<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 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.
