AUTOPILOTS 55

Know your boat and your steering system

The first step in selecting a Raymarine autopilot from the Raymarine 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 I 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 taking a peek 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 well-skilled and have been

Raymarine trained to evaluate and assist you in selecting the right autopilot for your boat.

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.

TECHTIP

1.1 Hydraulic steering systems

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 corepack.

)

Maximum stall pressure at 12V 50 bar (750 psi) 50 bar (750 psi) 100 bar (1450 psi) 80 bar (1160 psi)

Peak ﬂ ow rate (no load) 1000 cc/min 1000 cc/min 2000 cc/min 2900 cc/min

Corepack used S1 or S1G S2 or S2G S3 or S3G S3 or S3G

• In some systems with dual steering rams in parallel, cylinder capacity is the total of both rams, rams in series only require the one valve.

• Vessels with outboard engines require a rudder reference feedback transducer for optimum performance.

• Hydraulic steering systems with steering rams over 500cc require our larger constant running hydraulic pump used in conjunction with S3 or S3G corepacks - contact Raymarine for details.

• Vessels with 24V DC power must use the S3 or S3G core pack and 24V drive.

• An authorised Raymarine dealer is best suited to installing a hydraulic autopilot system.
