The Kobelt 7166 electric helm is used as an input to Full Follow Up (FFU) electronic steering
systems. The operator can maneuver the vessel by moving the helm wheel port or starboard
to operate its internal potentiometer. The helm allows 2-2/3 turns from hard-over to hard-
over and is equipped with a single potentiometer. The shaft is machined with a standard ¾”
taper.

4INSTALLATION
4.1 MECHANICAL
The electric helm must be mounted on a flat surface and stiff enough to withstand the
operating forces imposed during normal use without excessive flexing. Use the template at
the back of this manual to make the correct cut-out on the mounting surface.
The control head is equipped with (3) three 1/4UNC tapped holes for direct mounting to the
dash. Ensure the unit is securely fastened, preferable with an anaerobic thread locker such as
Loctite 243.
4.2 ELECTRICAL
The 7166 electric helm potentiometer has solder terminals. Use 18 AWG wire for external
connections to an electrical junction box. The potentiometer is accessible by removing two
screws on the rear cover with a Phillip’s head screwdriver. The product’s terminals contain
the following connections and related functions:

4.3 COMMISSIONING
Ensure that the rear cover is installed and secured before powering
on the 7166.
•Confirm that the electrical connections to the 7166 have been made.
The Functional Test should be carried out while the vessel is still at
dock and before it is taken out to sea after installation has been
completed.
A complete functional test should be performed on the system that the helm has been
installed within before entering operational use.
