Lewmar 110TT Tunnel Thruster Kit
#5 in Under 45 kgfFull review
A kit for a small boat up to about 28 ft that wants everything in one box. Sleipner SE30 gives more thrust for about the same money.

2.8/5
A small Italian thruster for a boat of about 7 to 9 m. At the only Amazon price found it is poor value next to a Sleipner SE30.

The 140TT 2.0 kW sold as a kit. Compare it against buying a Gen 2 unit and a panel separately.

Only worth it when a tunnel can not be cut, such as a shallow or cored hull. For every other boat a tunnel thruster is far cheaper per kgf.
