Side-Power SE50 Tunnel Bow Thruster 12V

The SE50 is an electric on/off tunnel thruster, typically used on boats between 27 and 37 feet. The thruster provides 50-62 kg of thrust and is fitted in a tunnel through the boat's bow. With a sealed gearleg, high-performing Q-propeller, and easy-access anodes, this thruster makes a powerful and easy-to-maintain addition to any boat. 

SE50 is also available in PRO version, IP version, or both. Remote control is a popular accessory. See some of the significant product and safety features below. 

Properties

DC ELECTRICAL CURRENT

Powered by direct current

ANALOG

Sleipner analog signal cables with plug-and-go connectors are color-coded to match the wiring diagrams with high-quality connectors to ensure a correct installation.

OVERHEAT PROTECTION

Detect when internal components become too hot. When an unsafe temperature is detected, the switch automatically shuts off the unit to prevent overheating.

GALVANIC SEPARATION

The gear house and drive legs are 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 affected as they could be with direct electric contact.

• Achieved by composite bushings around the bolts and beneath the washers and a bushing in the motor bracket electrically isolating the drive housing from the motor bracket.
• Available on DC electric models with flexible couplers only, where the flexible coupler provides galvanic separation of the motor and gearleg shaft.

SEALED DRIVE LUBRICATION

Sealed gearleg with long-life 'mechanical' seal where highly polished ceramic and carbon surfaces form the only moving sealing surfaces, ensuring protection against damaging water intrusion into the gear leg. Pre-filled with special gear oil for lifetime lubrication.

• 'Mechanical' seals with surfaces of ceramic and carbon for ultimate security against water intrusion

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 Sidepower's smaller models. With more than 60.000 single propeller thrusters in use, the Sleipner single series system has proven its reliability.

Q-PROP

The new 5 blade special skew propellers are the result of over 2 years of development work and thousands of tests. They have been designed to reduce the noise level, while maintaining the exceptional efficiency of the old 4 blade Sleipner propellers. This goal was achieved, andSidepower even chose to make them a little bit more aggressive on some models, increasing the thrust on some thrusters about 5%. Please see individual information on each new thruster for more details.

• Noise reductions of up to 75% measured in controlled environments
• The expected and tested normal noise reduction in average installations: 20-40%
• Will be delivered on all Sleipner models except models with 300 mm and 385 mm tunnel diameter
• Upgrade kits are available for most SP series thrusters with special adaptors

INTELLIGENT POWER CONTROL

The Sleipner unique thruster controller that intelligently protects the thruster from potential inherent problems in all high current applications as well as user faults. It includes several important safety features imperative in a product with such high power, run by DC electrics, as a thruster.

• Provides delay between drive directions
• Monitors solenoid functions to reduce the chance of solenoid lock-in
• Will stop the thruster in case of a lockedin solenoid, without extra user action and even without controlling a main switch.
