Auto Trim Down
When the operator assumes control of the vessel with the joystick and one or more drives is trimmed above the preset
position, a pop‑up notice will appear on the VesselView display. Similarly, if Skyhook is engaged with one or more drives
trimmed above the preset, the pop‑up will appear. This notice will disappear after 10 seconds, but the operator is provided a
full 15 seconds during which to initiate the auto trim down function.
To initiate auto trim down, briefly press the trim all down button on the ERC or trim pad. Any drive trimmed above the preset
position will be automatically trimmed down to the preset position. To halt the auto trim down of a particular drive, push either
trim button (up or down) for that drive. To halt the auto trim down of all drives, push either trim all button.
IMPORTANT: The preset position for auto trim is accurate to ± 3°, meaning that auto trim in either direction can overshoot by
as much as 3°. If one drive is auto trimmed up and the other drive is auto trimmed down, the drives may be trimmed differently
by as much as 6°. This is not a malfunction.
To bring the drives to the same auto trim position:
1. With the engines off, but the key switches on, trim the drives to their full down position. Hold the trim button for an
additional three seconds.
2. Start the engines.
3. Enable auto trim.
4. Engage the joystick or Skyhook. The drives will all auto trim up to the same position.
Premier Features (If Equipped)
VesselView Autopilot Screen
The VesselView autopilot screen displays:
• The angle of the drives when in standby mode
• A digital compass value of the current heading
• Three icons to indicate the currently selected response level
• Engine RPM
a - Heading
b - Steering angle reference
c - Engine RPM
d - Response level
Skyhook Station Keeping
Your vessel is equipped with the Skyhook station keeping feature. This system uses global positioning system (GPS)
technology and an electronic compass to automatically control shifting, throttling, and steering to maintain heading and
approximate position. This feature can be helpful when waiting for space near a fuel dock, waiting for bridges to open, or when
the water is too deep for an anchor.
Skyhook does not maintain an exact fixed position, but rather will hold the vessel in a fixed compass heading within an
approximate area. The size of this area is affected by the accuracy of the global positioning satellite system, the satellite signal
quality, the physical position of the satellites relative to the receiver, solar flares, and the proximity of the receiver on the vessel
to large structures (for example, bridges or buildings) and trees. Under some of these conditions Skyhook may be affected
enough that the system will disengage. The operator must remain at the helm whenever Skyhook is engaged and be vigilant for
changing conditions such as the presence of other vessels or swimmers or the disengagement of Skyhook.
