Your Volvo Penta propulsion system is equipped with a Power Trim hydraulic trim system which makes it possi-
ble to adjust the angle of the drive in relation to the stern of the boat. This adjusts the boat’s trim to obtain maxi-
mum comfort and fuel economy in different operating conditions.
Power Trim settings and adjustment are controlled from the helm position using the controls and instruments de-
scribed in this chapter. The section on Operation provides more information on use of the Power Trim system
when operating the boat.
WARNING! Avoid over-trimming the drive system as this can adversely effect the steering of the boat se-
verely.
Trim controls
The drive is trimmed using the separate control panel or the button
on the control lever (option). The current trim position of the drive is
shown on the separate trim instrument.
Trimming the drive away from the stern of the boat raises the bow in
relation to the horizontal, while moving it towards the stern will lower
the bows.
Button 1: Press button to lower the bow of the boat (drive is
trimmed inward).
Button 2: Press button to raise the bow of the boat (drive is
trimmed out).
Button 3: Press the button* while simultaneously pressing button
(2) or (4) is pressed up to raise or trim the drive out to
Beach range.
Button 4: Press button up to raise bows. Press button down to
lower bows.
* Applies only to DP. This button has no function on the DPX drive.
Trim instrument. General
To be able to make use of the information provided by the trim in-
strument it important to know about the significance of the trim
ranges and their application. There are three ranges:
Trim range
The trim range is used to achieve maximum comfort under normal
operation at all speeds from start to maximum speed.
Beach range
The beach range is used for operation at reduced speed in shallow
water or where water depth is uncertain.
WARNING! The maximum permitted engine speed in the
Beach range is 1,000 rpm. Always check that the cooling
water intake is below the surface of the water.
