SeaStar HH5272-4 Front Mount 2.4 Hydraulic Steering Helm with ORB Fittings

The SeaStar HH5272-4 is a front-mount 2.4 hydraulic steering helm designed for single-cylinder outboard steering systems. As a 2.4 helm, it is built for applications where faster steering response is wanted compared to a standard 1.7 helm, and it is commonly specified for power-steered setups where quicker response at the wheel matters. The front-of-dash fill design allows for convenient servicing without pulling the helm, and the compact housing needs only a 3 inch dash hole, making it possible to retrofit into an older SeaStar 4.5 inch hole cutout without cutting a new opening in the dash.

Hose connections use positionable stainless steel O-ring boss (ORB) fittings, which let the installer rotate the fitting to the routing angle that works best for the boat's hose runs before final tightening, simplifying installation in tight helm stations. In typical single-cylinder outboard applications, the helm turns 3.5 times lock-to-lock. The compact footprint keeps the helm unobtrusive behind the dash while still housing the full hydraulic pump mechanism needed to drive the steering cylinder.
