Important – Electrical Part
Please diagnose the engine fault before purchasing.
Ignition coil faults can have similar symptoms to problems with the CDI/ignition unit, spark plugs, charging system, fuel system or wiring.
Electrical parts that have been fitted or installed cannot be returned unless faulty.
If you are unsure, please send SSI Marine your:
-
Engine HP

Engine serial number

We will be happy to check compatibility before you order.
Buyer Responsibility
It is the buyer's responsibility to confirm compatibility with the engine model and serial number before purchase.
Do not order by horsepower or appearance alone. If the ignition coil looks the same as yours, this does not always mean it is the correct part for your outboard.
