Tools Needed
• Safety glasses
• Drill and drill bits
• Wrenches
• Torque wrench (if configuring the pump for an unbalanced steering cylinder)
• Wire cutter/stripper
• Screwdrivers: Phillips and flat
• Cable ties
• Marine corrosion inhibitor spray
• Mounting screws: the pump kit includes mounting screws, but if the included screws are not appropriate for
the mounting surface, you must provide the correct types of screws
• Hydraulic system hardware (
Hydraulic Considerations, page 3
):
◦
Hydraulic hose, -4 [6 mm (
1
/
4
in.) ID] or larger, with machine-crimped or field-replaceable fittings that have
a minimum rating of 1000 psi
◦
Hydraulic T-connectors
◦
Hydraulic shut-off valves
◦
Thread sealant, such as Loctite
®
567
◦
Hydraulic bleeding equipment
◦
Hydraulic fluid
Mounting Considerations
NOTICE
The pump must be installed in a dry location, protected from water and the weather.
• Before you start the pump installation, you must identify the type of hydraulic steering system in your boat
and consult the hydraulic diagrams. Each boat is different, and you must consider the existing hydraulic
layout before deciding where to mount the pump (
Hydraulic Considerations, page 3
).
• Before you start the pump installation, you should verify that you have selected the appropriate pump for the
needs of your vessel. You can reference the autopilot compatibility guide on
• For installations with larger steering cylinders or those requiring higher fluid pressure, you should install the
pump as close to the cylinder as possible, so that preferably no more than 3 m (10 ft.) of hydraulic hose
connects the pump to the cylinder.
• You should mount the pump horizontally, if possible.
• If you cannot mount the pump horizontally, you must mount it vertically with the pump head connectors
facing up.
• You must mount the pump in a location to which you can extend the hydraulic steering lines of the boat.
• The pump has five hydraulic-connector fittings, although only three are used when installing the pump as
recommended. The pump-valve illustration provided in these instructions may be helpful when determining
the fitting layout that is best for your installation location (
).
Mounting the Pump
Before you can mount the pump, you must select a location (
Mounting Considerations, page 2
) and determine
the correct mounting hardware (
).
1 Hold the pump in the intended mounting location and mark the locations of the mounting holes on the
mounting surface, using the pump as a template.
2 Using a drill bit appropriate for the mounting surface and selected mounting hardware, drill the four holes
through the mounting surface.
3 Secure the pump to the mounting surface using the selected mounting hardware.
