SeaStar HK6400-4 Hydraulic Outboard Steering Kit, Single Engine, No Hose

The SeaStar HK6400-4 is a hydraulic steering kit built for single outboard powered boats, sold without hoses so it can be paired with hose lengths and fittings sized to your specific helm layout. It is constructed of metal components designed to deliver the smooth, low-effort steering feel that hydraulic systems are known for, replacing cable steering on runabouts, center console boats, cruisers, and similar single-outboard applications. The kit is intended for boats that are not driven aggressively and do not exceed 75 mph, making it a good fit for typical recreational and light offshore use rather than high-performance racing setups.

Because the HK6400-4 ships without hoses, installers supply hose runs cut to the length needed to reach from the helm pump to the outboard cylinder, along with the fittings required to complete the connection. This lets a single kit serve boats of different lengths without forcing a fixed hose length on the buyer. As a genuine SeaStar part, the HK6400-4 is identified by its own part number so it can be matched precisely against a boat's existing SeaStar hydraulic steering components.
