SEP25 PRO™ tunnel bow thruster 12V

The SEP25 PRO™ tunnel bow thruster 12V (item code SEP25/110S) is a compact Sleipner DC bow thruster with variable speed control, delivering 25–30 kg of thrust in a tunnel of only Ø110 mm. It suits motor boats and sailboats up to approx. 24 ft, depending on weight and windage area, and is available for bow installation only. The thruster can be mounted at any angle on the tunnel, and the motor can be rotated 90° on the motor bracket.

Key features

• PRO™ variable speed control for quieter, more precise manoeuvring; hold function in dual (bow and stern) systems; suited to joystick integration
• Patented intelligent power control (IPC) with solenoid monitoring and automatic stop on solenoid lock-in
• S-Link™ CAN-based control with waterproof, keyed and colour-coded plug-and-play cables
• Q-PROP™ five-bladed skew propeller – up to 75% noise reduction in controlled tests, typically 20–40% in average installations
• Overheat protection with power derating to extend run time
• Galvanic separation of immersed parts
• Sealed, lifetime-lubricated gearleg with ceramic/carbon mechanical seal
• Safe start-up: dual 'on' buttons on the control panel prevent accidental activation
