OMC 400 Type Cables

What Are OMC 400 Type Cables?

OMC 400 Type cables are a specific pattern of marine throttle and shift control cables designed for pre-1979 OMC, Johnson, and Evinrude outboard engines equipped with BRP/OMC controls. Often referred to as "400 Series" cables, these are the mechanical link that transmits your control lever movements to the engine — enabling precise throttle response and reliable forward/neutral/reverse gear engagement on the water.

While modern boats have largely moved to universal 33C/3300-series cable standards, a significant number of classic Johnson and Evinrude-powered boats still depend on the 400 Type specification. For owners maintaining or restoring these vintage outboards, sourcing the correct replacement cable is critical to safe and predictable boat handling.

Why the Right Cable Matters

Marine control cables endure a punishing environment. As noted by marine rigging experts, these components must withstand constant motion, vibration, salt exposure, and tight routing — all while maintaining smooth, low-friction operation. A worn or corroded cable can cause stiff lever movement, delayed throttle response, or unpredictable shifting, all of which are serious safety concerns underway.

When replacing an OMC 400 Type cable, keep these key considerations in mind:

• Correct cable type: Confirm your engine and control box require the 400 Type specification, not the universal 33C pattern.
• Accurate length measurement: These cables are available in a wide range of lengths (typically 7 ft to 24 ft). Measure your routing carefully, following manufacturer guidelines for bend radius.
• End fittings: Some 400 Type cables use bare wire ends and require reuse of the original removable end fittings and set screws from your old cable.
• Material construction: Look for stainless steel core wires and brass or stainless fittings with moisture-protective seals for maximum corrosion resistance in the marine environment.

Top Brands for OMC 400 Type Cables

SeaStar Solutions is the most recognized name in this category. Their CC170 series cables are direct-replacement shift and throttle cables engineered specifically for pre-1979 OMC, Johnson, and Evinrude applications. SeaStar's 400 Series cables feature stainless steel and brass fittings with a stainless steel Lubri-Core wire for smooth, consistent operation across a full range of lengths.

Uflex is a well-regarded marine controls manufacturer offering a broad selection of 400 Type compatible cables. Uflex products are known for their 18-laywire conduit construction, which is designed to enhance efficiency, durability, and longevity — an important trait for cables that see frequent use through a full boating season.

Teleflex has a long legacy in marine steering and control systems and produces connection kits and cables compatible with the 400 Type standard, including engine-specific adapter kits for 1973–1978 OMC applications. Teleflex products are known among marine mechanics for their precise fitment and reliable performance.

Finding the Right OMC 400 Type Cable

To find the correct cable for your application, start by confirming your engine year and model (400 Type cables serve pre-1979 OMC, Johnson, and Evinrude outboards), then measure your cable run from the control box to the engine. Always cross-reference the OEM part number when possible, and consider marine-grade stainless and corrosion-protected options for the longest service life. With the right cable in hand, restoring crisp, responsive control to a classic outboard is a straightforward job.
