2PRODUCT DESCRIPTION
The Kobelt 7171 Full Follow Up (FFU) Control Lever is used as an input to FFU electronic
steering systems. The operator can maneuver the vessel by moving the lever port or
starboard to adjust its internal potentiometer. The FFU Control Lever can be used for steering
applications, other marine applications, or industrial installations.
The 7171 can be purchased with electrical switches at the far port and starboard extremes to
handle Non-Follow Up (NFU) mode command signals to the on-board control system.
The 7171 is designed for indoor and outdoor installation with a robust die cast bronze and
stainless steel construction to provide a long service life in a harsh marine environment. The
standard configuration contains an elegant polished chrome jog handle and black surface
finish complements vessel control stations. Optionally, the 7171 can be configured to contain
a small wheel in place of the jog handle.
