Important Info

The application chart is just a general guide. Always include your engine model and serial numbers to be sure you receive the correct parts. If possible, also include the part number that's on your old part.

Ignition parts are not returnable. If you have any questions about troubleshooting or ordering the correct part, please contact us before ordering to avoid getting stuck with an incorrect part.


CDI stators and switch boxes for Mercury/Mariner outboards and Sport Jets are covered for two years; triggers, coils, rectifiers, voltage regulators and harnesses are covered for one year.

Part numbers that begin with an R are remanufactured by CDI/Rapair and come with a 90-day warranty. Most "R" part numbers require that you send your old part in to be remanufactured.

Additional Parts Info

174-8778K1 (9 amp) & 174-9710K1 (16 amp) Stators 
These two stators are identical, except for the battery charging output. If you have a voltage regulator with "5279" in the part number, you can use 174-9710K1. If you only have a rectifier, you'll need to use 174-8778K1, unless you upgrade the rectifier to a CDI #194-5279 voltage regulator.

134-6452 and 134-6454 Triggers 
Before ordering, be sure to check your linkage arm to see if it's straight or has a 90 degree hook in it, as shown in the picture. If it's straight, order 134-6452. If it does have a hook in it, order 134-6454. Note that the two parts are not interchangeable.
