<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>

Product Details

The Seastar Solutions HH5273-4 is a front mount hydraulic helm pump featuring 2.0 cubic inch displacement, designed to deliver smooth, feedback-free steering for modern marine applications. This helm pump is the heart of the hydraulic steering system and represents the latest generation with upgraded ORB (O-Ring Boss) fittings for improved reliability and performance.

Key Features:

  • 2.0 cubic inch (32.7 cm³) fluid displacement for optimal steering response
  • Front mount design with 4-7/16" footprint and 3/4" tapered shaft
  • Upgraded stainless steel ORB (O-Ring Boss) fittings for superior sealing and durability
  • Greatly reduced "chatter" noise from overrunning steering loads
  • Improved check valve design for better trailering performance and longer service life
  • Eliminated flow noise when coming off hard-over position
  • Decreased clicking sound during steering reversal
  • Tighter, more responsive steering with better "regrip" performance (precession)
  • Compatible with steering wheels up to 28" diameter
  • Full compatibility with existing SeaStar hydraulic steering systems

Applications:

  • Single and multi-outboard engines up to 350 HP (700 HP combined for counter-rotating twins)
  • Inboard, sterndrive, and outboard boats up to 50 feet
  • Suitable for speeds up to 60 MPH
  • Ideal for center consoles, cruisers, and high-performance hulls

Replacement Information: The HH5273-4 directly replaces previous models HH5273-3 and HH5273, offering enhanced performance with updated ORB fitting technology. The helm can be mounted with the shaft horizontal, vertical, or at any angle in between for flexible installation options.

Backed by Dometic's reputation for quality and reliability, this helm pump delivers the unmatched comfort and control that SeaStar steering systems have been known for over nearly 60 years in the marine industry.
