Lewmar Thruster Features

Great care and attention to detail goes into the design and manufacture of every Lewmar thruster. High performance, ease-of-use and reliability are our priorities. In order to achieve that, every thruster we make includes the features below. If you choose a Lewmar thruster, one thing is certain; you need never worry about a tricky docking manoeuvre again.


  • Custom-made to Lewmar specifications, the motors are highly reliable and high performance. Replacement brushes are available.
  • Easy plug-together switch connections
  • "Black Box" provides protection for the motor from overheats and incorporates a direction change delay to prevent damage to the motor internals
  • The Lewmar TT anode has a specially designed stainless steel sheath for optimal retention. Secured with a large nut, it is simple to replace.


5-blade propeller produces equal thrust out of the tunnel across the full 110-185 range from a single propeller. The 250 & 300 utilise twin counter rotating props to get the best performance from larger tunnels and higher power outputs.


Lewmar cassette seal gives excellent protection and better sealing than standard lip seal. This enables Lewmar TT thrusters to be installed without the need for a top-up reservoir and its associated maintenance.
