Livorsi DTS Controls
Three/Four Engine Digital Throttle & Shift Installation
NOTICE
This document is written to aid our dealers, boat builders, and company service
personnel in the proper installation or service of our products. Persons who are not
familiar with these or similar products produced by Livorsi Marine, Inc., and who have
not been trained in the recommended servicing or installation procedures should have
the work performed by an authorized Mercury Marine dealer technician. Improper
installation or servicing of the Mercury Marine or Livorsi Marine product could result in
damage to the product or personal injury to the installer or persons operating the
product.
NOTICE
After completing installation, these instructions should be kept with the product for the
owner’s future use.
Notice to Personnel Installing this Kit
The installation of this product requires an installer who is specifically trained to work
on Mercury Marine’s or Livorsi Marine’s digital throttle and shift (DTS) systems. The
installer must be trained in the proper installation, electronic calibration, and operation
of the DTS system. Failure to correctly install this product may make this product and
/or the DTS system inoperable or unsafe for use.
CAUTION
Avoid possible injury or equipment damage. After installing this control, electronically
calibrate the digital throttle and shift (DTS) system. Do not attempt any calibration
unless you have been specifically trained in Mercury Marine’s DTS systems. Improper
electronic calibration of the DTS system will make this control and/or the DTS system
inoperable or unsafe.
Electrical Requirements
DTS equipped boats require that the electrical systems meet the following guidelines:
Use only marine starting batteries with a 1000 mca /800 cca/ 180 amp hour rating
or higher. Deep cycle batteries do not deliver the power required for the DTS
system.
Secure all battery cables with standard hex nuts, tightened to 13.5 Nm (120 lb. in.)
Do not use wing nuts, as they will not secure the battery cables properly.
Ensure that the battery cable size (cross section) meets the minimum size
requirements for the length of cable used. Refer to the installation manual supplied
with the engine.
Ensure that all power supply connections are clean and tight.

Understand the following criteria when selecting a Livorsi DTS Control location:
Mount the control to provide the boat operator with a comfortable and controlling
position during operation and allow sufficient hand and shift/throttle lever
clearance.
Mount the control to provide enough space for harnesses and wiring beneath the
console panel.
If equipped with a trim switch, locate the switch on the side of the throttle lever
closest to the steering wheel.

Cutting the Control Console Opening
1. Remove the Console Cutout page, located at the end of this document.
Important: Hole patterns between the DTS flat base and DTS contour base
differ.
2. Transfer all drill holes and cut lines to the console in a suitable location. Refer to
Dimensions and Clearances for help determining the installation location.
Important: Ensure that the area below the console is clear of any wiring or items that
may hinder or be damaged by drilling/cutting.

surface.
4. Saw between the drilled holes along the cut lines. Cut perpendicular to the
console surface.
5. Set the control into the opening and check for clearance and fit. Remove the
control from the console.

Neutral Safety Switch
The Livorsi DTS Control does not have a neutral safety switch. The start-in-gear
protection is controlled electronically by the propulsion control module (PCM).
CAUTION
Avoid injury or product damage. Obstructions, such as braces and wiring, may be
unseen when looking at the front of the dashboard. Before drilling or cutting any holes
in the dashboard, check the area behind the dashboard for obstructions. Do not drill or
cut when obstructions are present.
