Troubleshooting & FAQ
Q: How do I confirm this ignition coil fits my Mercury outboard?
A: Cross-reference your engine's part number with the OEM numbers listed (880615T01 or 339-880615T01). You can also check your engine's HP rating—this coil is designed for Mercury models from 225 HP to 350 HP.
Q: What are the signs that my ignition coil needs replacement?
A: Common symptoms include engine misfires, rough idling, difficulty starting, loss of power, or complete failure to start. If your engine runs inconsistently or fails to ignite, the ignition coil may be faulty.
