DOMETIC SEASTAR 1.7 Cubic Inch Front Mount Hydraulic Steering Helm - HH5271-4

Description

DOMETIC SEASTAR 1.7 Cubic Inch Front Mount Hydraulic Steering Helm – HH5271-4

Dometic SeaStar HH5271-4 is a Gen 4 front-mount hydraulic steering helm with 1.7 cubic inches of displacement per revolution. It is used as the steering pump in SeaStar hydraulic steering systems and is designed for smooth, efficient no-feedback hydraulic steering on many single and multiple outboard applications.

The front-mount design fits common dash layouts and uses ORB-style fittings for modern SeaStar hose systems. Dometic highlights the Gen 4 helm's improved check-valve durability, reduced lock-valve clicking, reduced flow noise coming off hard-over, and tighter steering response compared with older helm designs.

Use this helm only as part of a properly matched SeaStar hydraulic steering system. Cylinder selection, helm displacement, hose routing, engine horsepower, boat speed, and steering wheel diameter all affect final steering feel and system suitability.
