SeaStar HH6543-4 Helm 2.0 Classic Tilt Hydraulic Steering Helm, ORB Ports, All-Metal Construction

The SeaStar HH6543-4 Helm 2.0 Classic Tilt is a hydraulic steering helm built for smooth, super-efficient control at the wheel. It is constructed of 100% metal for durable, long-term performance on the water, and its Classic Tilt design fits standard tilt steering columns for a comfortable, adjustable helm position. The helm uses ORB (O-ring boss) porting for the hydraulic hose connections, providing a secure, leak-resistant seal at the fitting points.

As the core control unit of a hydraulic steering system, the Helm 2.0 Classic Tilt translates wheel input into steering ram movement, giving the operator direct, responsive command of the vessel. It is designed as a standalone helm unit within a broader hydraulic steering setup rather than a full kit, so it is intended to be installed alongside compatible SeaStar hydraulic steering components.
