1 Important Safety
Information
Safe operation of the SeaWays and SeaWays GO integrated autopilot
depends on proper installation and maintenance of the system, as well as
the operator’s safe judgment, boating knowledge, and expertise.
The installer and operator must read and understand the safety requirements
in this section before installing or using the steering system. If you have any
questions about safe installation or operation of this system, contact
Dometic Marine. Please don’t guess.
The symbols below are used throughout this publication to alert you to
potential hazards involved with the operation and installation of this product.
Observe these warnings and notices carefully. The safety alerts alone
cannot eliminate hazards; strict compliance with any special instructions
during installation, operation, and maintenance, along with common sense
operation, are important measures to prevent hazardous situations.
1.1 Explanation of symbols
DANGER!
Safety instruction: Indicates a hazardous situation that, if not avoided,
will result in death or serious injury.
WARNING!
Safety instruction: Indicates a hazardous situation that, if not avoided,
could result in death or serious injury.
CAUTION!
Safety instruction: Indicates a hazardous situation that, if not avoided,
could result in minor or moderate injury.
NOTICE!
Indicates a situation that, if not avoided, can result in property damage.
NOTE
Supplementary information for operating the product.

1-2 EN
General
• Read and understand this manual, the Quick Reference Guide, and any
other documentation provided with your steering system.
• Know and obey all applicable federal, state, and municipal laws and
regulations that govern boating in your area. Dometic recommends all
boat operators take a boating safety course.
• Never operate a boat while under the influence of drugs or alcohol.
Before every use
• Perform the system inspection as described in section 3.1.
• Make sure your Quick Reference Guide and/or this manual is on your
boat. Both contain important safety information that you may need in the
event of a system fault while on the water.
During use
• Wear a Coast Guard-approved personal flotation device (PFD).
• Attach the engine shut-off lanyard to your PFD.
• Do not allow anyone not familiar with the controls (steering, shift/
throttle) to operate the boat.
After use
• Rinse off the steering Actuators/Cylinders thoroughly, using only fresh,
clean water at low pressure. Never use high-pressure water from a hose
nozzle or pressure washer.
• Do not use acetone, or cleaners containing ammonia, acids, or any other
corrosive ingredients, on any Optimus components.
• Some products formulated for cleaning fiberglass hulls are known to
aggressively corrode stainless steel shafts. If using a hull cleaner, avoid
overspray on to the steering Actuators/Cylinders. Rinse off any overspray
immediately with fresh, clean water.
WARNING!
Do not operate the boat if any component is not in proper working order.
It may result in a loss of steering control, which could lead to a collision
and/or ejection from the boat, causing property damage, personal injury,
and/or death.
1.2 Safe operation
WARNING!
The safety information below is intended to inform you of hazards that
may be present when operating a boat equipped with electronic controls.
Read and understand this information.

1-3
EN
Before installation
• Read and understand this manual, and any other manuals supplied with
this system.
• Ensure you have all the required components on hand before you start.
• Do not use a wheel-mounted trim switch with coiled cord. The cord can
wrap around the steering wheel shaft and inhibit steering.
During installation
• Install components as instructed in this manual. Some component parts
and kits may contain additional installation instructions – refer also to
those instructions.
• Do not substitute any component of the system. Dometic parts are
rigorously engineered and tested to ensure system integrity. Substitution
of components may compromise safety, performance,
and reliability.
• If an instruction is unclear, contradictory, or you are otherwise unsure how
to proceed, do not guess. Contact Dometic Marine technical support.
After installation
• Perform the system inspection checks described in section 3.1.
• Correct any interference issues before handing the boat to the owner.
1.3 Safety considerations for installers
WARNING!
The i7X00 System must only be installed by an authorized dealer or
OEM boat builder.
WARNING!
Failure to comply with these instructions may result in a loss of steering
control, which could lead to a collision and/or ejection from the boat,
causing property damage, personal injury, and/or death.

2 Installation
SeaWays and SeaWays GO are integrated autopilot systems. SeaWays
builds off of an Optimus EPS or Optimus 360 system by adding a GPS and
heading sensor. The system uses position and heading data to steer the
vessel automatically.
The SeaWays GPS sensor allows Heading, Track, and Route modes
whereas the SeaWays GO compass allows Heading mode. For more
information on the three modes of operation, please refer to section 3.
Once your Optimus EPS or Optimus 360 system is installed, adding
SeaWays is simple:
1. Install the SeaWays or SeaWays GO sensor
2. Route network cable from sensor to Optimus network backbone
3. Apply Sensor license provided with kit (captured on back cover
of this booklet)
4. SeaWays commissioning
Before installing sensor:
1. Optimus EPS or Optimus 360 must be fully installed and commissioned
2. All software must be up to date – See book 65 for instructions on
updating software
2.1 Overview
2.2 Before you begin

2-2 EN
2.3.1
GPS Reception
When considering where to mount the sensor, consider the following GPS
reception recommendations:
• Ensure there is a clear view of the sky available to the sensor so the GPS
and SBAS satellites are not masked by obstructions that may reduce
system performance.
• Mount the sensor as close to the center of the vessel as possible. This
includes both the fore-aft direction and the port-starboard direction.
• Locate any transmitting antennas away from the sensor by at least several
feet to ensure tracking performance is not compromised, giving you the
best performance possible.
• Make sure there is enough cable length to tie into the Optimus CAN2 or
CAN3 backbone of the vessel.
• Do not locate the antenna where environmental conditions exceed those
specified in the table 2-1 Environmental Conditions below.
Environmental considerations
The sensor is designed to withstand harsh environmental conditions;
however, adhere to the following limits when storing and using the sensor:
VHF interference
VHF interference from devices such as cellular phones and radio
transmitters may interfere with GPS operation. For example, if installing the
sensor near marine radios consider the following:
• VHF radios can interfere with GPS signals.
• Follow VHF radio manufacturers’ recommendations on how to mount
their radios and what devices to keep a safe distance away.
Before installing the sensor use the following diagram to ensure there are
no nearby devices that may cause VHF interference.
2.3 Installing the SeaWays
GPS sensor
Mounting location
This section provides information on determining the best location for
the sensor.
Table 2-1. Environmental Conditions.
Item Specification
Operating Temperature -30°C to +70°C (-22°F to +158°F)
Storage Temperature -40°C to +85°C (-40°F to +185°F)
Humidity 100% non-condensing
NOTICE!
The sensor should be mounted as low as possible while still maintaining
good sky visibility. This will reduce false movement due to the boat
rocking back and forth.
