<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 HH5217-4 is a front-mount, 1.7 cubic inch displacement commercial-grade hydraulic helm pump featuring repositionable stainless steel O-ring (ORB) hose fittings. Widely recognized as the world's most popular hydraulic boat steering helm, it delivers smooth, efficient no-feedback steering for both inboard and outboard marine applications.

Engineered for today's high-performance hulls, this commercial helm supports single or multiple outboard engines up to 700 HP combined and is the OEM choice for center consoles, cruisers, and more. It is suitable for most hydraulic steering applications on inboard, sterndrive, and outboard boats up to 50 feet in length.

Key Features:

  • 1.7 cu. in. displacement front-mount commercial hydraulic helm pump
  • Repositionable stainless steel O-ring (ORB) hose fittings for flexible, leak-resistant hose routing
  • Supports single or twin counter-rotating outboards up to 700 HP combined
  • New valve technology for tighter, quieter, and more responsive steering
  • Greatly reduced chatter noise from overrunning steering loads
  • More durable check valves for improved trailering performance and longer service life
  • Eliminated flow noise when coming off the hard-over position
  • Reduced lock valve spool clicking during steering reversal
  • Revamped aesthetics with new fill port plug design for easier maintenance
  • Fully compatible with existing SeaStar hydraulic steering systems
  • Helm shaft can be mounted horizontally, vertically, or at any angle in between
  • Capable of use in multiple helm station configurations

The HH5217-4 is the current-generation replacement for the HH5217-3 and original HH5217, featuring updated ORB fittings. Use service seal kit HP6037 for helm maintenance. Always use SeaStar Steering Fluid or Mil Spec H5606 fluid — never brake fluid. Do not use Teflon tape or Loctite on fittings, and do not install NPT fittings into the helm pump ports.

Swift with the orders

GREAT TRANSACTION RECEIVED PART IN A VERY TIMELY FASHION

Great price and quick shipping!

I ordered the end links for quite a bit cheaper from THMotorsports that I was able to find them anywhere else including the manufacturer's website, Ebay & Amazon. I expected the shipping to take a week but within two days I was surprised with a package on my doorstep. So early, in fact, that I wondered what the package contained.

Really straight forward

THe site showed that the shocks were backordered for weeks- but THM got my order out in days- very impressive!

Quick online service. Easy website to use.

Seamless as always!

Thank you ...Guys....I REALLY NEED This order for work .... Thank you Sooooooooooo Much...
