Garmin 190-01166-02 User Manual

When the Dockside and Sea Trial Wizards are complete, test the autopilot to be sure it is configured correctly. Test the autopilot first at 

slow speeds (below planing), and then test the autopilot at planing speeds.

1.  Drive the boat in one direction with the autopilot engaged (heading hold). The boat should not oscillate significantly; however, a 

small amount of oscillation is normal.

2.  Turn the boat in one direction using the autopilot. 

Does the boat turn too aggressively or too sluggishly?
When you release the turn button, the boat should overshoot the turn and quickly correct the heading to the point at which you 

released the button. You will notice that the faster you are going, the greater the boat will overshoot the turn.

3.  If the autopilot is configured properly at slow speeds, repeat these tests at planing speed.

If you feel that the heading hold oscillates significantly or that the autopilot does not quickly correct the heading when turning, make 

slight adjustments to the autopilot gain.
If you feel that the autopilot turns too aggressively or too sluggishly, make slight adjustments to the acceleration limiter.

  notE: When you manually adjust the rudder gain (or counter gain), make small adjustments, and adjust only one value at a time. 

Test the change before entering any further adjustments.

1.  Power the GHP 10 on using the advanced configuration power-on procedure on 

2.  On the GHC 10, select 

 > 

 > 

 > 

 > 

 to access 

the rudder gain adjustments. There are two types of gain settings at both low and high speeds:

Rudder Gain—Adjusts how tightly the rudder holds the heading and makes turns. If you set this value too high, the autopilot 

may be overactive, attempting to constantly adjust the heading at the slightest deviation. An overactive autopilot can cause 

excess wear and tear on the autopilot pump.
Counter Gain—Adjusts how tightly the rudder corrects the turn overshoot. If you set this value too high, the autopilot can 

overshoot the turn again when attempting to counter the original turn.

3.  Adjust the setting that you want to change, and test the adjustment. Repeat steps 2 and 3 until the GHP 10 performance is 

satisfactory.

  notE: When you manually adjust the acceleration limiter, make small adjustments. Test the change before entering any further 

adjustments.

1.  Power on the GHP 10 using the advanced configuration power-on procedure on 

2.  On the GHC 10, select 

 > 

 > 

 > 

 > 

 to 

access the acceleration limiter adjustments.

3.  Adjust the setting and test the adjustment. Repeat steps 2 and 3 until the GHP 10 performance is satisfactory.
