The SeaStar helm pump is an axial piston pump specifically designed for manual steering. It has a built-in lock valve to prevent the steering load from feeding back to the driver. The lock valve will not allow the rudder or drive unit to move until you move it with the steering wheel. The lock valve section of the helm also includes a relief valve. This relief valve provides over-pressure protection for mechanical components and hydraulic hoses and fittings.

FAQ

Hydraulic Steering Helms

I have an older Traditional Style Tilt helm, I see that this has been replaced?

This is correct. We have recently launched the new “Classic Tilt”, and this helm will replace ALL Traditional Tilt helms. Your hoses and cylinder will work just fine. The new Classic Tilts have a different style (in regards to cosmetics), and also comes with the newly designed Tilt Mechanism (much better than the previous).

What is the replacement part number for the Tilt Mechanism only?

We offer two models, as follows;
* HA6123 for sport tilt helms (soft rubber boot)
* HA6523 for Traditional and Classic Tilt (hard plastic covers).

I have noticed that the SeaStar helm cover looks different than the old helms..?

This is the new cover for the SeaStar helm pump. Only the cover has changed, you will still enjoy the easy, most reliable steering on the market today. YES – it will work with older helms as well.

I see that the BayStar helm that I just purchase is metal and not a composite like my older one…..why did you do that?

When it came time to re-tool for this product, SeaStar Solutions made several updates and improvements to the BayStar helm, one of which was the metal cover. This will work with all older parts on board your boat. NOTE: You will need to drill out 4 mounting holes for the new helm (the older one had 3).

I have an older model pump and want to install a new SeaStar Tilt helm, what adapters will I need?

Unfortunately you cannot retrofit a tilt helm into the old cut out without filling in the hole in your dash and re drilling.

The SeaStar Hydraulic System

High-horsepower/high-speed boating is here and steering systems must perform at maximum capacity. The SeaStar Hydraulic Steering System is designed to provide that extra margin of muscle when needed. The SeaStar system easily handles Outboard, Sterndrive and Inboard engines in boats up to 50 feet.

System selection, installation and service is substantially simplified with just three major components – helm, cylinder and tube or hose. SeaStar has a comprehensive range of available cylinders to handle a variety of Outboard, Sterndrive and Inboard steering applications. These are suitable for both pleasure and commercial applications. Extra steering stations and/or autopilots are easily added.

SeaStar hydraulic steering is a total commitment to quality, performance and simplicity.

SYSTEM COMPONENTS


 

SeaStar manual hydraulic steering systems are simple and efficient. The basic system consists of three main components:

  1. the helm pump,
  2. the cylinder, and
  3. the hose or tubing required to connect the cylinder to the helm pump.

These basic components are necessary in all applications. However as the system variables increase (e.g.: multiple engines, rudders, steering stations and autopilots), additional components may be required.

1. The Helm Unit

The SeaStar helm pump is an axial piston pump specifically designed for manual steering. It has a built-in lock valve to prevent the steering load from feeding back to the driver. The lock valve will not allow the rudder or drive unit to move until you move it with the steering wheel. The lock valve section of the helm also includes a relief valve. This relief valve provides over-pressure protection for mechanical components and hydraulic hoses and fittings.

2. The Cylinder

The most important differences between the variety of SeaStar steering systems available is the cylinder selection. The SeaStar system has a cylinder for most steering applications.

3. Hoses and Tubes

Required to provide a path for the fluid to flow under pressure from the helm pump to the cylinder.

 

HOW IT WORKS


The SeaStar system is a two-line system. This makes operation very simple.

 

  1. The steering wheel, which is attached to the helm pump, is rotated in the desired direction (i.e.: a turn to starboard or clockwise rotation).
  2. Oil is pumped out the corresponding port from the rear of the helm into the starboard line and then into the cylinder.
  3. This causes the cylinder rod, which is attached to the vessels rudder or drive unit, to move (i.e.: rod moves to port) thus causing the vessel to alter course.
  4. Oil displaced from the opposite end (i.e.: the port end) of the cylinder flows (i.e.: into the port line) back to the helm pump.
  5. For steering in the opposite direction, simply turn the helm the other way.
  6. When no course corrections are required, the integral lock valve holds the rudder or drive unit stationary.

 

SELECTING A SYSTEM


The objective is to match the steering system to the requirements of the vessel. This depends on four things:

  1. type of vessel (i.e.: planing or displacement),
  2. type of propulsion system in the vessel (i.e.: Outboard, Sterndrive, Inboard, etc.),
  3. the number of engines or rudders,
  4. the total power of the engines (i.e.: Horsepower).

Next choose a cylinder that best meets these requirements. Once the cylinder has been selected, the size of the helm pump is predetermined. The options left to specify are:

  1. the number of steering stations,
  2. helm configuration (i.e.: standard or tilt helm),
  3. additional features such as autopilots.

Proceed to the appropriate section of the web site for to make your selections.

Notes on Steering Response versus Steering effort

Steering wheel effort is directly proportional to the number of wheel turns lock to lock. The number of wheel turns lock to lock is dependent on three things:

  1. the volume of the cylinder,
  2. the displacement of the helm pump,
  3. the allowable movement of the rudder or drive unit.

Less wheel turns lock to lock results in more steering effort. More wheel turns lock to lock results in less steering effort. However, additional factors that can influence steering effort are:

  1. vessel speed,
  2. rudder size,
  3. unusual propellor selections,
  4. hull type (i.e.: displacement, planing, etc.), and
  5. steering wheel size.

Recommendations made on this web site are guidelines based on average acceptance of steering effort.
