The Jefa transmission drive is one of the most compact autopilot drives in the world. It's as strong as a human being (the max. output torque of 150 Nm is equivalent to 30 Kg on the rim of a 1 meter wheel) and is build for 24 hours per day continuous operation with a total weight of only 6 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 30 to 50 foot (or with a rudder torque up to 300 KgM) equipped with a Jefa transmission steering system. Please click on the pictures for a larger view.
