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>

The Seastar Solutions HC53703 is a side-mount outboard steering cylinder designed for reliable marine steering performance. This cylinder is part of Seastar's comprehensive line of hydraulic steering components, engineered to deliver precise boat control and long-lasting durability in harsh marine environments.

Key Features:

  • Side-mount configuration for flexible installation options on various hull designs
  • Hydraulic cylinder construction with corrosion-resistant materials for marine use
  • Compatible with Seastar hydraulic steering systems for single outboard engines
  • Precision machined components ensure smooth, responsive steering feedback
  • Sealed design protects internal components from water and contaminants
  • Direct replacement for existing Seastar side-mount cylinders

This side-mount cylinder is ideal for installations where space constraints or transom design make front-mount or splashwell-mount cylinders impractical. The HC53703 provides the same reliable hydraulic steering performance Seastar is known for, with mounting flexibility for custom or tight-space applications.

All good so far. Could be a little clearer about if the order will include needed any additionally needed hardware for install.

This was my first order but will definitely use them again. Best price and quick shipment.
