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 HH5263-4 is a rear mount hydraulic helm pump with 2.0 cubic inch displacement, designed to deliver smooth, efficient no-feedback steering for marine applications. This helm pump is the heart of hydraulic steering systems for inboard, sterndrive, and outboard boats up to 50 feet in length.

Key Features:

  • 2.0 cubic inch displacement for optimal steering response
  • Rear mount configuration with flexible installation angles
  • Suitable for single outboard engines traveling up to 55 MPH
  • No-feedback steering system for enhanced comfort and control
  • Supports single and multi-outboard engines up to 350 HP (700 HP combined for counter-rotating twins)
  • Packaged with re-positionable O-ring boss (ORB) hose fittings
  • Improved check valve durability and reduced chatter noise
  • Better trailering performance and longer service life
  • Full compatibility with existing SeaStar hydraulic steering systems

The HH5263-4 replaces the HH5263-3 and HH5263 models as the direct replacement. The helm may be mounted with the shaft horizontal, vertical, or any angle in between for maximum installation flexibility. The fluid cap must remain in the uppermost position at all times. Use only SeaStar steering fluid or Mil Spec H5606 fluid—never brake fluid.

This helm pump is part of the world's most popular hydraulic steering system, chosen by OEMs for center consoles, cruisers, and high-performance hulls. It delivers tighter, more responsive steering with better regrip performance for today's demanding marine applications.

Thank you!

Sender arms were long enough that I could bend arms to match oem.

Great pricing

Just a rating for shopping experience. 4* only because purchase could not be completed w/Apple Pay

I had ordered some CM-19546-A2 (friction-modifier for posi-traction differentials with carbon-fiber clutches) from CJ Pony Parts, and it arrived broken and had all leaked out. I spent $25.42 for nothing, and they still have not responded to my complaint. I bought 2 bottles from THMotorsports in hopes that ONE would arrive undamaged. They arrived in a box, not a bubble mailer like CJ, and both bottles were intact and undamaged. If you're going to buy specialty automotive fluids online, THMotorsports is the better place to do so.
