<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 DK4220 SmartStick is an advanced non-contact position sensor designed to provide precise steering position feedback for outboard marine applications. This sensor kit mounts directly to SeaStar Solutions front mount steering cylinders (models HC5345 and HC5358), delivering reliable performance without the wear and maintenance issues associated with traditional contact-based sensors.

Key Features:

  • Non-contact sensing technology eliminates moving parts and wear points for long-lasting reliability
  • Fast, convenient installation with no external linkages or complicated mounting hardware required
  • Fully potted electrical components provide superior corrosion resistance in harsh marine environments
  • Integrated electronics within the sensor body simplify cable routing and eliminate the need for external splices
  • Includes 35 feet of marine-grade cable that can be trimmed to any desired length for custom installations
  • Digital electronics provide enhanced immunity to electromagnetic interference (EMI) for consistent, accurate readings

The DK4220 SmartStick kit includes both the sensor and compatible gauge, providing a complete steering position monitoring solution. Ideal for single or twin outboard installations where precise helm angle feedback is critical for autopilot systems, joystick control, or digital steering interfaces.

SmartStick and Gauge Kit

So I left a review already about autoplicity and it was before I even checked when it was going to be delivered. I was happy to see it was already shipped but even more excited and pleased to see that it was only going to take two days to get here! Scheduled for delivery tomorrow! Could not be any happier with this company!

easy to find what you are lokking for and fast shipping.

Great!

Quick and easy. Just hope it fits my car.

We will see when product arrives.

Ordered a Thule ski rack. Best price on the web. Prompt delivery as promised, however, did not get shipping email and tracking no until after delivery was already made. The customer service that I experienced trying to get info on delivery was less than desirable. Four stars o ly.

This is my first time ordering from them, but it certainly will not be my last. They have all the parts I need and the process and ship fast. Great company. And they're prices are awesome.
