Engineering Heritage That Sets the Standard

For almost six decades, SeaStar has been providing innovative boating solutions. The company first brought radical changes to small boat steering in 1962 with the Big-T cable steering system, and during the following decades introduced many firsts — including the first tilt steering for recreational boats, CANBUS technology for steer-by-wire control, and push/pull control cables that ensured superior reliability.

From throttle and shift control cables to instrumentation and repair parts, SeaStar Solutions has continually led the recreational marine industry with innovation, quality, and a commitment to supplying boat builders, dealers, and boaters with the parts they need. Critically, each system is designed for easy installation, durable operation, and compatibility with SeaStar Solutions (Teleflex) steering cables — so whether you're replacing a worn unit or upgrading to a newer series, cross-system compatibility is built in.

Broad Engine Compatibility

When properly installed, SeaStar engine controls connect to outboard, stern drive, and inboard engines, utilizing Mercury/Mariner and OMC OEM type control cables as well as universal 3300/33C type cables and engine connection kits. This broad compatibility makes SeaStar controls a practical choice for mixed fleets and legacy systems alike.

Whether you need a complete replacement control box or just a neutral safety switch, cable hardware kit, or a control fluid top-up, SeaStar Solutions has the part. Browse the full Control Boxes & Parts category or explore everything SeaStar Solutions offers across their complete marine lineup.
