Lewmar 140TT 2.0 kW Tunnel Thruster

The older Lewmar 140TT. Buy it only to replace an existing unit; the Gen 2 2.2 kW version gives 5 kgf more for about $225 more.

3.4/5
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.

The current Lewmar for a mid-size boat. Fine if you already have Lewmar controls; otherwise Sleipner is cheaper for the thrust.
