Description
Dometic SeaStar Outboard Steering Cylinders
SeaStar Outboard Steering Cylinders are engineered for durability, precision, and long-lasting hydraulic performance in demanding marine environments. Designed to resist repeated compression set, these cylinders maintain superior sealing integrity while withstanding heavy steering loads, corrosion, and harsh saltwater conditions.
Ideal for modern outboards that are larger, more powerful, and heavier than ever before, SeaStar cylinders provide smooth, responsive steering with lock-to-lock turns that vary depending on helm selection, allowing you to match steering feel to your boat’s hull design, speed, and intended use.
SeaStar Outboard Hydraulic Steering systems are available in three cylinder models to suit most applications. The most commonly used option is the Front Mount Steering Cylinder (HC5345-3 / HC5347 / HC5348 / HC5358), trusted for its reliability and wide compatibility across single, twin, and triple engine installations.
