Emergency manual steering override

NOTICE!
If you manually reposition a steering actuator:
• it must be recalibrated before returning to normal operation .
Recalibration can be done through the CANtrak Maintenance menu,
but it is recommended that the recalibration be performed by an
authorized dealer whenever possible.
• the support bracket clamp bolts must be tightened to the correct
torque before returning the boat to service (see section 5.2.2).
In the event you need to use Limp Home mode, use the following
procedure to manually reposition the affected engine(s):
CAUTION!
Shut off all engines and wear a PFD. This procedure requires you to work
at the transom of the boat, and/or in the splashwell. Please take every
possible safety precaution.
1. Use the emergency override tool included with your documentation
package to loosen the flange bolt that is securing the ground strap to
the starboard side of the actuator (step 1 in figure 4-2). If you do not
have the tool you will need a 3/8" wrench or socket. Loosen it enough
that the ground strap tab will be free to rotate around the bolt when
the shaft turns.
2. Use the same tool to loosen both support bracket clamp bolts a (step 2
in figure 4-2).
3. Turn the shaft using the hex-head feature on the port end of the actuator
shaft to manually steer the engine as required (step 3 in figure 4-2).
Check that the ground strap is not binding or wrapping.
4. Reposition the engine as required, then tighten both support bracket
clamp bolts and the ground strap bolt.
