Is the stern thruster available in 12V?
No, it is not. However, 12V batteries can be connected in series to power 24V stern thrusters.
Can the motor fit into the existing tunnel?
Yes it can. On request it is compatible with all standard tunnel sizes.
Does the stern thruster have an on/off switch?
No, the control is proportional. This means that if you only need a small amount of thrust, you can apply just a little power.
Can the motor be used for an extended period?
Yes, the motors are capable of running continuously based on the conditions written down in the manual.
