<h3>About Seastar Solutions</h3><p><strong>Seastar Solutions</strong> has been a cornerstone of the recreational marine industry for more than eight decades. <a href="/7554-seastar-solutions-seastar-solutions-hydraulic-steering-200917">Founded in 1943</a> and headquartered in Litchfield, Illinois, the company built its reputation under the Teleflex Marine name before rebranding to Seastar Solutions in February 2013. In 2017, it was acquired by the Dometic Group, further expanding its global reach while preserving the engineering heritage that boaters had come to rely on.</p><h3>A Legacy of Marine Innovation</h3><p>Seastar Solutions' story of innovation begins in 1962, when the company introduced the Big-T cable steering system — a revolutionary design that replaced the traditional rope-and-pulley mechanism with a helical cable, fundamentally changing how small boats are steered. In the decades that followed, the brand continued pushing the boundaries of marine engineering, introducing firsts like tilt steering for recreational boats, CANBUS steer-by-wire technology, and award-winning systems like the Optimus 360 Joystick Control System.</p><p>Today, Seastar Solutions products are sold worldwide under the SeaStar, BayStar, Sierra, Prime Line, and Proheat brands — each recognized for quality, reliability, and technical innovation. Whether you're outfitting a weekend fishing boat or a high-performance offshore vessel, Seastar Solutions offers a system engineered to match your needs.</p><h3>Hydraulic Steering: The Heart of the Lineup</h3><p>At the core of the Seastar Solutions catalog is its industry-leading line of <a href="/7554-seastar-solutions-seastar-solutions-hydraulic-steering-200917">hydraulic steering systems</a>. Covering outboard, inboard, and sterndrive applications, these systems — including the popular SeaStar Pro and BayStar series — are the benchmark for smooth, precise helm control. From hydraulic helm pumps and cylinders to hoses, fittings, and complete kits, Seastar Solutions provides everything needed to build or upgrade a fully capable steering system.</p><p>The brand's hydraulic systems are particularly valued for high-horsepower setups, where mechanical steering can become fatiguing and imprecise. By routing hydraulic fluid through a sealed system, these helms deliver consistent feedback and effortless control regardless of engine load — a key safety and comfort advantage for serious mariners.</p><h3>OEM Quality for Aftermarket Needs</h3><p>One of the most trusted aspects of the Seastar Solutions brand is its compatibility across generations of boats. Because the company carries forward the engineering legacy of Teleflex Marine, most legacy steering components integrate seamlessly with current Seastar parts. This makes Seastar Solutions a reliable choice not only for new builds but also for long-overdue upgrades or routine maintenance on existing vessels.</p><p>From control and throttle cables to installation hardware, cylinders, helms, and fluid maintenance kits, Seastar Solutions covers the full spectrum of marine steering and control needs — making it the go-to source for boaters who demand performance they can count on.</p>

This 2.0 cubic inch displacement helm pump is designed for inboard, sterndrive, and outboard boats up to 50 feet, providing smooth, no-feedback hydraulic steering for single engines up to 350 HP or counter-rotating twin engines up to 700 HP combined.

Key Features:

  • 2.0 cubic inch displacement for responsive steering performance
  • 48° tilt range (12° down, 36° up) with 5 positive lock positions
  • Pre-loaded dual tapered bearings for optimized performance and longevity
  • Shaft seals to prevent water ingress and maintain system integrity
  • Compact footprint fits most marine dashes
  • Compatible with boats traveling up to 60 MPH (for higher speeds, see SeaStar PRO series)
  • Can be used in multiple helm station configurations
  • Maintenance-free design for reliable operation

The HH6543-4 replaces older models HH6543-3 and HH6543, offering improved performance with quieter operation, smoother feel, and quicker reaction time. This helm pump is packaged with repositionable O-ring boss (ORB) hose fittings for secure, leak-free connections. As the world's most popular hydraulic steering system, SeaStar Classic helms provide unmatched comfort and precision control on the water.

Important: Use only SeaStar hydraulic steering fluid or Mil Spec H5606 fluid. Never use brake fluid. The fluid cap must remain in the uppermost position at all times. For helm maintenance, use service seal kit HP6032.
