How it Works
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 and 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.

SeaStar! Simply the best!
SeaStar hydraulic steering systems are simple and efficient. The basic system consists of three main components:
1. the helm pump.
2. the cylinder.
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.
Pro Hydraulic Cylinder:
Kits now include the Seastar Pro front mount (bullhorn) hydraulic Cylinders and has been specifically designed and manufactured to increase feel and control of high performance outboard powered vessels that have a high level of wear and tear and are used frequently.
Key features of the Pro Cylinder include, heavier duty pivot plate bushes that reduce wear in harsh conditions and longer cylinder rod bushes which create a better seal on the end gland. The cylinder is more rigid due to the addition of the key ways on the support rod and support brackets. The patented ‘pivot’ mount design, utilised on the Pro Cylinder, guarantees continuous smooth, comfortable steering, and maximum effi
