Seastar Solutions

<h3>SeaStar Solutions: The Gold Standard in Marine Steering &amp; Control</h3><p><strong>SeaStar Solutions</strong>, formerly known as Teleflex Marine, has spent decades earning its reputation as the foremost authority in marine steering and control systems. Headquartered in Litchfield, Illinois, the brand has built a legacy on precision engineering, durable construction, and products that perform reliably in the demanding saltwater environment boaters face every day.</p><p>From weekend anglers piloting small outboard skiffs to captains navigating large offshore vessels, SeaStar Solutions designs its products for the full spectrum of boating applications. Whether the engine is an outboard, inboard, or sterndrive, SeaStar components are engineered to deliver smooth, immediate response between helm and engine — the kind of confidence-inspiring control that matters most when conditions get challenging.</p><h3>A Legacy of Marine Innovation</h3><p>SeaStar Solutions has pioneered several milestones in recreational boating technology, including the first tilt steering system for recreational boats, CANBUS-based steer-by-wire control, and push/pull control cables that set a new benchmark for reliability. These innovations reflect a company that doesn&apos;t just keep pace with the industry — it drives it forward.</p><p>Today, SeaStar&apos;s product catalog spans hundreds of components, all engineered to work together as an integrated system. Boaters trust SeaStar not just for original installations, but for the long-term support of genuine replacement parts that maintain factory-level performance over the life of the vessel.</p><h3>Core Product Categories</h3><p>SeaStar Solutions&apos; depth is best understood through the essential categories it serves. <a href="/7554-seastar-solutions-steering-parts-accessories-201013">Steering Parts &amp; Accessories</a> represent the heart of the lineup — from helm pumps and cylinders to bearings and mounting hardware, every component is purpose-built for precise, fatigue-free control at the wheel. For boaters maintaining or refreshing an existing system, Replacement Cables are a critical touchpoint: SeaStar&apos;s cables are corrosion-resistant, rated for harsh marine conditions, and available in a wide range of lengths and configurations to fit virtually any application.</p><p>For those seeking the ultimate in smooth, effort-free handling, Hydraulic Steering systems are where SeaStar truly shines. Hydraulic setups eliminate the mechanical feedback and effort associated with cable steering, making them the preferred choice for higher-horsepower engines and larger boats. Rounding out the ecosystem, <a href="/7554-seastar-solutions-control-boxes-parts-200286">Control Boxes &amp; Parts</a> deliver the throttle and shift precision that complements any SeaStar steering setup — built to the same standards of durability and fit that define the brand.</p><h3>Why Boaters Choose SeaStar</h3><p>What distinguishes SeaStar Solutions from generic alternatives is the system-level thinking behind every product. Components are designed to work together, tolerances are tight, and materials are selected specifically to resist corrosion, UV exposure, and the constant vibration of marine use. For anyone who spends real time on the water, a steering system is not a place to compromise — and SeaStar Solutions is the brand that serious boaters turn to when reliability is non-negotiable.</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.
