⚓️💭 Ever heard of indexing your spark plugs? Here’s why Evinrude owners swear by it… Indexing spark plugs might sound technical, but it’s a simple step that makes a big difference to how smoothly your outboard runs. When you “index” a plug, you’re lining up the open end of the electrode so it faces the fuel charge inside the cylinder – giving you cleaner burn, better throttle response, and fewer misfires. 💨🌊 👉🏼 Got questions?
