Highly reliable and high performance
Manoeuvring around the docks can be difficult, but Lewmar’s
185TT Bow Thruster makes it a piece of cake. This thruster
is compact and designed for precise control and optimum performance
in awkward and confined situations. Its unique TT propeller
achieves perfectly even thrust in both directions, providing
maximum control and manoeuvrability. This results in a smooth,
efficient and quiet performance that will have you docking like a
pro in no time.
Casette Seal
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.
5-Blade Propeller
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.
