The power steering pumps provide the fluid flow to move the
SmartCylinders. The pumps can be mounted to the floor, a vertical
wall or to the transom. The pumps should be in a dry location and
must be able to connect to the PCM with the three foot harness
supplied with the pump. Do a dry fit, with the leads properly run
through the PCM strain relief plate to verify the harness will reach
before permanently mounting the pumps.
4.3.4 Power Steering Pump
this harness must not be extended.
The power steering pump makes a moderate amount of noise when
operational. Try to select a location that will minimize the noise
in the passenger area.
Typical locations for the power steering pumps and the PCM are behind
the helm area on center console boats or in the rear compartment
of cruisers. Don’t overlook the possibility of mounting these items in
the base of the seating area. The mounting location of these items
will have the most impact on the overall ease of installation and long
term system maintenance so take time deciding on the best location.
For mounting dimensions see Appendix A.
Some considerations:
• It is easier to run small electrical harness than hydraulic hoses
and heavy power wires.
• The operator will need to check the steering fluid level in the power
steering pumps on a regular basis.
• The steering service valves
must
be accessible to the operator in
case of emergency. If you can’t locate the pumps in a way that
makes the valves accessible, use the remote service valve kit,
HA5480, as shown in section 4.3.6.
• Service and maintenance operations will be performed for the life
of the boat. The installation is performed once.

Hose fittings can be relocated to
plugged ports if required. (See
figure 4-9, item 1 and 2.) Torque
hose fittings to 18 ft-lb (24 Nm)
and plugs to 50 in-lb (6 Nm).
You can also install 90° fittings
(Kit # HF6004) for additional hose
routing flexibility.

Due to material variability, fitting
installation torque differs between
the power steering pump and the
steering cylinder. Be sure to use
the correct installation torque to
avoid irreparable damage to the
pump housing or cylinder body
when installing an ORB fitting.
