Quick bow thruster set
The propeller has a power of 3 hp and is suitable for boats 7-10 meters long. The propeller has 5 blades and effectively steers the bow of the boat sideways. The propeller oil does not need to be changed, but it lasts the entire life of the propeller thanks to special seals. The only maintenance required is checking the zinc anode, which is also easy to replace. The propeller is not held in place by a zinc anode, so there is no risk of the propeller falling off, even if the zinc anode is heavily corroded.
The patented coupling between the gearbox and the motor is flexible, which protects the system and extends its service life. This means that uneven loads, for example, do not put as much strain on the motor.
The package includes:
- Bow thruster
- Joystick with 6 meter cable
- Fuse box with fuses
Quick has a long history of manufacturing bow thrusters and is a well-established and functional structure. The company manufactures its own products in its own factories and has full control over the entire development and manufacturing process, which guarantees high quality. Quick is a common choice for many boat builders.
For installation, you will also need power cables and a fiberglass tunnel (Ø140) if the boat does not already have one.

Lewmar bow thruster 2.2kW 12V
The unique 5-blade propeller provides balanced thrust in both directions of the tunnel. All TT series propellers have a keyway mounting. Lewmar’s “cassette” seal is more reliable than conventional seals. This allows installation without an additional oil tank. The TT propeller’s anodes are easy to replace thanks to a large replacement nut. Lewmar’s controls represent a modern design, thus fitting into a wide range of control panels. The round shape allows for quick and easy installation. The TT propellers are equipped with an integrated “black box” to protect against operating errors. Motor thermal protection is standard, giving the user complete reliability during operation.
