New Mercury & Mariner Outboard Planetary Mechanical Steering Helms

Enhance marine steering performance with OBParts' Plantery Mechanical Steering Helms—innovative, high-quality steering solutions designed for reliability and precision. Built around a planetary gear system, these helms offer three internal gears that distribute torque efficiently across multiple load points. That results in smoother operation, longer system life, and reduced helm feedback. Crafted for marine environments, the helms use corrosion-resistant materials (like stainless steel outputs) and a compact form factor for seamless dash integration. Their fast-connect, easy-install design ensures straightforward setup—whether replacing older systems or upgrading to efficiency-focused steering.
