SeaStar Power Assist Pro System

The ultimate in steering comfort

The SeaStar Power Assist Pro System can be
installed on new SeaStar steering installations or as an easy
retro-fit to existing systems. Suitable for most boat types, the
Power Assist uses an electronically controlled hydraulic pump to
provide on-demand power steering.

The system is designed to be easily installed into the hydraulic
steering circuit between the helm and steering cylinder. An
additional feature allows the Power Assist Pro to adjust
automatically to the input voltage from the boats batteries to
either 12V or 24V. The SeaStar Power Assist can be used on boats
with multiple engines and rudders, multiple steering stations and
autopilots.

As a built in safety feature the steering system will automatically
return to manual operation without any change to the number of
lock-to-lock turns if power to the unit is interrupted for any
reason. The SeaStar Power Assist helps eliminate steering loads and
provides high levels of comfort and control making boating more
pleasurable. The SeaStar Power Assist allows the boat to be driven
safely and easily even in the most extreme conditions.

How it works
SeaStar Power Assist steering uses an electronically controlled
hydraulic pump to provide “Power” for your SeaStar Hydraulic
Steering system. The system is comprised of two circuits: a hand
operated manual system, which is the control element, and a
hydraulic power pump, which is the working element.

The manual system consists of a helm pump with internal relief and
check valves, as well as a built in reservoir. Two steering lines
and a compensating line which provide a routing for fluid to
transmit through the system, and a steering cylinder which moves
the steering device on the boat from side to side.

The power system, is an electronically controlled hydraulic pump
that boosts the fluid being sent from the helm pump to the steering
cylinder (this will result in much easier effort at the wheel—even
when under heavy loads). A compensating line connects the P/A unit
to the helm pump, allowing the P/A unit to share fluid with the
helm reservoir.

The SeaStar Power Assist is compatible with multiple steering
stations, and with the use of an autopilot. In the event of a P/A
power loss or failure the hydraulic system will automatically
revert to a manual hydraulic system.
