land, run the thruster for a fraction of a second, as
without resistance it will accelerate very fast to a damaging rpm.
• While the thruster is in the air, ensure that the propellers have come to a
complete stop before performing a directional change of the thruster, as
it might cause damage to the thruster.
• Don’t install the electromotor at close range to easily fl ammable objects
as it will reach over 100°C before the temperature switch is activated.
• Do not store items close to the thruster motor as it can reach 100°C.
Any loose items near the thruster motor can cause problems with
electrical wiring coming loose and short-circuiting.
• Ensure that the external stern thruster assembly does not disturb the
water fl ow under the hull. At higher speeds, if the thruster is installed to
low can cause damage to the thruster, additional drag and unwanted
water splashing.
• The recommended tunnel depth from the water surface is 140mm
(5,51‘) to the centre of tunnel diameter.
• Ensure that while installing the thruster it does not foul existing
equipment inside the boat like motor bedding etc.
• If able ensure that sterndrives/ trimtabs do not interfere with the
water fl ow from the thruster as this will reduce the thrust eff ectiveness
considerably. We recommend the use of our Side-Power cowls to
enhance the performance and allow installation in shallow draft boats.
Side-Power cowls will also minimise the eff ect if sterndrives/ trimtabs
obstruct the thruster.
• Ensure there is enough space both inside and outside the transom of
the boat and the thruster does not get in confl ict with existing equipment
inside the boat like steerage links etc. (NB: It is possible to mount the
tunnel off set from the boat’s centre line if necessary.)
• If the stern width is too thick to fi t the thruster correctly, the surrounding
material can be removed from the area.
(NB: A naval architect/boat
builder must confi rm this work.)
• Seal all drain holes going into the compartment of the thruster.
• The surrounding compartments and any plates or compartments
above must provide adequate drainage to the bilge area away from the
thrusters installation compartment.
• Side-Power stern thruster kits include a cable, so the electronic control
unit generally placed on the electric motor, can be fi tted away from the
thruster in a higher position ensuring it stays dry at all times.
