Installation Guide

  1. Ensure the engine is off and completely cool. Disconnect the negative battery terminal for safety.
  2. Identify the spark plug wire to be replaced. Note its routing from the distributor/coil to the spark plug.
  3. Gently twist the boot and pull it straight off the spark plug. Do not pull on the wire itself, as this can damage the terminal.
  4. Disconnect the other end of the wire from the distributor cap or ignition coil.
  5. Compare the new wire with the old one to ensure they are the same length and have the same style of boots.
  6. Apply a small amount of dielectric grease to the inside of the new boots to prevent corrosion and ensure a tight seal.
  7. Firmly press the spark plug boot onto the spark plug until you feel it click into place.
  8. Connect the other end to the corresponding terminal on the distributor cap or coil, ensuring it is secure.
  9. Reconnect the negative battery terminal.
  10. Start the engine to verify proper operation and check for any rough idling or misfires.

Troubleshooting & FAQ

Q: How do I confirm this wire fits my Johnson/Evinrude engine?

A: This wire fits most V4-V6 CROSSFLOW engines from the 1980s-1990s, covering a wide range from 10-235 HP. The best way to confirm fitment is to match your existing part number to one listed in our cross-reference table, such as 582365 or Sierra 18-5231-1. You can also verify your engine model against the compatible models list on this page.

Q: What are the signs that a spark plug wire needs to be replaced?

A: Common signs of a failing spark plug wire include engine misfires, rough idling, difficulty starting, reduced acceleration, and poor fuel economy. You should also replace wires if you see any visible damage, such as cracks in the silicone jacketing, burn marks, or corrosion on the metal terminals.

Q: Is there a performance difference between this and the original OEM wire?

A: This is an aftermarket part built to meet or exceed OEM specifications. It features a durable stainless steel wound conductor, premium silicone jacketing, and excellent RFI suppression to deliver performance and longevity comparable to the original factory part.

Q: How often should I replace my outboard's spark plug wires?

A: There is no universal replacement interval, but it is good practice to inspect them annually for wear or damage. We recommend replacing them every few years as part of your regular engine maintenance schedule to ensure peak ignition performance and reliability.

A sock with real support and thickness!
Size: Large, Color: (001) Black / Black / Pitch Gray
I’m pretty happy with these. It seems like sock manufacturing changed 10-15 years ago, and it’s become hard to find pairs that are actually thick and durable. I bought these for an event where I knew I’d be on my feet all day, and they did not disappoint. They provided excellent support throughout the day, even while wearing shoes that typically make my feet ache after just a couple of hours. Glad to finally find a pair that feels well-made.
