Troubleshooting & FAQ
How do I confirm fitment?
Compare the engine brand, exact model designation, horsepower, stroke, year, serial range when available, connector arrangement, mounting points, and the part number on your original coil. The tables on this page are application references and should be verified against the engine service information before ordering.
What symptoms can indicate an ignition-coil problem?
Possible symptoms include hard starting, intermittent spark, misfiring, rough running, reduced power, or an engine that will not start. These symptoms can also result from spark plugs, wiring, grounds, switches, or other ignition-system components. Test the complete ignition system before replacing parts.
Is this an OEM Yamaha part?
No. This listing is for an aftermarket replacement ignition coil intended for the applications and replacement references shown above.
Are all listed cross-reference numbers interchangeable?
Cross-reference numbers are provided for identification and application checking. Number appearance alone does not establish interchangeability for every engine. Confirm the exact model and electrical configuration before installation.
Does the package include spark-plug wires or other ignition components?
No. The package contains one ignition coil assembly only unless otherwise stated in the order details. Spark-plug wires, spark plugs, mounting hardware, and other ignition components are not included.
Safety & Important Information
- Disconnect power and follow the engine manufacturer’s safety and service procedures before installation.
- Do not rely on horsepower alone to determine compatibility; model, year, stroke, serial conditions, connectors, and mounting details must also match.
- Compare the replacement with your original component before installation. Do not install it if the terminals, mounting points, or physical configuration differ.
- Professional installation is recommended when testing or servicing marine ignition systems.
