Throttle Only Operation
NOTE: When operating in throttle only (neutral) mode, the DTS Control System will not allow the engine speed to increase above
3500 RPM.
Console mount remote controls are equipped with a throttle‑only button. To activate throttle only mode:
1. Refer to the
Remote Controls
section for remote control features.
2. Move the control lever to the idle/neutral position.
3. Depress the throttle‑only button, and move the control lever to the idle/forward or idle/reverse position. The DTS control system
will sound two beeps on the audio warning horn to indicate throttle only mode is active. On console mount remote controls,
the neutral light will begin to blink.
4. Advancing the control lever beyond the idle/forward or idle/reverse position will cause engine speed to increase.
IMPORTANT: Moving the control lever back to the idle/neutral position will not deactivate the throttle only mode or allow the
engine to shift into gear.
5. Throttle only mode is deactivated by moving the control lever to the idle/neutral position and pressing the throttle only button.
Moving the control lever from the idle/neutral position to the idle/forward or idle/reverse position without pressing the
throttle‑only button will just increase the engine speed. Be sure to take both engines out of throttle only before use.
Traditional Maneuvering with Steering and Thrust
You can maneuver your Axius‑equipped vessel much like a traditional sterndrive boat. However, the Axius drive system expands
the maneuvering capability of your vessel at both slow and planing speeds. At slow speeds, the drive system is capable of directing
the thrust to produce more responsive turning of the vessel. The Axius drive system features counter‑rotating propellers that do
not produce any sideways motion when accelerating or slowing down.
NOTE: During slow‑speed turning with the wheel, the drive on the inside turns as much as 42° to create very tight turns. Unlike
traditional boats, you can increase power to the inside drive to tighten the turn.
To Maneuver the Boat in Forward
Place one or both engines in forward gear and steer with the steering wheel as you would any comparable boat.
To Steer the Boat in Tight Turns at Low Speeds
•
To turn the boat in tight turns at low speeds, turn the wheel in the direction of the turn.
•
To increase the turn rate of the boat after the wheel is completely turned, you may increase the power to the inside drive.
To Spin the Boat at Low Speeds
•
To spin to the right, place the starboard engine in reverse and the port engine in forward.
•
To spin to the left, place the port engine in reverse and the starboard engine in forward.
•
To increase the rate of turn, simultaneously adjust each ERC lever for more throttle.
Maneuvering with the Joystick
!
WARNING
A spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers.
Stop the engine immediately whenever anyone in the water is near your boat.
The joystick provides an intuitive driver interface to maneuver the vessel. Operating the vessel with the joystick is well suited for
close quarter operations and when docking. The computer control system automatically calculates the steering angle of each
drive, the throttle level, and the proper gear to push or rotate the boat in a direction corresponding to a joystick movement or twist.
For example, if you move the joystick sideways, the computer control system applies a thrust to the boat in the sideways direction.
Rotating the joystick prompts the computer to create forces that rotate the boat around its center. You can move and rotate the
joystick at the same time, allowing intricate movements in tight quarters.
The joystick is proportional, which means that the greater distance from the center that the joystick is moved, the more thrust that
is applied to the boat in that direction, to move the boat.
The computer control system automatically attempts to dampen bow swinging during joystick operation. If the joystick is not twisted,
the computer measures the yaw rate of the boat and actively counteracts the yaw motion of the boat.
For joystick movement of the boat:
1. Both engines must be running for the Joystick to operate.
2. For best control, trim both drives to the full down position.
3. Move both electronic remote control (ERC) levers to the neutral position.
