Product Details
This 6 in. marine spark plug wire lead set includes four replacement leads for selected Johnson, Evinrude, and OMC outboard applications. The leads are intended for coil-to-spark-plug service where the existing wire length, terminal style, boot configuration, and reference number match the replacement set.
The listed cross-references include Johnson/Evinrude numbers 582134, 582135, 582365, 777703, 802466, and 802505; Sierra 18-8816-1; CDI 931-2365; and Mallory 9-28005 and 9-28006. Cross-reference listings are provided for identification only. Confirm the complete engine model, year, serial-number range, terminal and boot configuration, and original part number before ordering.
- Four 6 in. spark plug wire leads for a complete wire replacement service.
- Designed for coil-to-spark-plug applications on compatible outboard engines.
- Aftermarket replacement component; not an OEM-manufactured part.
- Verify physical dimensions and connector/boot configuration before installation.

Installation Notes
- Turn the engine off and allow it to cool completely before beginning work.
- Disconnect the battery according to the engine manufacturer’s service procedure.
- Label the existing wires and replace one wire at a time to preserve the correct firing order.
- Remove each old lead by gripping and twisting the boot rather than pulling on the wire itself.
- Compare the replacement lead with the original for length, terminal style, and boot position before fitting it.
- Push the replacement boot firmly onto the spark plug and coil connection. Do not cut or modify the wire unless the applicable service instructions specifically require it.
- Reconnect the battery, start the engine, and check for stable operation after all connections have been inspected.
Troubleshooting & FAQ
How can I confirm these wires fit my specific engine?
Match the original wire length, boot and terminal configuration, engine model, year, serial range, and reference number against the information above. Because the listed application range covers multiple outboard configurations, do not rely on horsepower or the V4/V6 designation alone.
Do I need to cut or modify the wires?
The wires should not be cut as part of normal installation. If the boot or terminal does not match the original component, stop installation and verify the part number and application rather than forcing or altering the lead.
What are common signs of a failing spark plug wire?
Possible symptoms include misfiring, rough idle, hesitation under load, poor acceleration, or reduced engine performance. Inspect the wire insulation, boots, and terminals for cracking, burning, looseness, moisture intrusion, or corrosion before replacement.
Is this an OEM part?
No. This listing is for an aftermarket replacement lead set. The reference numbers identify potential cross-reference applications and do not indicate that the product was manufactured by the original equipment brand.
What should I do if the physical parts do not match?
Do not install a lead with a different length, boot, or terminal configuration. Compare the part with the original component and confirm the engine model, year, serial range, and reference number before contacting the seller for assistance.
Safety & Important Information
- Always verify the complete engine model, year, serial range, and original wire configuration before ordering.
- Do not rely on a broad horsepower range or engine family designation as the sole fitment check.
- Disconnect the battery and follow the engine manufacturer’s service and safety procedures during installation.
- This is an aftermarket replacement and is not an OEM component.
- Professional installation is recommended when the correct firing order, terminal configuration, or ignition-system procedure is uncertain.
