Discontinued thruster
Sleipner SEP130/250T-IP (discontinued): specs, manual and parts
The Sleipner SEP130/250T-IP is a tunnel thruster. The motor sits inside the boat and turns a propeller in a tube through the hull. Sleipner has discontinued it. Its own product page said so when we read it on 1 October 2026.
This page stays up for the owners still running one. It holds the published figures, the part numbers, the manual and the last price we read. 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
The ignition-protected build, for a boat with gasoline engines or tanks in the same space. PRO means proportional: the joystick sets how hard it pushes. The 2026 catalog says to expect close to continuous run time at half power or less. Twin props in a 250 mm tunnel for boats of 43 to 62 ft, at 12 V, rated 160 kg.
The page rates the brushed motor for two to three minutes' running at 20 C. The control panel switches itself off after about six minutes unused. Sleipner's FAQ wants the tunnel at least three quarters of its diameter below the surface, never less than half.
Replacement and close alternatives
The replacement: Sleipner E130 eVision. Sleipner’s own page for this model links it as the replacement.
