Parts Desk Insights
Best Use Case: Use this tunnel tube when you’re servicing a Lewmar 140TT installation and need the tunnel section itself (not the full thruster unit).
Common Issues: Before installation, confirm your existing tunnel diameter and cut length match the stated 140mm (5-1/2") x 2'6" (75cm) requirement, and verify you have the correct related seals/gaskets for the thruster-to-tunnel interface shown in the thruster’s service documentation.
