The Jefa direct drive is one of the the strongest compact autopilot drives in the world. It’s much stronger than a human being (the max. output torque of 375 KgM is equivalent to 375 Kg force on the end of a 1 meter steering tiller) and is build for 24 hours per day continuous operation with a total weight of only 19 Kgs. The combination of the specially designed electric motor with the ultra efficient 3 stage planetary gearbox results in an extremely efficient drive unit to keep the battery charging time to the minimum. The drive can be used on boats from 40 to 55 foot equipped with a mechanical steering system that can be back driven.
The direct drive drives the rudder via a draglink and the existing tiller arm or quadrant or via an independent tiller arm.
