Product Details

This 6-inch spark plug wire is an aftermarket replacement for the OMC/Johnson/Evinrude spark plug wire reference 582365. It is intended for Johnson/Evinrude outboard applications that use the 6-inch 582365-style wire. Confirm the wire length, terminal configuration, and original part number before ordering.

The wire features an 8 mm silicone jacket, a conductive center core, molded silicone insulation, and corrosion-resistant stainless-steel terminals. Its compact length is suitable for applications where a short individual ignition lead is required.

  • Individual 6-inch replacement spark plug wire.
  • Designed for applications using OMC 582365.
  • 8 mm high-strength silicone jacket for marine service.
  • Stainless-steel terminals help resist corrosion.
  • Aftermarket replacement; not an OMC, Johnson, or Evinrude original-manufacturer component.

Part Number Cross-Reference

The following references are documented for this 6-inch wire. Cross-reference numbers do not replace checking the original wire length and terminal style.

Engine and Application Compatibility

This wire is for Johnson/Evinrude outboard applications using the OMC 582365 specification. Published catalog information identifies 582365 with a 6-inch spark plug wire and lists Sierra 18-8816-1 as a corresponding aftermarket reference.

Because spark plug wire length and terminal configuration can vary between engines, do not rely on horsepower or brand alone. Compare the original wire and verify the exact engine model, year, cylinder location, and ignition-system configuration before installation.

What’s in the Box

  • 1 x 6-inch spark plug wire

Installation Notes

  1. Turn off the engine, allow it to cool completely, and disconnect the battery before servicing the ignition system.
  2. Replace one wire at a time so the cylinder connections are not mixed up.
  3. Twist the boot gently while pulling it from the spark plug. Do not pull on the wire itself.
  4. Disconnect the opposite end from the ignition component and compare the replacement with the original wire before installation.
  5. Verify that the replacement is 6 inches long and that both terminal ends match the original configuration.
  6. Apply a small amount of dielectric grease inside the boot if appropriate for the application. Avoid petroleum-based grease.
  7. Push the replacement boot fully onto the spark plug and connect the other end to the correct ignition terminal.
  8. Route the wire away from hot, sharp, or moving components. Reconnect the battery and check the engine for smooth operation.

Troubleshooting and FAQ

Is this a complete set of spark plug wires?

No. This product is one individual 6-inch spark plug wire. It is not a complete V4 or V6 wire set and does not include multiple wires.

What part does this wire replace?

It is listed as a replacement for OMC part number 582365. Sierra 18-8816-1 is a corresponding aftermarket catalog reference.

Will this fit every Johnson or Evinrude engine?

No. Johnson/Evinrude engines use different wire lengths and terminal configurations. Confirm the original part number, 6-inch length, and terminal style before ordering.

Can I trim the wire if it is too long?

This product is supplied as a 6-inch wire. Do not trim or modify it unless the ignition-system design specifically requires a serviceable cut-to-length lead and you have the correct terminal-installation tools.

What symptoms can indicate a worn spark plug wire?

Possible symptoms include misfires, rough idle, hesitation under load, hard starting, and visible cracking, burning, corrosion, or damage to the wire or boots.

What type of grease should be used on the boots?

Use dielectric grease or silicone tune-up grease sparingly inside the boot to help protect against moisture and ease future removal. Do not use petroleum-based grease.

Is this an OEM part?

No. This is an aftermarket replacement wire. OMC 582365 and Sierra 18-8816-1 are reference numbers used to help identify the application.

Safety and Important Information

  • Verify the original part number, wire length, terminal configuration, and engine application before ordering.
  • This listing is for one individual 6-inch spark plug wire, not a multi-wire set.
  • Disconnect the battery and allow the engine to cool before working on the ignition system.
  • Professional installation is recommended when the correct ignition connections or application cannot be confirmed.
