PartsDuck just added one of the biggest names in marine steering, controls, and onboard equipment.
Dometic marine products are now live at PartsDuck — including a huge selection of SeaStar and BayStar steering and control products.
Our new Dometic catalog currently includes more than 760 products, covering everything from hydraulic steering cylinders and helms to mechanical steering cables, shift and throttle controls, jack plates, trim tabs, refrigeration, sanitation, climate-control parts, and more.
And if you know Dometic mainly because of SeaStar, you’re not alone.
SeaStar is the centerpiece of this launch.
PartsDuck now carries more than 680 SeaStar and BayStar steering and control products, making this one of the largest new product-family additions we’ve made.

What Is SeaStar?
SeaStar is Dometic’s marine steering and controls line, covering hydraulic steering, mechanical steering, helms, cylinders, hoses, shift and throttle cables, power-assist systems, jack plates, and related marine control hardware.
For many boat owners and technicians, the SeaStar name is already closely associated with marine steering.
That’s why this launch is such a big addition for PartsDuck.
Is SeaStar Made by Dometic?
Yes.
SeaStar products are now sold as part of Dometic’s marine steering and control portfolio.
Dometic’s current steering lineup includes familiar names such as SeaStar, BayStar, Xtreme, and Optimus.
That means when you shop SeaStar products on PartsDuck, you’ll often see them listed under the Dometic brand while still carrying the SeaStar product-family name you already recognize.
Dometic Marine: A Lot More Than Refrigerators
Dometic is a major name in mobile living, but the company’s marine business reaches far beyond refrigeration.
Its marine product range includes marine steering, shift and throttle controls, hydraulic systems, mechanical steering, jack plates, trim systems, refrigeration, climate-control equipment, sanitation, and marine accessories and service parts.
That makes Dometic unusual because one manufacturer can touch the helm, engine controls, refrigeration, sanitation, trim, and comfort systems on the same boat.

SeaStar Steering Is Now at PartsDuck
For a lot of boat owners and marine technicians, the name SeaStar is practically synonymous with marine steering.
SeaStar steering systems are found across a huge range of boats, including center consoles, bass boats, bay boats, pontoons, offshore boats, runabouts, sterndrives, inboards, and multi-engine boats.
PartsDuck now carries a deep SeaStar and BayStar catalog covering complete systems and individual service components.

