Frequently Asked Questions
What type of engines are these plug wires compatible with?
These Dometic plug wires are designed for gasoline-powered inboard and sterndrive marine engines.
What is the primary benefit of silicone insulation in marine plug wires?
Silicone insulation provides superior resistance to high temperatures, ozone, and moisture, which are common in marine engine compartments, ensuring durability and consistent performance.
How does the stainless steel core contribute to performance?
The stainless steel core offers excellent electrical conductivity for efficient spark delivery and superior resistance to corrosion, a critical factor in the marine environment.
What is RFI and why is suppression important for boaters?
RFI stands for Radio Frequency Interference. Suppressing it is important because it prevents the electrical pulses from the spark plug wires from interfering with navigation and communication electronics like GPS, VHF radios, and fishfinders.
Can I use these plug wires on a diesel engine?
No, these plug wires are specifically designed for gasoline engines and are not compatible with diesel engines.
