Smooth, precise control starts with dependable boat control cables. These essential components connect your helm to your engine, ensuring responsive throttle, shifting, and steering performance.

Why Replace Your Boat Control Cables?
When throttle or shifting starts to feel stiff, inconsistent, or delayed, it’s time to inspect your control cables. Replacing them ensures:
- Smoother throttle and gear engagement
- Safer, more predictable operation
- Reduced strain on the control head and helm
- Better overall responsiveness on the water
To ensure the perfect replacement, check for your existing cable’s part number or use our A-B-C measurement method to find the correct length. For step-by-step help, see our How to Measure Steering Cables Guide.
Upgrading from Teleflex to SeaStar
Teleflex Marine is now SeaStar Solutions, part of the Dometic Group — continuing the same trusted quality and compatibility. If you’re replacing older Teleflex cables, most new SeaStar models serve as direct replacements, requiring no modification.
