Actuator installation

CAUTION!
This actuator is intended to operate in a primarily dry area that may be
wet or occasionally submerged. It is not intended to operate in a
permanently submerged condition.
NOTICE!
Protect the actuator shaft from nicks and scratches during installation.
A damaged shaft cannot be repaired.
3.1
Install the actuator
NOTE
If you are installing a remote manual override refer to the installation
instructions provided with the kit. You may find it easier to install the
override guide before installing the actuator.
Proper actuator mounting and alignment is important for system reliability, symmetric
steering, and for maximizing the output rudder torque throughout the steering range.

defined by an imaginary line drawn through the tiller arm hole at both hard over positions.
WARNING!
Mount actuators using through-bolts and self-locking nuts. Use of lag
screws may result in separation of steering components, leading to loss
of steering control. Loss of steering control may result in a collision and/
or ejection from the boat, leading to property damage, personal injury,
and/or death.
