Raymarine Autopilot Systems
Race, Cruise or Fish - Our Autopilot Systems Will Take
Command
The culmination of Raymarines' autopilot expertise, FLIR Systems’ R&D, and
advanced aerospace guidance technology, Evolution Ai™ control algorithms deliver
a new level of accurate autopilot control.
Typical Autopilot systems consist of three main components: a course computer
/ processor, a drive mechanism, and a control head.
Evolution Autopilot
EVOLUTION AI™ – AUTOPILOT INTELLIGENCE
Our Evolution autopilot systems perceive their environment and instantly
calculate and evolve steering commands to maximize performance. The result is
precise and confident course keeping, regardless of vessel speed or sea
conditions - Evolution autopilots steer so accurately they can save fuel and get
you to your destination faster.
Drive Units
The Drive unit is the part that interfaces with your vessel's steering system
to keep you on the right course. Raymarine has a broad range of drive units to
match almost any type of steering system - our Evolution Autopilots accommodate
hydraulic, mechanical and power assisted stern drive systems.
Control Heads
Complete your Evolution autopilot system with an autopilot control head. The
new p70s and p70Rs feature vibrant colour displays and are powered by
Raymarine’s intuitive LightHouse user interface. LightHouse organises all
options into simple menu structures, so with Evolution’s Automagic 3-step setup
process you will be up and running in minutes.

Inboard Autopilots
The Evolution inboard range consists of autopilot packs designed to suit
specific vessel types, steering systems and vessel displacements. Autopilot pack
selection is, therefore, determined by:
- The type of steering system installed on your vessel
- Hydraulic steering systems; the pump has to be matched to the ram (in cc)
- The size and displacement of your vessel - always take the fully laden
displacement of your vessel into account
EV-200
The EV200 system pack controls vessels with any Type 1 drive unit (Hyrdraulic,
Linear, Sail or Power).
EV300-Solenoid
The EV300 system is for use with electric solenoids that control the vessels
hyrdraulic steering system.
EV-400
The EV400 pack controls vessels with any Type 1 to Type 3 mechanical or
hyrdraulic drive units.
EV-2 For Drive-By-Wire Propulsion
EV-2 has been designed for the latest drive-by-wire steering systems and
connects directly to Raymarine’s SeaTalkng bus. EV-2 also has a dedicated CAN
Bus port for direct connection to steer-by-wire steering systems such as ZF Pod
Drives, Yamaha Helm Master, Volvo IPS* and SeaStar Solutions Optimus systems.
This Evolution system pack is designed for
use with the latest drive-by-wire steering systems.

Selection Chart Notes
The recommended Raymarine pump in the table above has been determined by
cylinder displacement alone and should result in a nominal hardover to hardover
time of 10 secs. The formula below can be used to determine the hardover time:
Hardover Time = (Ram Capacity) X 60 (Peak Flow Rate)
Note 1: Where the choice of two or more pumps are indicated the type,
displacement and steering characteristics of the vessel should be considered. By
choosing the larger pump with an increased flow rate a faster hardover time can
be achieved, which on some vessels will result in improved Autopilot helm
response and course keeping.
Note 2: The ram indicated is outside the Raymarine range of pumps.
The information given in this document should be used for guidance only, if
you are in any doubt as to the correct drive unit contact Raymarine's Customer
Support Team for further application advice.
