The Dometic SeaStar HH-6145-4 Sport Tilt 2.0 Hydraulic Steering Helm Pump is the perfect helm pump for many applications and boat types. SeaStar Hydraulic Marine Steering is the smoothest and most efficient steering system available. It's designed for normal pleasure and commercial use where standard rigging arrangements are used. This latest series of SeaStar helms 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 over running steering loads. More durable check valves make the entire steering system more resilient to the rigors of trailering. The revamped design enhances their aesthetics and has introduced a new fill port plug design for easier maintenance. The HH6145-4 model is a direct replacement for the HH6145-3 and HH6145.• Greatly reduced chatter noise that's typically generated by over running steering loads• Improved check valve durability with a more robust design• Better trailering performance as well as longer service life• Eliminated flow noise when coming off hard-over position• Decreased clicking sound of the lock valve spool during steering reversal• Tighter, more responsive steering resulting in better "regrip" performance• Full compatibility with existing SeaStar hydraulic steering systems• Newly designed tilt mechanism• Smooth operation and feel• 48° of tilt articulation• 5 wheel positions for adjusting to most comfortable steering position• Standard 3/4" tapered steering shaft• Accepts wheels up to 20"• Remote fill pointSpecsModel: HH6145-4Displacement: 2.0 cu. in.
