optional trolling Mode
The Trolling mode option allows the boat operator to slow the forward and aft speed of the boat for fishing.
Trolling mode is achieved by the ECU electronically adjusting pressure bypass valves in the gearbox, allowing
the clutches to slip.
When trolling is selected (by pressing the separate trolling switch) and the control lever is moved forward, the
boat will start to move at the slowest speed. The factory default configuration for trolling operation is the Split
Trolling mode. This operation allows the operator to perform from minimum prop RPM (full slip) to maximum
prop RPM (full lock up) and then a throttle ramp up with one lever motion. The defaults are: 60% of the lever
movement from gear-idle to maximum prop RPM, with the remaining 40% lever movement used for throttle
control to a maximum of 40% throttle.
The trolling defaults --
as shown in Appendix C
-- can be set to a variety of operating modes. Contact your
dealer for details, or see technical manual.
How to Enter trolling Mode:
1) Move the Control Head lever(s) to the Neutral position.
2) Start the engine(s) if necessary. The system must see RPM in order to permit trolling mode to be entered.
3) Press the separate trolling switch. This places the system in trolling mode. The trolling light will illuminate
to indicate trolling mode is active.
4) When you move the Control Head lever(s) in either the forward or reverse direction, the engine RPM will
remain steady, but the boat should move in the selected direction.
5) To take the boat out of the trolling mode, return the Control Head lever(s) to the Neutral position and press
the Trolling switch.
