EQUIPMENT AND FEATURES
1-4 53 COUPE
Tilt the steering wheel to a comfortable position by pushing the tilt catch on the
6 o’clock position of the wheel base.
The steering wheel sends a digital signal to the Electronic Vessel Control (EVC)
computer, which sends commands to the IPS drives to rotate accordingly. The
steering wheel will rotate in either direction limitlessly, but a digital stop has been
encoded. No matter how many turns the wheel is given in either direction, the
drives will stop rotating once the digital stop point has been realized. At higher
engine speeds the steering turning degree is more controlled: that is to say,
the angles of turning will be limited at higher engine revolutions (RPMs). At
higher engine speeds a built-in resistance will interface with the wheel, giving
the helmsman the analog feel of force when turning.
The rudder angle indicator on the Multi-Function Displays (MFDs) shows an
approximation of the drive angle.
When the ignitions are turned off, the IPS drive units automatically center.

IPS Joystick Driving
The Volvo ® IPS joystick (
Figure 1-3
) is located on the starboard side of the helm.
All joystick buttons are ON-OFF switches. Press once for ON and a second time
for OFF .
1. The joystick control may be used to steer the boat in place of the steering
wheel, allowing the driver to steer while seated at the helm seat. The joy-
stick also makes docking easier, with intuitive maneuvering that allows the
boat to move sideways or spin on its own axis. When using the joystick to
steer, the throttles still control the engine RPMs. To steer gradually, twist
the joystick in the desired direction. To dodge or turn quickly, push the
joystick to port or starboard and the boat will quickly turn hard. The steer-
ing wheel is in a standby position while joystick driving. To use the steer-
ing wheel, simply turn it and it will become fully available, deactivating the
joystick.
2. The joystick activation button activates and deactivates joystick steering
and engages the autopilot function. The joystick autopilot function is au-
tomatically engaged if the joystick is released, and continues on the last
heading of the joystick. Further joystick driving will adjust the autopilot
heading.
