<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>

Great!!

Cannot say enough about how honest these guys are. My order went through without a hitch. Would definitely recommend doing business with them.

Quick shipping, nice easy to use web site, and the lowest price with shipping around.. will use again..

Very quick. Liked that it linked to Amazon. I originally ordered from Amazon who shipped me a front bearing assembly instead of the rear so having to re-order from you. Correct item received this time. Thank you!

I ordered a throttle body spacer from them. They were the cheapest anywhere I've seen. They were very fat at response to my emails. Great place!!

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

Just placed order; seems ok so far
