The ignition coil is a critical component of the outboard’s ignition system — it transforms battery voltage into the high-voltage spark required to fire the spark plugs at precisely the right moment. A failing coil causes misfires, hard starting, rough running, and power loss under load.\u003c\/p\u003e\u003cp\u003ePart number 806673T1 is a genuine Mercury OEM replacement coil, ensuring correct output voltage, timing compatibility, and service life for compatible Mercury outboard engines. Using an OEM coil eliminates the fitment and performance uncertainty that can come with aftermarket substitutes on high-performance marine ignition systems.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 806673T1\u003c\/li\u003e\n\u003cli\u003eGenuine Mercury OEM ignition coil\u003c\/li\u003e\n\u003cli\u003eDelivers correct high-voltage output for reliable spark at all RPM ranges\u003c\/li\u003e\n\u003cli\u003eDirect OEM fit — no modification required\u003c\/li\u003e\n\u003cli\u003eRestores ignition performance on engines with misfires, hard starting, or rough running\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eBest suited for replacing a failed or degraded ignition coil on compatible Mercury outboard engines. Symptoms of a failing coil include intermittent misfires, hard starting (especially when warm), rough idle, hesitation under acceleration, and cylinder-specific power loss. Always diagnose which coil is failing before ordering — on multi-coil engines, test each coil individually. Confirm engine model, year, and serial number against the Mercury parts catalog before ordering to ensure 806673T1 is the correct coil for your application.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eIgnition coils are a high-value diagnostic part — customers replacing one are often doing so after a misfire diagnosis, which means they may also need spark plugs and a full ignition service. Always ask whether they’ve checked the spark plugs and plug wires at the same time.
