Thrusters make for safe and easy maneuvering in close quarters. They provide extra confidence when approaching and leaving the dock – especially in tricky current or windy conditions.
While typically mounted in the bow, they can also be mounted in the stern...or both.
Side-Power is now Sleipner – the name of its original parent company.
Available in both 12V and 24V models, the SE100 is an excellent choice for yachts from 35 - 55 ft Where a smaller (7-1/4") tunnel is desired. Depending on battery charge level, the SE100's twin props generate from 220 to 256 lb (100-116kg) of thrust to easily maneuver mid-sized vessels in strong winds and heavy currents.
Sleipner's wide range of control panels and remotes allows you to customize the installation to fit each owner's personal specifications.
If you've arrived on this page already familiar with the advantages Sleipner bow thrusters offer, read on...
Otherwise, this Introduction to Side-Power Thrusters will provide a general overview of their features, propeller configurations, and superior quality.
Thruster features -
• Extra quiet, high thrust 5-blade "skew" propellers
• "Plug and Go" - all electrical components come completely set up - just connect the thruster to the battery
• Sophisticated "Intelligent Power Control" solid state circuitry prevents damage due to overheating or a sudden change in drive direction; "auto-off" feature deactivates control panel after a set period of inactivity
• Child-proof on/off system; no accidental activation
• All models can be installed as stern thrusters
• Purpose-built, high copper content, electric motors designed for maximum performance at real-life voltages provide exceptionally long run times
• Gear housing maintains positive oil pressure to prevent water infiltration
• Lifetime lubricated/ceramic-carbon mechanically sealed drive train, streamlined gear housing, shear-pin (single prop) or flex-coupling (twin prop) drive gear protection, easy access anodes
• World-wide dealer support
• 2-year limited warranty
NOTE — A complete installation includes the thruster, a tunnel, choice of control panel, wire harness, and main on/off power switch and fuse; all purchased separately
The vessel length suggestions we provide are only guidelines. Every vessel has different characteristics affecting the functioning of a bow thruster, additionally, environmental conditions will vary.
Selecting an appropriate thruster for your boat depends more on its exposed surface area (windage) than on its displacement. Windage, in turn, is related to the boat's length and height.
The linked resource article "Thruster Selection Guide" will present you with several bow thruster options for the length of your vessel. You can then make a selection based on your knowledge of your boat's having higher or lower windage than would be typical for a vessel of that length.
After determining the model of thruster that seems best for your needs, please contact our sales department for corroboration or advice at 800-426-6930.
If desired, the installation of Sleipner's SM10112N Voltage Conversion Box allows the use of the 24 volt version of this SE100 thruster on 12 volt boats (additional 12V battery is required; see Accessory Products).

The Side-Power website has helpful system set-up diagrams illustrating how components are selected and used in a variety of possible thruster installations.
When the above link opens, select "Side-Power" for the category, then select a "Type" of your choosing.
"System Diagrams" will present you with a number of basic layouts for various thruster configurations - illustrating the components you need to purchase for a complete system.
These diagrams also indicate where 5-wire cables are needed, and where 4-wire cables are used.
You might also find the "Type" named "Wiring Diagrams" helpful. There is also an excellent "Tunnel Installation Guide" in the list.
Regardless of the thruster system you are considering, and even though it is written for a particular series of thrusters, the link to the "Installation Manual" is an excellent reference. It illustrates many of the general factors and components needing consideration in any thruster installation, including placement of the tunnel, etc.
