Seastar Solutions HH4315-4 BayStar Sport Tilt Hydraulic Helm 1.4 Cu. In. ORB

The Seastar Solutions BayStar HH4315-4 is a 1.4 cubic inch hydraulic sport tilt helm pump designed for outboard-powered boats rated up to a maximum of 150 horsepower. Part of the trusted BayStar hydraulic steering lineup — manufactured by the makers of SeaStar, the most recognized name in marine steering — this helm delivers smooth, reliable hydraulic steering performance with an updated fourth-generation design.

The HH4315-4 features an updated valve system engineered to provide tighter, quieter, and more responsive steering while reducing chatter caused by overrunning steering loads. More durable check valves improve overall system resilience, including better trailering performance and extended service life. The revamped exterior design enhances aesthetics and introduces a new fill port plug for easier maintenance.
