Lewmar bow thrusters give you sideways control for tight docking and crosswinds. Find 12-volt tunnel thruster kits along with control cables, fuses and tunnel kits to complete the install.
Choosing a Lewmar Bow Thruster
Start with thrust rating and boat size. Lewmar sizes its tunnel thrusters by thrust and power, such as the 110TT and 140TT kits, and a thruster must be matched to your boat length and windage to push the bow effectively. Underpowering a heavy boat leaves you short in a strong crosswind.
Plan the full system. A tunnel thruster needs a tunnel kit molded into the hull, plus a control cable run to the helm and a correctly rated fuse to protect the motor. Lewmar offers control cables in several lengths, so measure the run from the thruster to the joystick. Most kits are 12-volt, so confirm your house voltage. A stern thruster adds matching control at the back of the boat. Confirm thrust, voltage and cable length before ordering.
Frequently Asked Questions
How do I size a bow thruster?
Match the thrust rating to your boat length and windage. A heavier boat or one with high windage needs more thrust to move the bow in a crosswind.
What else do I need besides the thruster?
Plan for a tunnel kit in the hull, a control cable run to the helm and a correctly rated fuse to protect the motor.
Are Lewmar thrusters 12 volt?
Most tunnel thruster kits run on 12 volts. Confirm your house battery voltage matches the kit before ordering.
