Shadow Drive™ Mounting Considerations
• The Shadow Drive must be mounted horizontally and as
level as possible, with cable ties firmly securing it in place.
• The Shadow Drive must be mounted at least 12 in. (305 mm)
away from magnetic material, such as speakers and electric
motors.
• The Shadow Drive should be mounted closer to the helm
than to the pump.
• The Shadow Drive should be mounted lower than the helm,
but higher than the pump.
• The Shadow Drive must not be connected directly to the
fitting at the back of the helm. There must be a length of
hose between the fitting at the helm and the Shadow Drive.

Power and Data Layout

When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage
caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. In addition,
connecting the power cable without the appropriate fuse in place will void the product warranty.
.
• The Shadow Drive must not be connected directly to a
hydraulic T-connector in the hydraulic line. There must be a
length of hose between a T-connector and the Shadow
Drive.
• In a single-helm installation, there must not be a T-connector
between the helm and the Shadow Drive.
• In a dual-helm installation, the Shadow Drive should be
installed between the pump and the lower helm, closer to the
helm than to the pump.
• The Shadow Drive can be installed in either the starboard
steering line or the port steering line.
The Shadow Drive must not be installed in the return line.
