Use these kits to install a Lewmar Thruster at the stern of your boat.
The T-shaped tunnel directs the thrust from side to side.
Lewmar's high quality filament wound fiberglass bow tunnels come in a variety of cut lengths. Steel tubes are available in some sizes by special order. Fiberglass Stern Kits for mounting on flat powerboat transoms are available for all thruster sizes (thruster not included).
