H Move both Control Head levers side by side to 100% of the Throttle range.
I Check the engine tachometers to see if they are within 1% of one another.
While synchronized, if the tachometers have a greater than 1% percent difference at any engine RPM,
or if they appear to be continually “hunting” for the correct RPM, refer to section Troubleshooting.
Trolling Valve Adjustments
7.4.3 Integrated Servo Trolling
7.4.3.1 Enabling Troll
Press and hold the Transfer Button for two seconds with the Control Head lever in the Neutral detent.
• The Control Head’s red LED should begin blinking rapidly, indicating that Troll is enabled.
• If not, refer to Section Section 5.7.2.1.1: Function Code L0 – Troll Enable and Control Head
Lever Troll Range.
7.4.3.2 Troll Minimum Pressure Adjustments (Function Code L2)
A The red LED should still be blinking rapidly. If not, enable troll.
B If connected, disconnect the Troll push-pull cable from the Troll selector lever.
C Move the Control Head lever to the Ahead detent.
D Using a Shaft Tach, measure the RPM of the Shaft and record on Table 7-1: Shaft RPM at
Idle.
E Manually move the Troll selector lever while periodically measuring the Shaft RPM. The
typical Trolling Valve can be adjusted so that the Shaft is rotating a 30 to 50 percent of the
RPM’s measured and recorded on Table 7-1: Shaft RPM at Idle
F Once the desired RPM has been reached, scroll to Function Code L2. Adjust the Value as
described in Section Section 5.7.2.1.5: Function Code L2 – Servo Troll Minimum Pressure
until the Troll push-pull cable aligns with the Troll selector lever.
G Enter the Value into memory.
H Leave the push-pull cable disconnected.
7.4.3.3 Troll Maximum Pressure Adjustments (Function Code L3)
A Leave the Control Head lever in the Ahead detent with Troll enabled.
B Manually position the Troll selector lever while monitoring the Shaft RPM. The typical trolling
valve can be adjusted to 70 to 80 percent of the RPM’s measured and recorded on Table 7-
1: Shaft RPM at Idle.
C Once the desired RPM has been reached, scroll to Function Code L3. Adjust the Value as
described in Section Section 5.7.2.1.7: Function Code L3 – Servo Troll Maximum Pressure
until the Troll push-pull cable aligns with the Troll selector lever.
D Enter the Value into memory.
E Connect the push-pull cable.
NOTE: Do not attempt the following adjustments until the Gear Oil temperature has reached a minimum of 140
degrees F (60 degrees C).

Port Starboard
NOTE: On Twin Screw applications, the Troll Minimum and Maximum Pressure adjustments must be done one
side at a time initially. Once each Trolling Valve has been adjusted individually, they must be operated as a pair
and adjusted further, as necessary.
