For high-performance Mercury, Yamaha, and OMC outboard engines, maintaining a strong and reliable ignition system is crucial. When replacing spark plug wires or ignition cables, applying a small amount of Super Lube Dielectric Grease with PTFE to the metal terminals is a simple but essential step.
This grease not only protects against moisture and corrosion but also enhances long-term durability and ease of maintenance—key factors in harsh marine environments.
What Does Dielectric Grease Do for Conductivity?
Dielectric grease is non-conductive, meaning it does not enhance electrical conductivity. However, it improves overall connection reliability by preventing corrosion, oxidation, and water intrusion, which can degrade ignition performance over time. Since marine engines operate in wet, sometimes salty environments, these factors are a major concern.
When applied correctly, dielectric grease does not interfere with the electrical connection because the terminals make direct metal-to-metal contact through pressure. Instead, the grease seals out moisture and contaminants, ensuring a cleaner, stronger connection that prevents misfires and high resistance.
Why Use Dielectric Grease in Marine Applications?
High-performance outboard engines from Mercury, Yamaha, and OMC rely on precise ignition timing and strong spark delivery to maintain peak power. Super Lube Dielectric Grease with PTFE plays a key role in ensuring consistent performance in these demanding conditions.
What is PTFE, and Why is it Important?
PTFE (Polytetrafluoroethylene) is a high-performance synthetic fluoropolymer that enhances the lubrication and protective properties of dielectric grease. PTFE provides additional resistance against moisture, heat, and wear, making it ideal for marine ignition systems.
Key Benefits of PTFE in Dielectric Grease for Outboard Motors:
Enhanced Lubrication: PTFE reduces friction in spark plug boots, making installation and removal easier.
Superior Moisture Resistance: It provides extra protection against water and salt exposure, crucial in marine environments.
Longer-Lasting Protection: PTFE increases the grease’s durability, preventing it from drying out or washing away over time.
Non-Conductive and Chemically Stable: PTFE helps maintain insulation properties while resisting degradation from fuel, oil, and heat.
Should You Use a Lot or a Little?
Only a small amount of dielectric grease is needed. Using too much can cause excess grease to spread, potentially attracting dirt and interfering with the connection. A thin, even layer provides optimal protection without affecting performance.
How to Apply It Properly
Clean the Terminals: Wipe down the metal contacts on the spark plugs and ignition coils with a clean cloth or contact cleaner to remove dirt and oxidation.
Apply a Small Amount: Use a fingertip or cotton swab to apply a thin film of Super Lube Dielectric Grease with PTFE directly onto the metal terminals inside the spark plug boot and coil connections.
Install Spark Plug Wires: Firmly push the boots onto the spark plugs and ignition coils, ensuring a snug and secure fit.
Final Check: Confirm that all boots are fully seated to prevent misfires and water intrusion.
Conclusion
For Mercury, Yamaha, and OMC outboards, proper ignition maintenance is essential for peak performance and reliability in marine environments. Super Lube Dielectric Grease with PTFE is a simple yet powerful tool that protects electrical connections, prevents corrosion, and ensures strong spark delivery—all crucial factors in high-performance marine applications.
By applying a small amount of grease to spark plug and coil terminals, you can extend the life of your ignition system and keep your engine running smoothly on the water.
