OMC 400 Type Cables

What Are OMC 400 Type Cables?

OMC 400 Type cables are specialized throttle and shift control cables designed to work with the original equipment-style control systems found on pre-1979 OMC, Johnson, and Evinrude outboard engines. These cables serve as the mechanical link between the helm's control box and the engine, translating the operator's throttle and gear-shift inputs into precise, reliable engine responses out on the water.

Unlike more universal cable formats, the 400 Type (also referred to as the C4 type) features a specific end fitting configuration engineered to mate with the original OMC control heads used during that era. Whether you're restoring a vintage outboard or simply replacing a worn cable on a classic Johnson or Evinrude rig, using the correct cable type is critical — mismatched fittings can compromise both function and safety.

Why Proper Cable Replacement Matters

Control cables endure constant mechanical stress, saltwater exposure, UV radiation, and temperature cycling. Over time, the cable core can corrode or fray, and the outer conduit can stiffen or crack, leading to sluggish throttle response, missed shifts, or complete loss of engine control. Replacing worn cables promptly with properly rated components keeps your boat safe and your engine performing as intended.

When selecting a replacement OMC 400 Type cable, always measure the existing cable carefully — length matters, as cables are available in a range of sizes from as short as 7 feet to 19 feet or more to accommodate different boat layouts. Also verify your engine's model year and control head style to ensure proper fitment before purchasing.

Uflex brings decades of manufacturing expertise to the OMC 400 Type cable category. Their C4-style replacement cables are designed for pre-1979 Johnson and Evinrude applications and feature an 18-laywire conduit for enhanced efficiency, durability, and reduced bend radius — making them a dependable aftermarket alternative for vintage outboard owners.

Teleflex cables carry the heritage of one of the marine industry's most trusted engineering lineages. Now operating under the SeaStar Solutions umbrella, Teleflex-branded 400 Type cables remain a familiar choice for boaters seeking the original-spec quality that defined decades of Johnson and Evinrude throttle-and-shift systems.

Shopping Tips for OMC 400 Type Cables

• Confirm your engine year: 400 Type cables are specifically designed for pre-1979 OMC/Johnson/Evinrude engines. Post-1979 engines typically require a different cable style (such as the 479 or C14 type).
• Measure carefully: Cable length is measured as the overall cable length; always verify your existing cable length or consult your engine's service manual.
• Check fittings: The 400 Type uses specific end fittings — confirm your control head and engine connection points match before ordering.
• Inspect regularly: Even if a cable appears functional, inspect the conduit and core wire annually for corrosion, kinking, or stiffness, especially in saltwater environments.
