Sleipner SE30 Single Prop Thruster - 12V, 2HP, 66 lb Thrust, 4.9"/125mm Tunnel

Thrusters make for safe and easy maneuvering in close quarters. They provide extra confidence when approaching and leaving the dock – especially in windy or tricky current 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.
Sleipner thrusters are known for outstanding performance and reliability, ease of installation, unrivalled electronic safety features, and their new proprietary high performance 5-blade curved edge Q-props.
They rate their thrusters very conservatively – based on real life measurements with nearly dead batteries (10.5V or 21.0V). All Sleipner performance specs are based on actual propeller thrust in actual installations, rather than theoretical motor specs like horsepower or kilowatts.

The ultra-compact SE30 thruster delivers 30 kg/66 - 85 lb of thrust (depending on battery charge level) in a package small enough to fit in boats as small as 20 ft. Typically these would be boats with high windage designs.
A sealed gear leg, high-performance prop and easy-access anodes make it a powerful and easy-to-maintain addition to any smaller boat.

Thruster features -
• Suitable for boats from 20 to 28 ft in length*
• Extra quiet, high thrust 5-blade curved edge propellers
• Purpose-built, high copper content, electric motors designed for maximum performance at real-life voltages provide exceptionally long run times
• Use of Sleipner's SM10112N or SM15112N Voltage Conversion Boxes allows the use of 24 volt thrusters on 12 volt boats (additional 12V battery is required)
• Gear housing maintains positive oil pressure to prevent water infiltration
• "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
• 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
• All models can be installed as stern thrusters
• World-wide dealer support
• 2-year limited warranty
• A complete installation includes the thruster, a tunnel, choice of control panel, wire harness, and power switch and fuse; all purchased separately

*Note that our vessel length recommendations are only guidelines. Every vessel has different characteristics affecting the functioning of a bow thruster, and 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.
This 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 that 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.
