The gearhouse / drive legs of most Side-Power DC Electric
thrusters are now fully galvanically isolated / separated from
the electric motor and motor bracket. This ensures that even
if there is an accidental short circuit or a current leak for other
reasons, the immersed parts are not effected as they could be
with direct electric contact.
To provide reliable and safe thruster installations in more
boats, we offer modified versions of our DC electric thrusters
in watertight housings for use in stern and other locations that
may get wet or be exposed to gasoline fumes. These thrusters
are fully ignition protected (ISO 8846) for use in boats with
gasoline engines. They have a hermetically sealed composite
housing around all electric parts. This provides the ignition
protection as no gasoline fumes can enter and be ignited by
sparks.
The other advantage is that the electric parts that could be
damaged by water are also covered and protected, making
these thrusters the ideal choice for other stern thruster in-
stallations where it is difficult to ensure that the thruster will
always remain dry.
SINGLE PROPELLER:
A properly engineered single propeller system will be the
most energy efficient thruster. Its compact design fits easily
into narrow bows making it the perfect match for our smaller
models. With more than 60.000 single propeller thrusters in
use, the Sidepower single series system has proven its reliability.
TWIN PROPELLERS:
The twin propeller system can give more thrust than a single
propeller system in the same tunnel dia meter. This is our choice
for our mid-range models where high thrust is required in a
small tunnel diameter. Due to the compact design and high
performance, the twin models have become the thrusters of
choice among boat builders around the world.
TWIN COUNTER ROTATING PROPELLERS:
Two counter-rotating propellers can give the most thrust at
a good performance ratio in a minimal tunnel diameter. This
system is used in our larger thrusters for maximum power.
The TC models are the favourite thrusters among leading
boatbuilders for their high-end yachts.
S-LINK:
S-link is a ”CAN” based control system with full intelligent
communication between all units in the system, much like a
computer network.
Main advantages include:
- Round, compact and waterproof plugs with unique
keying and color coding to avoid faulty hookup
- Unlimited number of commands or information
transfer on a single cable
- User feedback at panel
- Intelligent troubleshooting.
The thruster gear leg is filled with oil from a remote reservoir
located above the waterline. This generates overpressure,
making an effective seal against water intrusion in the gear leg.

Sealed gear leg with long-life “mechanical” seal where highly

lifetime lubrication.

DC SPEED CONTROL:
A DC Speed Control system contains three main elements -
proportional control panels, a power control unit and a DC
electric thruster - all tied together with the new S-link control
system. The thrusters used in a speed control system is al-
most identical to the familiar SE range of DC thrusters, the
only difference being the addition of a temperature sensor
and a new electronic control box. All mechanical and main
electric parts are from the well proven thruster range pro-
ducedby Side-Power formany years. All 12 & 24 voltDC
electric thrusters produced by Side-Power can be enabled for
DC Speed Control by authorized Side-Power service person-
nel, even the oldest models.

With the ever growing demand for increased performance, we continue to expand our offering of tunnel diam-
eters to allow customers to choose more powerful thrusters in tunnel sizes that will fit in their boat. The latest ad-
dition is the 215mm tunnel, between the existing ø185mm and ø250mm sizes. This size is very important for boat
sizes around the 50’ / 15m mark, where we have seen that boats have become much more voluminous than before,
requiring larger thrusters to achieve the same maneuverability. We will continue to launch new tunnel diameters where
appropriate to let our customers get the performance they want in their boats.
Facts about tunnel sizes:
•Principallyalargertunneldiameterwillalwaysbemoreenergyefficientthanasmallertunneldiameterforthesamethrust.
The factor is water speed, and this is decided by the amount of water you move through the possible opening which is the
square area of the tunnel less the area blocked by the thrusters gearleg.
