Mercury MERCRUISER - Engaging (Activating) Skyhook

Section 3 - On the Water
90-899883295 JUNE 2008 Page 59
The capability of most vessels limits the ability of Skyhook to counteract currents of up to
2 knots (2.3 MPH) when the boat is sideways to the current. If you notice your boat drifting
sideways while Skyhook is engaged, move the bow or stern more directly into the current
to help reduce the effects of the current.

WARNING
When the Skyhook is engaged, the boat stays in a preset position; however, Skyhook
can disengage unexpectedly. When Skyhook disengages, the boat does not hold the
preset position and may drift, causing the potential of damage or personal injury. The
helm operator must be able to take control of the boat when using Skyhook.
Skyhook relies on an operational GPS receiver and operational heading sensor.
Occasionally, due to imperfect satellite communications, the GPS signal may be
temporarily unavailable. Skyhook will continue to operate through a GPS signal outage for
up to 10 seconds, but disengages if the GPS signal outage persists. If Skyhook disengages,
you are alerted by the sound of a horn and the indicator light on the Axius Premier touchpad
for the "SKYHOOK" button turns off. In such a circumstance, the boat will drift with the wind
or current because the engines continue to run but the drive units are now in neutral.
Skyhook performance is largely dictated by the performance of the onboard Zeus GPS
system. The Zeus GPS system is accurate within 3 meters (10 feet) when receiving a Wide
Area Augmentation System (WAAS) correction. WAAS is a system of satellites and ground
stations that provide GPS signal corrections. When WAAS is not available, the
performance of the system maintains the boat within 20 meters (60 feet) of the desired
position.
ENGAGING (ACTIVATING) SKYHOOK
IMPORTANT: Activities in the water near the vessel while Skyhook is engaged may result
in injury. The Captain (or operator) and passengers should read and observe the warning
labels on the boat before Skyhook is engaged.
