⚠️ Important – Check Compatibility
Please check your engine serial number and original ignition coil part number before ordering.
Mercury used different ignition coils across similar horsepower engines.
Appearance alone does not confirm compatibility.
If unsure, send SSI Marine your engine horsepower + complete serial number and we will help check compatibility.
What's Included
1 × Ignition Coil
Please note: 3-cylinder engines use three ignition coils. This listing is for ONE coil unless otherwise stated.
Buyer Responsibility
It is the buyer's responsibility to confirm compatibility before purchasing.
Ignition faults should be correctly diagnosed before replacing the coil, as spark plugs, wiring, ECU/CDI or other ignition components can produce similar symptoms.
