2 Furlex Electric
Furlex Electric is available as a complete kit for both on-deck and through-deck installation.
The electric system is also available as an upgrade of an existing Furlex by replacing the furling line,
drum and line guard assembly with the Furlex Electric Motor unit and related parts in the Furlex
Electric Retrot pack.
Low power consumption
High eciency throughout the electric power and control system. A “sleep mode” is activated to
save power when not in operation.
Powerful enough, but with precise torque limitation.
The electric motor has a computerised controller that monitors the current draw precisely. As soon
as it reaches a pre-set level it cuts out quickly enough to avoid damage to components. The torque
level is programmed into a memory chip so that each size of Furlex Electric has the correct setting.
Resistant to the marine environment
The gear house is machined from high grade corrosion resistant aluminium and andodized.
All stainless parts in 316 or 316L. The electric motor has its own housing which is completely sealed
and individually pressure tested before delivery.
Two speed operation
A double control button makes it possible to operate the
furler with great precision in the low speed mode.
By pushing both buttons at the same time, high
speed is activated.
Locks in both directions
The worm gear is self-locking (40:1) in both directions,
which means that the sail can be furled from either
the starboard, or the port side of the boat.
Emergency operation
The worm gear has a ½” socket that can be reached
from the starboard side. Seldén’s emergency line
driver is included in the delivery kit.
Compact size -minimised weight and dimensions.
The electric motor is compact, still giving enough power.
This is made possible by raising the voltage up to 42V.
Keeping weight and the dimensions in focus during the
design has resulted in a small unit.

3.2 Installation preparation for Furlex TD Electric (Through deck)
Space requirements
Please check that there is enough space for the installation. The dimensions are given in the
section “2.5 Technical Specification”.
Make sure that there is space for the emergency line driver.
Torque bracket installation
When reefed or under full sail, the furling prole is exposed to a twisting load from the sail.
The forestay attachment of the Furlex TDE is not designed to handle this torque load.
For this reason, the Furlex TDE has a bracket at the rear part of the housing. A torque stay shall
be tted from this bracket to the side of the hull.
Without the torque stay the forestay tting may break, possibly resulting in rig failure.
3.3 Installation of the furling system excluding the electric
motor unit
For complete or retrot installation on Furlex 404 systems, please see:

1.
Check that motor unit ts over hub.
Turn the center shaft (A) by turning the toggle
at the upper end of the swivel so that the ho-
les in the shaft aligns with any of four holes
in the holder (B). Check that the two locking
screws (F) t.
Remove screws and motor unit.
2.
Fit the swivel in the boat without the motor
unit. Fit the clevis pin but not the split pin.
Check the following points:
a) Distance between forestay tting and
