Installation
We recommend that you consult a Raymarine approved dealer who
can specify, install and commission the correct Raymarine system for
your boat. An approved installation also carries our full worldwide 2
year warranty.
Know your boat and your steering system
The first step in selecting a Raymarine autopilot is to choose the proper
autopilot drive unit for your vessel. Raymarine autopilot drive units
are available in an array of sizes and configurations to accommodate
various steering types and vessel displacements.
What type of steering system do you have?
To select an autopilot correctly, you will need to find out what type of
steering system is installed on your vessel. This may involve opening
a few hatches and looking at the gear, or this can be a simple case of
consulting your boat dealer or steering manufacturer.
Raymarine SmartPilot systems accommodate hydraulic, mechanical
and power assisted stern drive systems. If you are not sure how to
determine what type of steering system is installed on your vessel,
please consult an authorised Raymarine dealer. Raymarine dealers
are very knowledgeable with a wealth of experience and have been
Raymarine trained to evaluate your boat and assist you in selecting the
right autopilot.
Drive Unit Selection
Raymarine SmartPilots connect to hydraulic steering systems using
a rugged hydraulic pump matched to the capacity of the hydraulic
steering system. To match a Raymarine SmartPilot hydraulic pump to
your vessel you need to know the size (in cc) of the hydraulic cylinder
ram(s) that is mounted to the rudder on inboard engined boats, or
mounted to the drive unit on outboard engined boats. Your steering
system documentation will have this information. Alternatively, you can
look on the cylinder ram itself for the brand and model number. Once
you know the model number, visit our website (www.raymarine.
com) and access our hydraulic cylinder ram cross-reference guide to
determine which hydraulic autopilot pump is compatible with your
vessel's hydraulic steering system.
Raymarine autopilot hydraulic pumps are available in several sizes to
accommodate the broad range of steering cylinder capacities. The table
below shows the capacity of each Raymarine hydraulic autopilot pump
when used with the corresponding SmartPilot course computers.
Hydraulic Steering Systems
• In some systems with dual steering rams in parallel, cylinder capacity is the total of both rams. Rams in series only require single capacity valve. Hydraulic steering systems with steering rams
over 500cc require our larger constant running hydraulic pump used in conjunction with SPX and SPX-SOL course computers – contact Raymarine for details.
• An authorised Raymarine dealer is best suited to installing a hydraulic autopilot system.
• Type 0.5 suitable for Volvo D4 / D6 Sterndrive applications.
