STEERING HYDRAULIC STEERING / STEERING KITS / INBOARD & STERNDRIVE
SEASTAR 2-LINE INBOARD STEERING
System Overview: The most popular inboard hydraulic steering system offers unmatched comfort and control for today’s inboards up to 50 feet. A wide range of helm and cylinder displacements covers most applications. Applications: Most inboard powered boats with single or dual engines: single engine planing/displacement hull craft from 26-44 feet; dual engine planing hull craft from 26-50 feet; dual engine displacement hull & sail craft from 26-44 feet. Suitable for dual station use with purchase of extra hardware. Features: • Low friction hydraulic steering system. • Configurations for most inboards. • Compact helm has only a 4-7/16” foot print — needs only 3” dash hole (Tilt requires larger hole). • Standard 3/4” tapered steering shaft. • Easy installation on single or dual rudders. • Cylinders supplied with bleeder fittings. • Regular duty aluminum or heavy duty brass cylinders. Two-axis articulation. • Meets A.B.Y.C. standards.
