Product Details
This 6-inch spark plug wire is an aftermarket replacement lead for selected Johnson/Evinrude outboard ignition systems. It is listed as a 6-inch spark plug wire that replaces OMC part number 582365 and Sierra reference 18-8816-1. Confirm the wire length, terminal style, routing, and part-number match before ordering.
The compact replacement lead is intended for applications that use a separate ignition wire between the ignition coil and spark plug. It is supplied as an individual wire, not as a complete multi-cylinder wire set.
- 6-inch replacement spark plug wire.
- Boot-style ends for the applicable ignition-coil and spark-plug connections.
- Silicone-style insulation is suitable for the heat and moisture commonly encountered in marine engine compartments.
- Sold as one individual spark plug wire.
Part Number Matrix
The references below identify the documented replacement relationship for this 6-inch wire. They should not be used to infer fitment for every Johnson/Evinrude model.
| Brand | Part Number | Reference Type |
|---|---|---|
| OMC / Johnson-Evinrude | 582365 | OEM replacement reference |
| Sierra | 18-8816-1 | Aftermarket interchange reference for a 6-inch spark plug wire |
Engine & Model Compatibility
Fitment depends on the exact engine model, year, ignition configuration, wire routing, and terminal arrangement. The available catalog evidence identifies this wire by its 6-inch length and the OMC 582365 reference, but does not establish a universal 10–235 HP or V4–V6 application range.
Before purchase, compare the original wire with the specifications below and verify that your engine documentation or existing part identifies OMC 582365 or the corresponding 6-inch replacement reference.
| Brand | Application | Length | Stroke | Verified Reference |
|---|---|---|---|---|
| Johnson/Evinrude | Selected applications using OMC 582365; verify exact model and year | 6 inches | Verify for your engine | OMC 582365 |

What’s in the Box
- 1 x 6-inch spark plug wire
This listing is for one individual replacement wire. It does not include a complete V4 or V6 wire set, spark plug, ignition coil, or other ignition components.
Installation Notes
- Turn off the engine, allow it to cool completely, and follow the safety instructions in the engine service manual.
- Identify the wire being replaced and note its routing and connection points before removal.
- Remove the existing wire by gripping the boot rather than pulling on the cable itself. If the boot is stuck, twist it gently to release the seal.
- Compare the replacement wire length, boots, and terminals with the original wire before installation.
- Install the new wire at both connection points, ensuring each boot is fully seated and the conductor is not under tension.
- Route the wire as the original was routed, keeping it away from hot surfaces, moving components, and sharp edges.
- Reconnect the battery if it was disconnected, then inspect the installation before starting the engine.
Troubleshooting & FAQ
How do I know if this wire fits my specific engine?
Confirm that your existing wire is approximately 6 inches long and that your engine documentation or old wire identifies OMC 582365 or the corresponding 6-inch replacement reference. Also compare the boot and terminal arrangement. Model, year, and ignition-system information should be checked before ordering.
Is this a complete set of spark plug wires?
No. This listing is for one individual 6-inch spark plug wire. Engines requiring multiple leads need the appropriate quantity and a separately verified wire set or additional individual wires.
What are the signs of a faulty spark plug wire?
Common symptoms can include misfiring, rough running, difficult starting, reduced performance, or visible cracking, burning, corrosion, or damaged boots. Diagnose the ignition system according to the engine service manual.
How should the wire be maintained?
Inspect the wire and boots periodically for cracking, abrasion, heat damage, moisture intrusion, and loose connections. Keep the wire correctly routed and replace it if the insulation or terminals are damaged.
Is any special tool required for installation?
Routine replacement generally requires no special tool, but a spark plug boot puller may help remove a stubborn old wire without damaging nearby components. Do not pull on the cable itself.
Is this an OEM component?
This is an aftermarket replacement wire, not an OMC, Johnson, or Evinrude branded OEM component. OMC 582365 is provided as the documented replacement reference.
What should I verify before ordering?
Verify the documented replacement number, 6-inch length, boot style, terminal arrangement, wire routing, and the exact engine model and year. A general horsepower range alone is not sufficient to confirm fitment.
Safety & Important Info
- Disconnect power as recommended by the engine service manual and allow the engine to cool before working on the ignition system.
- Verify the original wire length, boots, terminals, routing, and replacement reference before purchase.
- Do not assume that this individual wire fits every Johnson/Evinrude V4 or V6 engine.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended when the correct ignition configuration or fitment cannot be confirmed.
