Johnson & Evinrude Outboards Complete Planetary Replacement Mechanical Steering Systems

Planetary mechanical steering systems deliver smooth, precise control by distributing load across multiple gears, making them ideal for higher-horsepower outboards and heavier hulls. Compared to traditional rotary helms, a planetary helm offers reduced wheel effort, improved torque handling, and enhanced durability—especially when paired with no-feedback (NFB) mechanisms that lock out engine torque steer at high speeds. At OBParts.com, you’ll find replacement and upgrade planetary helms from EMP designed to fit replacement familiar brand single- and dual-cable systems. Typical features include compact form factors for tight dashboards, 3–4 turn lock-to-lock ratios for faster wheel response, 3/4" tapered/keyed helm shafts, and compatibility with standard marine steering cables. Many models are drop-in replacements for popular SeaStar/Teleflex, BayStar, and Uflex systems (check each product page for exact cable and bezel requirements).
