SeaStar HK7500A-3 PRO Hydraulic Steering System Kit Without Hoses

SeaStar HK7500A-3 PRO Hydraulic Steering System Kit Without Hoses

The SeaStar PRO (HK7500A3) is designed for high torque SINGLE non-power-assisted up to 350HP outboard applications such as high performance bass boats. 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.

Important: SeaStar Helm Update to -4

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

• You can find the updated HK7500-4 KIT HERE
• 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, we provide the hose and option to upgrade the hose fittings ON US!
• HK7500-4 replaces the HK7500A-3, HK7500 and is the direct replacement

Applications:
