SeaStar Helm 1.7 FM ORB Hydraulic Steering Helm, HH5271-4
The SeaStar Helm 1.7 (HH5271-4) is a low friction hydraulic steering helm built for sterndrive boats. It is the standard recommended helm for both non-power and power steered factory stock sterndrive applications, giving boaters a smooth, predictable steering feel at the wheel. The helm uses an FM ORB port fitting and is designed to work with 3/8 inch diameter nylon tubing (Part No. HT5xxx) as part of a complete SeaStar 1.7 hydraulic steering system.
Because it relies on a low friction hydraulic design, the SeaStar Helm 1.7 reduces steering effort compared to mechanical cable systems, while remaining compatible with both non-power assisted and power assisted setups. Boaters running factory stock sterndrive configurations who want faster steering response in a power steered application can instead consider a SeaStar 2.4 helm, but for standard non-power and power steered installations the 1.7 is the baseline recommendation. Note that modified installations may require a higher capacity steering system, so confirm your setup matches factory stock specifications before ordering.
