<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>

Designed for single and dual non-power assisted outboard engines up to 350 HP (700 combined HP for counter-rotating duals) with ABYC standard engine tilt tube, this kit is ideal for cruisers, runabouts, center consoles, and offshore fishing boats.

Enhanced -4 Generation Features:

  • Enhanced valve technology provides quieter, tighter, and more responsive steering, minimizing chatter from overrunning loads
  • Stronger check valves with improved durability and resilience, making the system more resistant to the stresses of trailering
  • Refined aesthetics and design with a sleek new look and redesigned fill port plug for easier maintenance
  • Eliminated flow noise, reducing hydraulic noise when coming off hard-over position for smoother transitions
  • Better trailering performance designed to withstand the rigors of trailering for longer service life

Performance Specifications:

  • 5 turns lock-to-lock with 1.7 cubic inch helm
  • Compact Sport Tilt helm with 48° of tilt and 5 lock positions
  • Standard 3/4" tapered shaft
  • Suitable for speeds up to 60 MPH and dual station use (with purchase of extra helm, hose, and fittings)
  • Allows independent engine tilt in dual engine installations

Kit Includes:

  • HH6191 Sport Tilt Helm 1.7 remote fill
  • HC5345 Seastar Pivot Cylinder
  • 2 quarts (2 liters) of hydraulic steering fluid
  • Fittings, oil, and bleeder kit

Important Notes: Hoses sold separately. Dual engine installations require purchase of a tie bar kit and extra hardware. This kit meets ABYC and NMMA steering standards when installed per manufacturer instructions. The HK6400TS-4 replaces HK6400TS-3 and HK6400TS with significant improvements.
