SeaStar HO5118 Outboard Hydraulic Steering Hose Kit, 18 Feet, Sold in Pairs

The SeaStar HO5118 is a standard-length hydraulic steering hose kit built for outboard steering systems, supplying the hose run between the helm and the outboard steering cylinder. Each hose measures 18 feet and comes with pre-attached fittings on both ends, so there is no separate fitting installation required at hookup. The kit is sold per pair, giving you both the pressure and return hoses needed for a complete single-hose-run connection. Hoses are rated to 1,000 psi, matching the operating pressure of hydraulic outboard steering systems, and are constructed of black synthetic rubber for resistance to marine fuel, oil, and weather exposure.

This hose kit is intended for use with Dometic hydraulic steering systems, with the exception of Dometic PRO, BayStar, Capilano, and 3-line inboard systems, which use different hose or fitting configurations. Because outboard hoses in this series are supplied in fixed standard lengths and cannot be field-cut, the correct part number must be selected for the required run length; the last two digits of the part number indicate the hose length in feet, so HO5118 is the 18-foot version. Installers needing a different length should select the corresponding part in the same series rather than shortening this hose kit.
