Mounting the Hydac 2.1 L Pump
Mount the pump horizontally on a solid surface, preferably on the floor. If necessary, you can also mount the pump horizontally on a wall. If
horizontal mounting is not possible, do not install the pump vertically with the pump manifold (containing the hose fittings) pointing down.
Mount the pump within 19 in. (.5 m) of the ECU. Mount the pump as close as possible to the steering cylinder, in a location where you can
extend the hydraulic steering lines of the boat.
To mount the pump:
1. Determine the best location for the pump on your boat, satisfying the hydraulic and wiring considerations.
2. Determine the correct type of screws or bolts for the mounting surface. Mounting screws are included with the pump, but you may need to
provide screws suitable for the mounting surface.
3. Use the mounting template provided on
4. Drill pilot holes at the four mounting locations.
5. Use screws to mount the pump.
6. Use a spray-on corrosion blocker on the pump after it is mounted and all hydraulic and electrical connections are made.
Connecting the Hydac 2.1 L Pump to the Hydraulic Lines
Before disconnecting any hydraulic lines on your boat, consult the manufacturer of your boat or steering system. You must know how
to properly prepare the hoses for removal, and you must know how to properly bleed the hydraulic system of air when you complete the
connections. When adding hydraulic hose to the steering system, only use hose with machine-crimped or field-replaceable fittings that
have a minimum rating of 1000 lb/in

Install the Hydac 2.1 L pump in line with the hydraulic steering lines of the boat. The Hydac 2.1 L pump manifold has five hose-connector
fittings, three to the helm (port, starboard, and return), and two to the cylinder (port and starboard). Do not use Teflon tape on any hydraulic
fitting. Use an appropriate thread sealant such as Loctite Pro Lock Tight multipurpose anaerobic gel, part number 51604, or equivalent, on all
pipe threads in the hydraulic system.
Use the built-in bypass valve on the pump manifold when bleeding the hydraulic lines. See
NotE: Ensure that the built-in bypass valve on the pump manifold is fully closed during normal operation to avoid possible autopilot performance
degradation.
