Stern Thruster Tunnel Kit - 250TT

Lewmar 250TT Stern Thruster Tunnel Kit (589510)

A T-shaped filament-wound GRP stern thruster tunnel kit that mounts on a flat powerboat transom — everything needed to install a 250TT thruster at the stern for added lateral control on larger vessels.

Why It's Worth It
A stern thruster paired with a bow thruster gives you true sideways control across the full length of the boat, letting you move parallel to a dock rather than pivoting around one end. At the 250TT size, the stern thruster is handling serious thrust loads — the GRP construction is sized and engineered to Lewmar's specifications for this power level, with 6-point M10 fixing pattern for a secure, high-load installation.

Use
Designed for mounting on flat powerboat transoms. The 250mm tunnel diameter matches the 250TT thruster series exactly — the thruster unit is sold separately and must be ordered alongside this kit. Confirm your transom's thickness and layout against Lewmar's installation requirements before ordering.
