Johnson Evinrude OMC Control Cable - 20 ft. | Dometic CCX20520

Dometic CCX20520 | Johnson Evinrude OMC Throttle & Shift Control Cable | 20 ft. | Replaces Seastar CC63620 & Teleflex CCX20520 | MacombMarineParts.com

A worn or stiff throttle and shift control cable makes every docking maneuver harder than it needs to be — and a cable that binds or has excessive lost motion is a safety issue, not just an annoyance. The Dometic CCX20520 is a direct-fit 20 ft. replacement control cable for Johnson, Evinrude, and OMC outboard and turbo jet applications using OMC side mount controls with snap-in OEM-type cable connections. It replaces both the Seastar CC63620 and Teleflex CCX20520, using your existing connection components with no modification required.

Built with a tfXtreme splined coated core element, stainless steel and brass fittings, and a black HDPE outer jacket engineered for UV and chemical resistance.

Additional Information

Why Control Cable Quality Directly Affects Helm Feel and Safety:

Throttle and shift control cables are the mechanical link between your helm controls and your engine — every input you make at the throttle lever travels through the cable before it reaches the engine. A cable with worn core wire, a degraded jacket, or excessive lost motion introduces slop and lag into that connection, which means:

• Imprecise throttle response — you cannot feather the throttle accurately in tight quarters or during docking
• Shift hesitation or hard shifting — worn cables make gear engagement feel notchy or require excessive force
• Safety risk in close-quarters maneuvering — delayed or imprecise control response at low speed is when accidents happen
• Accelerated wear on control heads and engine linkage — a binding cable puts stress on every component it connects to

The Dometic CCX20520 tfXtreme splined core delivers smooth, low-friction operation with minimal lost motion across the full 20 ft. length — so your helm inputs translate directly and predictably to the engine, every time.

Why 20 ft. and How to Choose the Right Length:

Control cable length is determined by the routing path from your helm control head to the engine — not the straight-line distance. A 20 ft. cable is a common fit for center consoles, mid-size runabouts, and larger single-engine layouts where the cable must route through the gunwale, under the deck, and to the engine. When measuring, follow the actual cable path with a tape measure or a length of rope, adding a few inches for connection slack at each end.

Frequently Asked Questions

1. How do I confirm this cable fits my Johnson, Evinrude, or OMC setup?
The CCX20520 is designed for OMC side mount controls that accept OMC snap-in OEM-type cable connections, on Johnson/Evinrude and OMC propulsion systems from 1979 onward. It also directly replaces Seastar CC63620 and Teleflex CCX20520. If you have one of those part numbers on your existing cable, this is the correct replacement. Contact us at MacombMarineParts.com with your engine model, year, and control head model if you need fitment confirmation before ordering.

2. What does drop-in replacement mean for this cable?
Drop-in replacement means the CCX20520 connects to your existing control head and engine linkage using the same connection points as the original cable — no adapters, no modification, no new hardware required. Remove the old cable, route the new one along the same path, and connect at both ends.

3. What is the tfXtreme core and why does it matter?
The tfXtreme splined coated core is Dometic's premium core wire technology — a stainless steel Lubri-Core wire with a splined coating that reduces friction between the core and the cable conduit. The result is smoother throttle and shift feel, less effort at the control head, and reduced lost motion compared to standard uncoated core cables.

4. How do I know when my control cable needs replacing?
Replace your control cable when you notice stiff or jerky throttle movement, excessive play before the engine responds, hard or notchy shifting, visible jacket cracking or fraying, or corrosion at the fittings. Cables in service for more than 5–7 years should be inspected annually even if symptoms are not yet present.

5. Do I need two cables for a single-engine outboard?
Most single-lever control systems use one cable for throttle and one for shift — both the same type and length. If you are replacing both cables (recommended when one shows wear), you will need two CCX20520 cables for a standard single-engine setup.