SeaStar Hydraulic Steering
Hydraulic steering is where SeaStar is especially well known.
PartsDuck currently carries more than 230 Dometic hydraulic steering products, including complete steering kits, hydraulic helms, outboard steering cylinders, inboard cylinders, steering hoses and tubing, hydraulic fittings, steering service parts, power-assist components, and related mounting hardware.
Shop Dometic Hydraulic Steering →
SeaStar HK6400-4 Hydraulic Steering Kit
One of the most recognizable SeaStar steering packages is the Dometic SeaStar HK6400-4 Hydraulic Steering Kit.
The current PartsDuck listing includes a SeaStar hydraulic helm, front-mount outboard steering cylinder, and steering fluid. Hoses are sold separately so the correct type and length can be selected for the specific boat.
SeaStar PRO Hydraulic Steering
Higher-performance applications may call for SeaStar PRO.
PartsDuck carries the Dometic SeaStar PRO HK7500-4 Hydraulic Steering Kit.
Dometic positions SeaStar PRO for specific high-performance single-outboard applications rather than as a universal upgrade for every boat.
The correct steering system should always be matched to the engine, hull, speed, steering load, and current Dometic application guidance.
SeaStar Hydraulic Steering Cylinders
The cylinder is where hydraulic pressure becomes actual engine movement.
Shop Dometic Hydraulic Steering Cylinders →
One of the best-known products in the SeaStar lineup is the Dometic SeaStar HC5345-3 Front-Mount Outboard Steering Cylinder.
The current PartsDuck listing identifies the HC5345-3 as a standard front-mount SeaStar cylinder with an 8-inch stroke, 8.34 cu. in. displacement, and adjustable ORB fittings.
As with any steering component, fitment should be verified against the exact engine and Dometic application information before ordering.
SeaStar Steering Helms
At the other end of the hydraulic system is the helm.
The helm pump converts steering-wheel movement into hydraulic pressure that moves the steering cylinder.
PartsDuck currently carries more than 40 Dometic steering helms.
One example is the Dometic SeaStar HH5271-4 1.7 Front-Mount Hydraulic Helm.
SeaStar Hoses, Tubing & Service Parts
A hydraulic steering system is only as good as the components connecting it.
Dometic Steering Hoses & Tubing →
Dometic Steering Service Parts →
That includes hoses, fittings, adapters, seal-related parts, hardware, and other service components.
For example: Dometic SeaStar HF5528 Straight Steering Fitting Kit →
BayStar Hydraulic Steering
SeaStar isn’t the only hydraulic steering system in the Dometic family.
BayStar is another familiar name, especially for many lower-horsepower single-outboard applications.
PartsDuck carries the Dometic BayStar HK4300-4 Hydraulic Steering Kit.
Dometic currently rates BayStar for many single-outboard applications up to 150 HP, but it is not intended for every boat within that horsepower range.
High-performance, high-steering-load, pontoon, or other specialized applications may require SeaStar instead.
That’s why we’re building a separate guide: SeaStar vs. BayStar: Which Hydraulic Steering System Do You Need?
Mechanical Steering Is Still a Big Part of the Line
Not every boat needs hydraulic steering.
Mechanical steering is still used on thousands of smaller boats, older boats, pontoons, and lower-load applications.
PartsDuck currently carries more than 180 Dometic mechanical steering products.
Shop Dometic Mechanical Steering →
The lineup includes rotary steering systems, rack-and-pinion systems, mechanical helms, steering cables, Xtreme steering products, and replacement hardware.
SeaStar Xtreme Shift & Throttle Cables
The SeaStar name also goes beyond steering.
PartsDuck carries approximately 170 Dometic shift, throttle, and utility cables.
Shop Dometic Shift, Throttle & Utility Cables →
The lineup includes SeaStar Xtreme cable families for Mercury Gen I / 600A applications, Johnson/Evinrude / OMC applications, 33C-style controls, and heavy-duty 4300 / 43-series systems.
Dometic Marine Engine Controls
Cables are only part of the control system.

SeaStar Power Assist
Larger engines and higher steering loads can make even a hydraulic steering system feel heavy.
SeaStar Power Assist adds powered hydraulic assistance to compatible SeaStar steering systems.
PartsDuck carries products including the Dometic SeaStar PA1200-3 Power Assist and Dometic SeaStar PA1200-3HP High-Pressure Power Assist.
Power Assist is application-specific. One important manufacturer warning: SeaStar Power Assist should not be used with BayStar steering cylinders.
SeaStar Jack Plates
Steering isn’t the only performance-related hardware in the SeaStar lineup.
Dometic SeaStar Jack Plates & Accessories →
Jack plates allow an outboard engine’s vertical position to be adjusted relative to the transom and can help with engine-height tuning, shallow-water operation, hole shot, propeller bite, water pressure, and performance setup when properly configured.
Dometic Trim Tabs
Dometic’s marine control catalog also extends into ride and trim control.

Dometic Refrigeration
Dometic is also one of the best-known names in onboard refrigeration.

Dometic NRX Compressor Refrigerators →
One example is the Dometic NRX 50S Stainless Steel Compressor Refrigerator.
Dometic Sanitation Products
Dometic has been a major name in marine sanitation for years.

Why SeaStar Matters to PartsDuck
There are brands in the marine industry that become so established that boaters stop thinking of the category separately from the brand.
SeaStar is one of them.
If someone says, “I need a SeaStar cylinder,” a marine technician generally knows exactly what kind of system they’re talking about.
For PartsDuck, adding Dometic isn’t just adding another brand.
It fills in one of the biggest missing pieces in our catalog.
We already carry the parts that make the engine run.
Now we’re substantially expanding what happens between the steering wheel and the engine.
