SeaStar SSC21906-1 6-Foot JBS Jet Boat Steering Cable
The Dometic SeaStar SSC219061 is the current 6-foot SSC219 / 6400 JBS jet boat steering cable and replaces the previous SSC21906 part number. It is designed for compatible SeaStar jet boat steering helms used with Mercury Sport Jet or OMC Turbo Jet drives that meet ABYC P-23 specifications.
SSC21906-1 is an application-specific steering cable, not a universal mechanical steering cable. Confirm the original cable number, JBS helm and 6-foot length before ordering.
Product Overview
SSC21906-1 is the 6-foot cable in the SSC219 JBS jet boat steering family. It connects a compatible JBS helm to the jet-drive steering nozzle system and is intended for specific Mercury Sport Jet and OMC Turbo Jet applications.
Use this cable when the original cable is marked SSC21906, SSC21906-1 or the older SSC22906 number and the required replacement length is 6 feet. Matching the existing part number is the safest selection method because jet boat steering cables are application-specific.

JBS System Components
The JBS steering system is sold by components. SSC21906-1 is the steering cable only. The helm, bezel and jet-drive connection hardware are selected separately as required by the installation.
How to Confirm the Correct Cable
- Locate the part number stamped or printed on the original steering cable.
- Confirm the original cable belongs to the SSC219 or older SSC229 JBS cable family.
- Verify the cable length is 6 feet. SSC219 cable length is measured from tip to tip.
- Confirm the boat uses a compatible JBS helm and a Mercury Sport Jet or OMC Turbo Jet application.
- Send us clear photos of the cable markings, helm and jet-drive connection if the number cannot be identified.
Use SSC21906-1 When
- The original cable is SSC21906 or SSC21906-1.
- The original cable is legacy SSC22906.
- The required measured length is 6 feet.
- The helm is a compatible SeaStar JBS model.
Do Not Select It By
- Boat make, model or year alone.
- Overall route length without checking the old cable.
- A different rack, rotary or jet boat cable family number.
- Assuming every Mercury or OMC jet application uses SSC219.

- Inspect the helm, bezel, pivots, connection hardware and nozzle linkage when replacing the cable.
- Use genuine replacement hardware designed for the JBS system. Do not substitute unrelated fasteners or steering components.
- Route the cable without sharp bends, crushing, abrasion points or interference with moving components.
- After installation, verify full steering travel and secure operation before launching or operating the boat.
