SRL80 retract bow/stern thruster 12V
Sleipner SRL80 flange-mounted retractable bow/stern thruster, 12V DC, 185 mm, 4.4 kW, 80-96 kg thrust; compact bevel-gear design for 33-49 ft motor and sail boats.
Description
The SRL80 retract bow/stern thruster 12V (item code SRL80/185T-12V) is a flange-mounted Sleipner retractable DC thruster delivering 80-96 kg of thrust for boats of 35-48 ft. Retracted into the hull when not in use, it causes no drag, and its compact bevel-gear design suits boats with limited height space.
Key features
- Fitted as bow and/or stern thruster
- Fast deployment and retraction using one fast, powerful actuator (185 mm tunnel models)
- Motor assembly rigidly mounted on the retracting casing: no moving parts during retracting operation
- Reliable retracting mechanism designed to avoid sticking
- Flange mounting: the casing bolts to a base (Sleipner mould-in base or builder's own flange), easing installation in different hull materials
- Twin propellers and Q-PROP™ five-bladed skew propeller for quiet operation (expected 20-40% noise reduction in average installations)
- Intelligent power control: minimal delay between drive directions and automatic stop on solenoid lock-in
- Overheat protection with automatic shut-off
- Sealed drive lubrication with ceramic/carbon mechanical seal; flexible coupling
- Plug & Play S-Link™ or analog control wiring; control panel with status feedback
- Available as PRO™ with variable speed control
