ZEUS TRIM TABS
PORT

TAB
A
Zeus trim tabs are standard equipment on your yacht.
This system is used to adjust the vessel running angle us-
ing both stern drives. The system may be used in con-
junction with the onboard Lenco Easy Glide system. The
trim tab switch panel is located behind the remote control
box for the operator's convenience. The goal is to achieve
the best running plane for the conditions encountered
along with trying to provide the most economical ride.
Note from the photo above there are individual switches
to manually activate the port and starboard drive trim tab
function. (A) is the port drive control switch and (B) is
the starboard drive control switch.
Also, there is an independent "automatic control" switch
(C)located to the far right. This switch uses an icon to
represent when both drive units are engaged in the auto-
matic mode. To engage the automatic trim simply press
the "automatic" trim tab button. The outdrive trim tabs
will automatically adjust to the speed of your yacht as it is
changed. If you press the automatic switch again, it will
disengage this function.
Note that in the manual mode that particular drive tab
will sustain the position the operator chose until the
key switch is cycled off and on or the "Auto" switch is
pressed in. When accelerating on plane using the manual
mode the individual tabs (A) and (B) will not "trim" until
the switches are pressed.

The Zeus trim tab system can be used to offset various
running conditions by using the stern drive trim tabs in
the manual or automatic mode. Some of these conditions
include:
• Accelerating on to a plane
• Offsetting a rough ride
• Correcting an unbalanced load (list)
• Low speed trim
The information found here is general and limited in de-
tail. Read the Zeus owner's manual for further detailed
information regarding the operation of drive trim tab
system.
