| | | Step 1. Drive Unit Selection 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 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. | | |
| | | |
| | | When selecting an autopilot drive unit for a mechanical steering system, the vessel displacement is the determining factor for selecting the correct drive. When determining your vessel displacement, always add 20% to the dry weight of your vessel to account for the added weight of fuel, gear, provisions and people. Raymarine SmartPilot drive units for mechanical steering systems are available in linear, hydraulic linear and rotary configurations. | | |
| | | 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. | | |
| | | |
| | | Mechanical linear drives Our most commonly used drive types for sailing vessels. Raymarine mechanical linear drives provide powerful thrust, fast hard-over times and quiet operation. Mounted below decks, the linear drive moves the rudder directly by pushing the tiller arm or a rudder quadrant. | | |

| | | 1.1 Hydraulic steering systems | | |
| | | |
| | | |
| | | • Current course computers available until spring 2008 only. Notes: • A linear drive unit connects to the rudder stock via an independent tiller arm. Accessory fittings from your steering system manufacturer may be required. • An authorised Raymarine dealer is best suited for installing a linear drive system. • Must be able to back-drive steering system from the rudder. | | |
| | | 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 marine 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. | | |
| | | |
| | | Mechanical rotary drives The rotary drive is designed for power and sailboat systems that can be driven from the helm position through a chain and sprocket (e.g. cable and rod steering systems). The outstanding design of the Raymarine rotary drive unit provides smooth, powerful autopilot controlled steering with quiet operation. Use the table below to select a rotary drive suitable for your vessel displacement. | | |
