This three-piece ignition cable set is designed to fit Mercury 65–90HP 3-cylinder engines, offering a precise length and heavy-duty core that maintain consistent spark delivery. Each wire is 9 inches long with an 8 mm diameter copper core, assembled and tested new before shipment to ensure dependable performance on the water.

How does this wire set fit my Mercury 65–90HP 3-cylinder engine?

The LIZAPUS set is tailored to the physical and electrical requirements of Mercury 65–90HP 3-cylinder outboards. With factory-matching length and high-tension specification, installation is straightforward and restores correct spark gap timing when replacing worn or damaged wires.

• Direct compatibility for Mercury 65–90HP 3-cylinder models
• Three wires supplied to replace the full cylinder bank
• 9-inch length matches OEM routing and boot positions
• Pre-tested units reduce guesswork during installation

What materials and construction improve performance?

Each ignition wire uses a copper-based core engineered for low electrical resistance and efficient energy transfer to the spark plug. Robust insulation and properly fitted terminals protect against moisture, arcing, and heat—helping maintain consistent combustion under marine conditions.

• 8 mm copper core for effective spark conduction
• Durable outer insulation to resist saltwater and heat exposure
• Securely fitted ends to minimize misfires and arcing
• Factory testing confirms continuity and build quality

How simple is installation and what’s included?

Installation is designed to be quick and intuitive for anyone replacing a full set of plug wires. The package contains all three wires necessary for a complete cylinder replacement, sized to match original routing so you can reconnect without trimming or splicing.

• Package includes 3 ignition spark plug wires
• No modification typically required for standard Mercury 65–90HP setups
• Replace all cylinder leads at once to ensure balanced ignition
• Ships new and tested to reduce installation troubleshooting

Will these wires withstand marine conditions?

The set is built with materials chosen for corrosion resistance and thermal endurance common in marine environments. Properly sealed boots and quality conductors help prevent performance loss from exposure to moisture, salt spray, and engine heat.

• Corrosion-resistant terminals and insulation materials
• Heat-tolerant construction for engine bay placement
• Designed to reduce moisture-related arcing and misfires
• Tested units shipped new to ensure out-of-the-box reliability

Who is this for: Boat owners, marine technicians, and DIYers who need a reliable, OEM-length replacement ignition wire set for Mercury 65–90HP 3-cylinder outboards. If your engine shows signs of ignition wear, rough idle, or you’re performing preventative maintenance, this LIZAPUS 3-piece kit provides a direct-fit, tested solution to restore dependable spark delivery.
