Discontinued thruster
Sleipner SRLP170 PRO (discontinued): specs, manual and parts
The Sleipner SRLP170 PRO is a retractable thruster. It drops out of the hull when you use it and folds back up after. Sleipner has discontinued it. Its own product page said so when we read it on 11 October 2026.
This page stays up for the owners still running one. It holds the published figures, the part numbers and the manual. You will not find the unit in the thruster finder, the tool here that matches a unit to your boat, or on the compare page. If you need a new thruster, start with either of those.

What the manual and listings say
A retractable: it swings down out of a housing in the hull when used and folds back up after. It goes in through a large opening below the waterline, a bigger yard job than a tunnel. PRO means proportional: the joystick sets how hard it pushes. Twin propellers in a 250 mm tunnel, for boats of about 49 to 72 ft.
Sleipner rates it 210 kg (463 lb) at 24 V and 170 kg (375 lb) at 21 V. Sleipner's own page names the ERL170 eVision as its replacement.
Replacement and close alternatives
The replacement: Sleipner ERL170 eVision. Sleipner’s own page for this model links it as the replacement.
