Pump Unit: This pump unit is designed for cylinder or cylinders equilivant to 10 - 25 cubic inches only.

The Pump unit will need to be mounted within at least 20” of the ECU. It will need to be mounted in a horizontal position to a solid surface. Do not lengthen or splice the #5 wire or the orange and black power wires. Do not use this pump with an unbalanced cylinder.

Deckmount: The deckmount should be mounted on the dash near the helm.

Electronic Control Unit (ECU): The ECU will need to be mounted within 20” of the pump unit. Most all components in the system connect to this unit, so considerations will need to be made due to access and cable lengths. (Extension cables are available.) Note: Make note of Serial #’s and record them in the Manual.

Compass Ball: The Compass Ball needs to be located in the forward 1/2 of the boat. Mount it in a location where it will not be disturbed or damaged, and protected against wash down or submergence. Mount the Compass Ball no higher than 10’ above the waterline. The Compass may be extended using extensions available from TR-1. The Compass ball will need to be accessed for the Warning Horn, GPS and Shadow Drive valve connections. When making those connections, use the blue connectors provided in the accessory pack.

Tach Sensor Cables: You will need to splice the end of the tach sensor lead to the tach sensor wire from your motor. You may need to refer to a wiring diagram of your motor. The other wire connects to a clean ground. The other end will plug into the ECU at connection # 2 as per wiring diagram. The tach may be extended using shielded twisted pair wire.

Shadow Drive Hydraulic Valve/Sensor: The Shadow Drive is an electronic bi-directional valve. It will need to be mounted as shown in the system layout and can be extended using 18-22 gauge wire to make the electrical connections. It needs to be mounted closer to the helm than to the pump unit, and will need to be mounted horizontally, and as level as possible. (In a dual station helm, mount closer to and below the lowest helm.) Do not mount the Shadow Drive Valve within 12” of any magnetic interference such as speakers or drive motors. Do Not Install valve directly to the fittings at the back of the helm. Be sure to install a length of hose between the fitting at the helm and the Shadow Drive valve. TR-1 recommends a length of hose between Shadow Drive and any Tee. In a single helm installation, do not place a tee in the line between the helm and Shadow Drive Valve. This is very important for the Shadow Drive feature to work correctly. Air can and will get trapped in the valve during installation and bleeding. It’s very important to get all the air out of the Hydraulic Lines, Helms, Pump, Cylinder (s) and The Shadow Drive valve.

Protection

Locate the Pump Unit, the ECU and the Compass Ball in a place where they will not be submerged or exposed to wash down. Spray the installed components with a protective corrosion prohibitive like Bo-Shield or Corrosion X, etc.

Hydraulic Connections

Before starting the hydraulic installation, please verify the type of hydraulic steering in the boat. If it does not match the hydraulic layouts in this manual, call technical support at 1-866-559-0229for specific installation procedures. Examples of steering systems that may need special instructions: Capilano, Hynautic, Latham.

Do not use Teflon tape on any hydraulic fittings. However, for leak free hydraulic system, we do advise you to use an appropriate thread sealant such as, Loctite “Pro Lock” multipurpose anaerobic gel, part number 51604, or equivalent on all pipe threads.

It is TR-1’s recommendation to only use hose with machine crimped on fittings, or field replaceable fittings that have a minimum of 1,000 PSI rating.
