SeaStar BayStar 1.1 Front Mount Hydraulic Helm HH4311-4, Compact Cylinder, 3/4 Inch Tapered Shaft

The SeaStar BayStar HH4311-4 is a front mount hydraulic steering helm built around a balanced, compact-design cylinder that fits most splashwells and delivers full engine movement. It is part of the BayStar 1.1 helm line and is packaged as a complete kit rather than a bare helm, so everything needed for the installation ships together: the helm, the cylinder, fittings, tubing, oil, a fill kit, and detailed instructions.

The helm itself uses a compact body with only a 5 inch footprint and requires just a 3 inch dash hole, whether the boat uses a standard dash or a tilt dash. For boats that want adjustable helm position, an optional five-position tilt helm is available for this system. Steering connects via a standard 3/4 inch tapered steering shaft, and the kit is designed for fast, easy installation without extensive modification to the helm station.

This helm system meets A.B.Y.C. (American Boat and Yacht Council) standards and N.M.M.A. (National Marine Manufacturers Association) certification requirements, so it is suitable for builders and installers who need documented compliance for hydraulic steering systems. Because the cylinder is compact and the helm footprint is small, the HH4311-4 works well on boats with limited splashwell space or tight dash mounting areas where a full-size helm would not fit.
