Performing the Autotune Procedure

Before you can begin this procedure, you must have a large stretch of open water available.

1 Engage the kicker motor in forward gear at moderate speed.

2 Steer the boat by hand and point in a direction with at least 100 to 200 m (100 to 200 yd.) of open water.

3 Select an option:

• If you are performing this procedure as part of the Sea Trial Wizard, select Begin.

• If you are performing this procedure outside of the Sea Trial Wizard, on a helm control or the autopilot

screen on a chartplotter, select

Autotune > Begin.

The boat performs various zigzag motions while the Autotune is in progress.

4 After the procedure is finished, follow the on-screen instructions.

5 If the Autotune procedure is not successful, select an option:

• If the Autotune procedure is not successful and you have not reached maximum cruising speed, increase

the speed, select Run Standard Autotune and repeat steps 1 through 3 until the Autotune procedure

completes successfully.

• If the Autotune procedure is not successful and you have reached maximum cruising speed, reduce your

speed to the initial Autotune speed, and select Run Alternate Autotune to begin an alternate procedure.

• If the Autotune fails immediately and you are traveling in a circle instead of performing zigzag motions,

select Switch Direction > Run Standard Autotune and repeat steps 1 through 3 until the Autotune

procedure completes successfully.

When the Autotune procedure is complete, gain values are displayed. You can use these values to determine the

quality of the Autotune procedure.

Autotune Gain Values

After the Autotune procedure is complete, you can review the gain values provided on the helm control. You can

record these numbers for reference if you want to run the autotune procedure at a later time or if you want to

manually adjust the gain settings (not recommended)

Gain: Sets how tightly the autopilot holds the heading and how aggressively it makes turns.

Counter Gain: Sets how aggressively the autopilot adjusts any over-steering after making a turn.

Setting North

This procedure appears if the autopilot is connected to an optional GPS device, and the device has acquired
