Seastar HK7500A-4 PRO Hydraulic Steering System Kit

SeaStar HK7500A-4 PRO Hydraulic Steering System Kit Without Hoses

The Dometic SeaStar PRO HK7500A4 Steering Kit is designed for high torque SINGLE non-power-assisted up to 350HP outboard applications such as bass boats, flats, combo race/ski and other high performance oriented boats capable of speeds in excess of 65mph. SeaStar PRO has steered the BASS Masters Classic since 1994 and it's the choice of high performance outboard boat builders. It is suitable for use with high-performance propellers and jack plates. The hose comes standard with brass fittings but you can choose to upgrade to Stainless Steel Fittings, optimal for salt water use. This option is only available with us.

Important Update: Seastar Steering Update to -4

The latest series of kits has been redesigned to provide a better experience for the vessel operator:

• New valve technology ensures tighter, quieter, and more responsive steering, while minimizing the potential for chattering when dealing with overrunning steering loads.
• More durable check valves, making the entire steering system more resilient to the rigors of trailering.
• Revamped Design to enhance their aesthetics, and has introduced a new fill port plug design for easier maintenance.
• Kits with hoses are discontinued, you will purchase the HK7500A-3 kit and hose separately.
• HK7500A-4 replaces the HK7500-3, HK7500 and is a direct replacement.
